ABSTRACT.
One of the main objectives of sugarcane plantations is to increase their longevity without decreasing agricultural productivity. In the present study, we analyzed the proteome of the axillary buds of ‘RB966928’ to investigate possible changes in the number of proteins at different cutting stages. Using tryptic digestion followed by ultra-performance liquid chromatography coupled with high-resolution time-of-flight mass spectrometry, 122 proteins were identified from the proteome of the axillary buds of ‘RB966928’. Of the 122, respectively 97 and 95 proteins were detected at the first and fifth cutting stages, of which 27 and 25 proteins were unique to the respective stage. Proteins that prevent the misfolding of polypeptides generated under stress were exclusively detected at the first cutting stage. Meanwhile, proteins associated with stress responses and disease resistance were exclusively detected at the fifth cutting stage. The present proteomic analysis in the regrowth cycles and axillary bud development of ‘RB966928’ significantly advanced our understanding of the biological processes linked to the reduction of agricultural productivity of sugarcane with the advancement of cutting age. Absence of proteins to tolerate adverse growth conditions at the fifth cutting stage may be related to reduced agricultural productivity, in addition to environmental stress, soil compaction, nutrient availability, cultural practices, and pests or pathogen attacks at different phenological stages of crops.

Introduction
Increasing the longevity of sugarcane (Saccharum spp.) plantations without decreasing agricultural productivity is one of the main objectives of sugarcane cultivation. The productive cycle (longevity) of most sugarcane varieties in Brazil averages six years, with five cutting stages (Salomé, Sakai, & Ambrosano, 2007Salomé, J. L., Sakai, R. H., & Ambrosano, E. (2007). Viabilidade econômica da rotação de adubos verdes com cana-de-açúcar. Revista Brasileira de Agroecologia, 2(2), 116-119.; Santos & Borém, 2013Santos, F., & Borém, A. (2013). Cana-de-açúcar - do plantio à colheita. Viçosa, MG: UFV. ). Although it is common to find sugarcane at the fifth cutting stage, decrease in agricultural productivity is evident and intrinsic in each cultivar due to advanced cutting age (Dias, 2011Dias, L. A. S. (2011). Biofuel plant species and the contribution of genetic improvement. Crop Breeding and Applied Biotechnology, 11(spe), 16-26. DOI: https://doi.org/10.1590/S1984-70332011000500004

Genetic improvement of sugar cane for bioenergy: the Brazilian experience in network research with RIDESA. Crop Breeding and Applied Biotechnology, 12(suppl.), 87-98. DOI: https://doi.org/10.1590/S1984-70332012000500010
https://doi.org/https://doi.org/10.1590/...
). Moreover, this reduction in agricultural productivity may be related to environmental stresses, soil compaction, nutrient availability, cultural practices, and pest or pathogen attacks at different phenological stages of crops (Manhães, Garcia, Francelino, Francelino, & Coelho, 2015Manhães, C. M. C., Garcia, R. F., Francelino, F. M. A., Francelino, H. O., & Coelho, F. C. (2015). Factors that affect sprouting and tillering of sugar cane. Revista Vértices, 17(1), 163-191. DOI: https://doi.org/10.5935/1809-2667.20150011
https://doi.org/https://doi.org/10.5935/...
).
Changes in allele number and mean observed heterozygosity of the expressed sequence tag-simple sequence repeat (EST-SSR) loci at different (second, fourth and sixth) cutting stages have been detected in sugarcane cultivars ‘RB72474’ and ‘RB867515’ (Augusto, Maranho, Mangolin, Bespalhok Filho, and Machado, 2017Augusto, R., Maranho, R. C., Mangolin, C. A., Bespalhok Filho, J. C., & Machado, M. F. P. S. (2017). Changes on microsatellites of expressed sequence tag of sugarcane (Saccharum spp.) during vegetative propagation. Genetics and Molecular Research, 16(1), 1-11. DOI: https://doi.org/10.4238/gmr16019519
https://doi.org/https://doi.org/10.4238/...
). However, similarities and differences in 10 Est-SSR loci at the molecular level between ‘RB72454’ and ‘RB867515’ during subsequent cutting stages could not explain the frequently observed reduced productivity, but the differences reveal that phenotypic and physiological changes following each cutting stage were accompanied by changes at the genomic level. Biotic and abiotic factors may induce changes in gene expression, further decreasing the agricultural productivity of cultivars with high yield and wide adaptability (‘RB72454’) or high yield and sucrose content (‘RB867515’), which are particularly important for ethanol and sugar production. Proteins and a set of proteins and polypeptides acting in response to different biotic and abiotic factors may be found in the proteome of axillary buds of sugarcane. Sprouting of axillary buds is important to generate vigorous plants for the cultivated area and the interaction between genotype and environment should produce a proteome that allows the survival and continuity of production.
Proteomic analysis in sugarcane has been an useful tool for identification of proteins that responded to drought stress (Khueychai et al., 2015Khueychai, S., Jangpromma, N., Daduang, S., Jaisil, P., Lomthaisong, K., Dhiravisit, A., Klaynongsruang, S.

https://doi.org/https://doi.org/10.1007/...
). A reduction in the number of proteins in the axillary buds of ‘RB867515’ at the fifth cutting stage has been also demonstrated by Maranho et al. (2019Maranho, R. C., Benez, M. M., Maranho, G. B., Neiverth, A., Santos, M. F., Carvalho, A. L. O., ... Machado, M. F. P. S. (2019). Proteomic analysis of axillary buds of sugarcane at different cutting stages: evidence for alterations in axillary bud gene expression. Crop & Pasture Science, 70(7), 622-633. DOI: https://doi.org/10.1071/CP19115
https://doi.org/https://doi.org/10.1071/...
). The above indicates reduction in the expression of genes that may be essential for the stability of the culture development.
Changes in gene expression of the axillary buds at the fifth cutting were detected in ‘RB867515’, and such changes may or not may be observed in other sugarcane cultivars. Since the establishment, maintenance, and expansion of a sugarcane farm depend on the budding potential of the axillary buds, the present study investigated whether reduction in the number of proteins from the first (plant cane) to the fifth (forth ratoon) cutting stage is an evidence that may be extended to other sugarcane cultivars important to the sugar and alcohol industries, such as ‘RB966928’. ‘RB966928’ was developed through a cross between ‘RB855156’ and ‘RB815690’ and was released by the Federal University of Paraná in 2010. ‘RB966928’ is preferred by producers due to its qualities, such as high sucrose content at the beginning of the harvest; tall size; high tillering; eventual overturning; early maturation; high growth rate; indication for cultivation in a medium or under high-potential environments; and resistance to sugarcane smut (Sporisorium scitamineum), brown rust (Puccinia melanocephala), scald (Xanthomonas albilineans), and sugarcane mosaic virus (Potyvirus sp.). In addition, RB966928 stands out for its performance in both mechanized planting and harvesting (RIDESA, 2010RIDESA. (2010). Catálogo Nacional de variedades “RB” de cana-de-açúcar. Curitiba, PR: RIDESA. ; Daros, Oliveira, & Barbosa, 2015Daros, E., Oliveira, R. A., & Barbosa, G. V. (2015). 45 anos de variedades RB de cana-de-açúcar: 25 anos de RIDESA. Curitiba: PR, Graciosa.). In the 2017-2018 varietal census of the Instituto Agronômico de Campinas, ‘RB966928’ was the second most planted cultivar in the southern and central regions of Brazil (12.5% of total area) and the most planted cultivar for the renewal of sugarcane fields in the state of São Paulo, Brazil (Braga Junior et al., 2019Braga Junior, R. L. C., Landell, M. G. A., Silva, D. N., Bidóia, M. A. P., Silva, T. N., Thomazinho Junior, J. R., Anjos, I. A. (2019). Censo varietal IAC de cana-de-açúcar no Brasil - Safra 2017/2018 e na região centro-sul - Safra 2018/19. Campinas, SP: Instituto Agronômico. (Boletim Técnico, IAC 225).).
To this end, we analyzed the proteome of the axillary buds of ‘RB966928’ to investigate the possible changes in the number of proteins at different cutting stages, with a reduction in this number from the first to the fifth cutting stage, as well as to catalog the protein products of differentially expressed genes at different cutting stages. A list of proteins altered after the first cutting stage in each sugarcane cultivar may be highly useful for selecting cultivars for crosses in breeding programs. Cultivars with agronomic characteristics of interest and negligible changes in proteins related to the metabolic pathways essential for their performance may be selected.
Material and methods
Sugarcane plants
Approximately 10-month-old ‘RB966928’ plants at the first and fifth cutting stages were collected from the Nova Aralco Industrial (20°53′29.82″ S, 50°26′55.25″ W) farm in the state of São Paulo, Brazil. The first and fifth cutting stages were selected since high productivity is generally observed at the first cutting stage, while marked decrease in the agricultural productivity is evident at the fifth cutting stage. The sugarcane plants were cultivated in Argisol Dystrophic soil with low water availability and moderate cation-exchange capacity. The sugarcane plants were collected in close sessions at least 10 m away from the edges of the field. Based on leaf count using the Kuijper’s leaf numbering system, as described by Van Dillewijn (1952Van Dillewijn, C. (1952). Botany of sugarcane. Chronica Botanica. New York, NY: Stechert-Hafner. ), axillary buds from the fourth to ninth node were used to avoid a greater influence of auxins in the axillary buds near the stem apex. Axillary buds of the canes at the first and fifth cutting stages were individually planted in vermiculite in labeled 10 L trays, with 3 cm spacing between the plants, to initiate sprouting. The plants were irrigated every second day.
Sprouting occurred in the greenhouse at 22°C after 5 days. The axillary buds of each cutting age (first and fifth stages) were cut with a scalpel, instantly frozen in liquid nitrogen, and stored in an ultra-freezer at -80°C until use. Eight axillary buds were selected from each plant. At each cutting age (first and fifth stages), the axillary buds of three plants (biological triplicate) were sampled and divided into three aliquots (technical triplicate).
Protein extraction, quantification, and digestion
Total proteins were extracted from the axillary buds (200 mg; eight axillary buds) of each plant using the modified TCA-acetone method for sugarcane (Maranho et al., 2018Maranho, R. C., Benez, M. M., Maranho, G. B., Fernandes, V. N. A., Gonela, A., Mangolin, C. A., & Machado, M. F. P. S. (2018). Extraction of total protein from axillary buds of sugarcane (Saccharum spp.) for proteomics analysis. Sugar Tech, 20(1), 95-99. DOI: https://doi.org/10.1007/s12355-017-0520-z
https://doi.org/https://doi.org/10.1007/...
). Following extraction, the proteins were quantified by fluorimetry (Qubit Fluorometer 1.0; Invitrogen, Carlsbad, CA, USA) using the Qubit Protein Assay Kit (Invitrogen). The extracted proteins were pre-fractionated by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) (12% visualization gel and 5% stacking gel) for ~3 h at 200 V. The gel was then stained with 0.1% Coomassie Brilliant Blue R-250. SDS-PAGE verified the previously reported differences in protein expression in each sample and attested the protein extraction quality. The BenchMark Protein Ladder (10 to 220 KDa) was used to evaluate protein molecular weight.
Tryptic digestion followed the method described by Villén and Gygi (2008Villén, J., & Gygi, S. P. (2008). The SCX/IMAC enrichment approach for global phosphorylation analysis by mass spectrometry. Nature Protocols, 3(10), 1630-1638. DOI: https://doi.org/10.1038/nprot.2008.150
https://doi.org/https://doi.org/10.1038/...
) with slight modifications. Disulfide bonds were digested by incubation in dithiothreitol (DTT) solution (5 mM DTT and 50 mM NH4HCO3). Cysteine residues were alkylated by incubation in an alkylation solution (14 mM iodoacetamide and 50 mM NH4HCO3). The proteins were digested by the Trypsin/Lys-C Mix (Promega, Madison, WI, USA) at a final concentration of 20 ng µL-1 for 16h at 37°C.
Ultra-performance liquid chromatography (UPLC), mass spectrometry (MS), and bioinformatics
The protein digest was analyzed by UPLC on the ACQUITY UPLC M-Class System (Waters, Milford, MA, USA) coupled to a high-resolution time-of-flight mass spectrometer (Xevo G2, Waters) equipped with an electrospray ionization source. Mass spectrometry-based proteomics has become the tool of choice for identifying and quantifying the proteome of organisms (Karpievitch, Polpitiya, Anderson, Smith, & Dabney, 2010Karpievitch, Y. V., Polpitiya, A. D., Anderson, G. A., Smith, R. D., Dabney, A. R. (2010). Liquid chromatography mass spectrometry-based proteomics: biological and technological aspects. The Annals of Applied Statistics, 4(4), 1797-7823. DOI: https://doi.org/10.1214/10-AOAS341
https://doi.org/https://doi.org/10.1214/...
). The exceptional sensitivity and resolving power of today’s mass spectrometers allow for the detection of proteins and peptides at small amounts (Wither et al., 2016). Chromatographic separation was performed using the Acquity UPLC® M-Class HSS T3 Column (Waters, UK) (particle size, 1.8 µm; 300 µm × 150 mm) at a flow rate of 6 µL min.−1. The gradient mixture of solvents A (H2O with 0.1% formic acid; v:v) and B (acetonitrile with 0.1% formic acid; v/v) comprised 3% B 0-1 min., 40% B 1-80 min., 97% B 80-90 min., maintained at 97% B 90-97 min., 3% B 97-100 min., and maintained at 3% B 100-103 min. at 40°C. The capillary voltage was operated in the positive mode, at the following settings: 3.0 kV capillary voltage, 40 V sampling cone voltage, and 600 L h−1 desolvation gas at 400°C. Data were collected from m/z 50 to 2,000 via MSE acquisition; scan time was 0.5 X and ramp collision energy was 15-45 V.
Following UPLC-MS/MS, the data files (raw) were processed and analyzed using ProteinLynx Global ServerTM 3.0.3. Sequences were searched against the Viridiplantae and Saccharum taxonomy in the UniProtKB database (downloaded in April 2019). The following parameters were used for database searches: cleavage specificity: trypsin with 1 missed cleavage allowed; minimum fragment ion matches per peptide: 2; minimum fragment ion matches per protein: 5; minimum peptide matches per protein: 1; fixed modifier reagent: carbamidomethyl C; and variable modifier reagent: oxidation M.
Results and discussion
Bud sprouting
Five days after plantation in vermiculite, the sprouting rate of the axillary buds of ‘RB966928’ was higher at the first cutting stage (141/102, 72.3%) than at the fifth cutting stage (145/48, 26.9%).
‘RB966928’ proteome
The concentration of axillary bud proteins in the extract obtained using the modified TCA-acetone method was 747 µg mL−1 at the first cutting stage and 1.185 µg mL−1 at the fifth cutting stage.
SDS-PAGE showed differences in the protein expression profiles of the axillary buds between the first and fifth cutting stages (Figure 1). At both cutting stages, protein bands ranged between 120 and 25 kDa, and the regions with the highest protein amount and band intensity were 120 to 90 kDa, 60 to 50 kDa, 40 to 35 kDa, and 30 to 25 kDa.
Furthermore, 122 proteins were identified, of which respectively 97 and 95 were detected at the first and fifth cutting stages. Moreover, 27 (22.13% of the total proteome) (Table 1) and 25 (20.49% of the total proteome) (Table 2) proteins were exclusively detected at the first and fifth cutting stages, respectively, while 70 proteins were identified at both cutting stages (Figure 2).

The reduction in the number of proteins in the axillary buds was not significant between the first and fifth cutting stages of ‘RB966928’. Accordingly, difference in the proteome of the axillary buds between the first and fifth cutting stages was smaller in ‘RB966928’ than in ‘RB867515’. At the fifth cutting stage, the reduction in the number of proteins in the axillary buds was more remarkable in ‘RB867515’ than in ‘RB966928’ (Maranho et al., 2019Maranho, R. C., Benez, M. M., Maranho, G. B., Neiverth, A., Santos, M. F., Carvalho, A. L. O., ... Machado, M. F. P. S. (2019). Proteomic analysis of axillary buds of sugarcane at different cutting stages: evidence for alterations in axillary bud gene expression. Crop & Pasture Science, 70(7), 622-633. DOI: https://doi.org/10.1071/CP19115
https://doi.org/https://doi.org/10.1071/...
). In addition, difference in the number of proteins in the axillary buds that were exclusively detected at the first and fifth cutting stages was smaller in ‘RB966928’ than in ‘RB867515’. Thus, fewer proteins related to the metabolic pathways essential for performance were changed in ‘RB966928’ between the first and fifth cutting stages. Based on axillary bud gene expression, over 50% (62.5%) of the proteins were detected at both first and fifth cutting stages, whereas 46.4% were exclusively expressed at the first or fifth cutting stage.
The number of proteins detected in ‘RB966928’ in the present study was lower than that of protein detected in ‘RB867515’ in a previous study using 1DE-UPLC-ESI-Q-TOF (Maranho et al., 2019Maranho, R. C., Benez, M. M., Maranho, G. B., Neiverth, A., Santos, M. F., Carvalho, A. L. O., ... Machado, M. F. P. S. (2019). Proteomic analysis of axillary buds of sugarcane at different cutting stages: evidence for alterations in axillary bud gene expression. Crop & Pasture Science, 70(7), 622-633. DOI: https://doi.org/10.1071/CP19115
https://doi.org/https://doi.org/10.1071/...
). Although 1DE-UPLC-ESI-Q-TOF detected more proteins, the proteomic analysis of ‘RB966928’ axillary buds with tryptic digestion followed by UPLC coupled with high-resolution time-of-flight MS was faster, less labor intensive, and more cost-effective than the gel-based methodology adopted by Maranho et al. (2019).
Proteins exclusively detected in axillary buds of the first cut (plant cane) of the sugarcane cv. RB966928.
Proteins exclusively detected in axillary buds of the fifth cut (forth ratoon) of the sugarcane cv. RB966928.
Analysis of the 122 proteins detected at the first and fifth cutting stages showed that these proteins were associated with several cellular and metabolic processes, such as carbohydrate, lipid, and protein metabolism or biotic and abiotic stress response. Ribosomal proteins, transcription and elongation factors, cellular (cytoplasmic and vacuolar) components, molecular chaperones, histones, and other important peptides for axillary bud development were identified.
Differential proteomes at the first and fifth cutting stages
The 25 proteins detected exclusively at the first cutting stage serve diverse functions in biological processes, and many of these proteins (and polypeptides) are involved in fundamental metabolic pathways of plant development, including sprouting and budding. Five types of BiPs (BiP1, BiP2, Bip3, Bip4, and BiP5) were detected in the axillary buds of ‘RB966928’ at the first cutting stage, while only two BiPs (BiP1 and BiP2) were detected at the fifth cutting stage. BiPs are molecular chaperones of the endoplasmic reticulum (RE), which are involved in protein folding and maturation (Carvalho et al., 2014Carvalho, H. H., Silva, P. A., Mendes, G. C., Brustolini, O. J., Pimenta, M. R., Gouveia, B. C., ... Fontes, E. P. (2014). The endoplasmic reticulum binding protein BiP displays dual function in modulating cell death events. Plant Physiology, 164(2), 654-670. DOI: https://doi.org/10.1104/pp.113.231928
https://doi.org/https://doi.org/10.1104/...
). In the absence of BiPs, many secretory pathway proteins do not assume their active conformation and precipitate in the RE (Pobre, Poet, & Hendershot, 2019Pobre, K. F. R., Poet, G. J., & Hendershot, L. M. (2019). The endoplasmic reticulum (ER) chaperone BiP is a master regulator of ER functions: Getting by with a little help from ERdj friends.

https://doi.org/https://doi.org/10.1074/...
). Several studies have demonstrated the roles of BiPs in plant protection under various stress conditions, such as in stress attenuation in RE (Costa et al., 2008Costa, M. D., Reis, P. A., Valente, M. A., Irsigler, A. S., Carvalho, C. M., Loureiro, M. E., ... Fietto, L. G. (2008).

The chloroplast envelope membrane 70 kDa heat shock-related protein, chaperonin CPN60-1, mitochondrial precursor, cell division cycle protein 48 homolog, phenylalanine ammonia-lyase (PAL; EC 4.3.1.5), cytoplasmic phosphoglucomutase (cPGM; EC 5.4.2.2), sucrose synthase 2 (SuSy; EC 2.4.1.13), 5-methyltetrahydropteroyltriglutamate-homocysteine S-methyltransferase (MET6; 2.1.1.14), cytoplasmic aconitate hydratase (cACO; EC 4.2.1.3), pyruvate dehydrogenase E1 component beta subunit (PDH E1-β; EC 1.2.4.1), aminopeptidase 2 chloroplast precursor (LAPA2; EC 3.4.11.5), pyrophosphate-fructose 6-phosphate 1-phosphotransferase subunit beta (PFP-β; EC 2.7.1.90), phospholipase D precursor (PLD; EC 3.1.4.4), and serine-threonine kinase (MHK; EC 2.7.1) were also exclusively detected at the first cutting stage (Table 1).
Chaperonin CPN60-1, mitochondrial precursor, which was exclusively detected at the first cutting stage of ‘RB966928’, likely prevents the misfolding of polypeptides and promotes proper refolding and assembly of the unfolded polypeptides generated under stress conditions in the mitochondrial matrix. The chloroplast envelope membrane 70 kDa heat shock-related protein, which was also exclusively detected in the axillary buds of ‘RB966928’ at the first cutting stage, forms a complex of 11 heat-shock proteins (Hsps), which are induced under thermal stress. The Hsps are essential to protect cells from heat and various damages by normalizing cellular functions during recovery (Morimoto et al., 1994Morimoto, R. I., Jurivich, D. A., Kroger, P. E., Mathur, S. K., Murphy, S. P., Nakai, A., ... Sistonen, L. T. (1994). Regulation of heat shock gene transcription by a family of heat shock factors. In The biology of heat shock proteins and molecular chaperones (p. 417-455). New York, NY: Cold Spring Harbor Laboratory Press, Cold Spring Harbor.; Parsell & Lindquist, 1994Parsell, D. A., & Lindquist, S. (1994). Heat shock proteins and stress tolerance. In R. I. Morimoto, A. Tisslères, & C. Georgopoulos (Eds.), The biology of heat shock proteins and molecular chaperones (p. 457-494). New York, NY: Cold Spring Harbor Laboratory Press.; Nover et al., 1996Nover, L., Scharf, K. D., Gagliard, D., Vergne, P., Czarnecka, E., & Verner, W. B. (1996). The Hsf world: classification and properties of plant heat stress transcription factors. Cell Stress Chaperones, 1(4), 215-223. DOI: https://doi.org/10.1379/1466-1268
https://doi.org/https://doi.org/10.1379/...
). The exclusive detection of chloroplast envelope membrane 70 kDa heat shock-related protein and chaperonin CPN60-1, mitochondrial precursor in the axillary buds at the first cutting stage suggests that the absence of these proteins at the fifth cutting stage can lead to protein unfolding in the mitochondria and chloroplast, resulting in defects in photosynthesis and glycolysis.
The cell division cycle protein 48 homolog (a product of CDC48) is an essential protein for plant cell cycle progression and is a component of protein quality control in plant immunity against pathogen infection (Chisholm, Coaker, Day, & Staskawicz, 2006Chisholm, S. T., Coaker, G., Day, B., & Staskawicz, B. J. (2006). Host-microbe interactions: shaping the evolution of the plant immune response. Cell, 124(4), 803-814.

https://doi.org/https://doi.org/10.1126/...
). The CDC48 gene serves essential regulatory functions during development and possibly contributes to protein degradation through the ubiquitin proteasome system (UPS) or ER-associated protein degradation. Plants utilize UPS to facilitate cellular changes required to respond to and tolerate adverse growth conditions (Stone, 2019Stone, S. L. (2019). Role of the ubiquitin proteasome system in plant response to abiotic stress. International Review of Cell and Molecular Biology, 343, 65-110. DOI: https://doi.org/10.1016/bs.ircmb.2018.05.012
https://doi.org/https://doi.org/10.1016/...
). Exclusive detection of cell division cycle protein 48 homolog and ubiquitin-activating enzyme E1 1 in the axillary buds of ‘RB966928’ at the first stage suggests that defense responses to pathogens at the fourth ratoon may be weak, rendering the plants more vulnerable to pathogen attacks. Cell division cycle protein 48 homolog has been reported to regulate the turnover of immune receptors and act as a mediator of viral protein degradation (Bègue, Mounier, Rosnoblet, & Wendehenne, 2019Bègue, H., Mounier, A., Rosnoblet, C., & Wendehenne, D. (2019). Toward the understanding of the role of CDC48, a major component of the protein quality control, in plant immunity. Plant Science, 279(1), 34-44. DOI: https://doi.org/10.1016/j.plantsci.2018.10.029
https://doi.org/https://doi.org/10.1016/...
).
Similarly, exclusive detection of PAL at the first cutting stage may render the fourth ratoon more susceptible to pathogen attack and external injuries to the plant stem inflicted by abiotic and biotic factors. The production of phytoalexins and phenylpropanoids following fungal infection involves rapid induction of PAL (Ritte & Schulz, 2004Ritte, R. H., & Schulz, G. E. (2004). Structural bases for the entrance into the phenylpropanoid metabolism catalyzed by phenylalanine ammonia lyase PAL. The Plant Cell, 16(12), 3426-3436. DOI: https://doi.org/10.1105//tpc.104.025288
https://doi.org/https://doi.org/10.1105/...
). In tobacco, the suppression of PAL protein expression resulted in various phenotypes, including reduced growth, altered leaf shape, reduced pollen viability, and increased susceptibility to the pathogenic fungus Cercospora nicotianae (Eichel, Gonzalez, Hotze, Matthews, & Schroder, 1990). Plants with low PAL activity have thinned cell walls and reduced lignin content in the secondary xylem, which provides mechanical stiffness and strength to the stem, allows upward growth, and enables water and mineral transport through the vascular tissue under negative pressure without tissue collapse.
Strongly reduced growth, characterized by decreased fresh weight, shortened roots, and reduced seed production, has been reported in Arabidopsis lacking cPGM (Malinova et al., 2014Malinova, I., Kunz, H. H., Alseekh, S., Herbst, K., Fernie, A. R., & Gierth, M. (2014). Reduction of the cytosolic phosphoglucomutase in Arabidopsis reveals impact on plant growth, seed and root development, and carbohydrate partitioning. PLoS ONE, 9(11), 1-11. DOI: https://doi.org/10.1371/journal.pone.0112468
https://doi.org/https://doi.org/10.1371/...
). In our study, cPGM was detected in the axillary buds at the first cutting stage but not at the fifth cutting stage of ‘RB966928’. Thus, the absence of cPGM in the axillary buds of ‘RB966928’ at the fifth cutting stage may be associated with decreased agricultural productivity of sugarcane, with the plants becoming less robust and more susceptible to abiotic and biotic stresses with the advancement of cutting age.
Absence of other proteins including SuSy, MET6, cACO, LAPA2, PFP-β, PLD, and MHK in the axillary buds of ‘RB966928’ at the fifth cutting stage may reduce growth and decrease agricultural productivity of sugarcane at this stage. For instance, the products of sucrose cleavage by SuSy are available for many metabolic pathways, such as energy production, primary metabolite production, and complex carbohydrate synthesis. Plants with reduced SuSy activity have been shown to exhibit reduced growth, decreased starch content, limited cellulose or callose synthesis, reduced tolerance to anaerobic stress, and altered shoot apical meristem functions and leaf morphology. Meanwhile, plants overexpressing SuSy show augmented growth, increased xylem area and xylem cell wall thickness, and elevated cellulose and starch content, making SuSy a potent candidate for improving the agricultural traits of crops (reviewed by Stein & Granot, 2019Stein, O., & Granot, D. (2019). An overview of sucrose synthases in plants. Frontiers in Plant Science, 10(95), 1-14. DOI: https://doi.org/10.3389/fpls.2019.00095
https://doi.org/https://doi.org/10.3389/...
).
MET6 catalyzes the last step in L-methionine biosynthesis (Eichel et al., 1995Eichel, J., Gonzalez, J. C., Hotze, M., Matthews, R. G., & Schroder, J. (1995). Vitamin-B12-independent methionine synthase from a higher plant (Catharanthus roseus). Molecular characterization, regulation, heterologous expression, and enzyme properties. European Journal of Biochemistry, 230(3), 1053-1058. DOI: https://doi.org/10.1111/j.1432-1033.1995.tb20655.x.
https://doi.org/https://doi.org/10.1111/...
). Reduced aconitase activity led to a stunted phenotype at the early developmental stages of tomato (Lycopersicon pennellii) (Carrari et al., 2003Carrari, F., Nunes-Nesi, A., Gibon, Y., Lytovchenko, A., Loureiro, M. E., & Fernie, A. R. (2003). Reduced expression of aconitase results in an enhanced rate of photosynthesis and marked shifts in carbon partitioning in illuminated leaves of wild species tomato. Plant Physiology, 133(3), 1322-1335. DOI: https://doi.org/10.1104/pp.103.026716
https://doi.org/https://doi.org/10.1104/...
). Absence of LAPA2 in the axillary buds at the fifth cutting stage may also affect plant development, since LAPA2 is presumably involved in the processing and regular turnover of intracellular proteins.
Furthermore, PFP-β and PLD were important enzymes exclusively detected at the first cutting stage. PFP-β catalyze the first committing step of glycolysis, while PLD catalyzes phospholipid hydrolysis to produce phosphatidic acid, which often serves as a secondary messenger in intracellular signal transduction (Kolesnikov et al., 2012Kolesnikov, Y. S., Nokhrina, K. P., Kretynin, S. V., Volotovski, I. D., Martine, J., Romanov, G. A., & Kravets, V. S. (2012). Molecular structure of phospholipase D and regulatory mechanisms of its activity in plant and animal cells. Biochemistry, 77(1), 1-14. DOI: https://doi.org/10.1134/S0006297912010014
https://doi.org/https://doi.org/10.1134/...
). Absence of PFP-β may affect the equilibrium of carbon metabolism (Duan et al., 2016Duan, E., Wang, Y., Liu, L., Zhu, J., Zhong, H., Zhang, H., ... Wan, J. (2016). Pyrophosphate: fructose-6-phosphate 1-phosphotransferase (PFP) regulates carbon metabolism during grain filling in rice. Plant Cell Reports, 35(7), 1321-1331. DOI: https://doi.org/10.1007/s00299-016-1964-4
https://doi.org/https://doi.org/10.1007/...
). MHK is implicated in biotic stress and hormonal response (Taj, Agarwal, Grant, & Kumar, 2010Taj, G., Agarwal, P., Grant, M., & Kumar, A. (2010). MAPK machinery in plants: Recognition and response to different stresses through multiple signal transduction pathways. Plant Signal Behavior, 5(11), 1370-1378. DOI: https://doi.org/10.4161/psb.5.11.13020
https://doi.org/https://doi.org/10.4161/...
).
Furthermore, many proteins exclusively identified in the axillary buds of ‘RB966928’ at the fifth cutting stage are mainly linked to stress response and disease resistance. A series of proteins from the 14-3-3 (14-3-3-like family) protein family were exclusively detected at the fifth cutting stage. Seven 14-3-3 proteins were detected in the axillary buds at the fifth cutting stage, including 14-3-3-like protein A, 14-3-3-like protein GF14 lambda, 14-3-3-like protein GF14 kappa, 14-3-3-like protein 10, 14-3-3-like protein 4, 14-3-3-like protein GF14 nu, and 14-3-3-like protein GF14 upsilon. These seven 14-3-3-like family proteins, which were exclusively detected in the axillary buds of the fourth ratoon, are associated with the regulation of several important biochemical pathways and peroxide detoxification (Fulgosi et al., 2002Fulgosi, H., Soll, J., Faria Maraschin, S., Korthout, H. A., Wang, M., & Testerin, C. (2002). 14-3-3 Proteins and plant development. Plant Molecular Biology, 50(6), 1019-1029. DOI: https://doi.org/10.1023/A:1021295604109
https://doi.org/https://doi.org/10.1023/...
). Maranho et al. (2019Maranho, R. C., Benez, M. M., Maranho, G. B., Neiverth, A., Santos, M. F., Carvalho, A. L. O., ... Machado, M. F. P. S. (2019). Proteomic analysis of axillary buds of sugarcane at different cutting stages: evidence for alterations in axillary bud gene expression. Crop & Pasture Science, 70(7), 622-633. DOI: https://doi.org/10.1071/CP19115
https://doi.org/https://doi.org/10.1071/...
) detected 14-3-3-like proteins only in the fourth ratoon of ‘RB867515’. Different genes encoding the 14-3-3 proteins have been identified in various plant species (Camoni, Iori, Marra, & Aducci, 2000Camoni, L., Iori, V., Marra, M., & Aducci, P. (2000). Phosphorylation-dependent interaction between plant plasma membrane H(C)-ATPase and 14-3-3 proteins. Journal of Biology Chemistry, 275(14), 9919-9923. DOI: https://doi.org/10.1074/jbc.275.14.9919
https://doi.org/https://doi.org/10.1074/...
). For instance, 15 isoforms of 14-3-3-like proteins have been detected in Arabidopsis thaliana, 14 of which are labeled using the Greek letters (Camoni et al., 2000Camoni, L., Iori, V., Marra, M., & Aducci, P. (2000). Phosphorylation-dependent interaction between plant plasma membrane H(C)-ATPase and 14-3-3 proteins. Journal of Biology Chemistry, 275(14), 9919-9923. DOI: https://doi.org/10.1074/jbc.275.14.9919
https://doi.org/https://doi.org/10.1074/...
; Denison, Paul, Zupanska, & Ferl, 2011Denison, F. C., Paul, A. L., Zupanska, A. K., & Ferl, R. J. (2011). 14-3-3 proteins in plant physiology. Seminars in Cell Developmental Biology, 22(7), 720-727. DOI: https://doi.org/10.1016/j.semcdb.2011.08.006
https://doi.org/https://doi.org/10.1016/...
). In recent years, increasing evidence of the involvement of 14-3-3 proteins in various aspects of plant hormonal physiology have been accumulated. The review by Camoni, Visconti, Aducci, and Marra (2018Camoni, L., Visconti, S., Aducci, P., & Marra, M. (2018). 14-3-3 Proteins in plant hormone signaling doing several things at once. Frontiers in Plant Science, 9(297), 1-8. DOI: https://doi.org/10.3389/fpls.2018.00297
https://doi.org/https://doi.org/10.3389/...
) offers novel insights into the roles of 14-3-3 proteins in the regulation of hormonal signaling, biosynthesis, and transport. To date, however, no study has evaluated the roles of 14-3-3 proteins in sugarcane axillary buds.
Furthermore, glutathione-S-transferases (GSTs; EC 2.5.1.18), spermidine synthases (SPDSs; EC 2.5.1.16), and meiotic recombination protein DMC1 homolog were exclusively expressed at the fifth cutting stage, which play roles in both normal cellular metabolism and stress response.
GSTs involved in normal cellular metabolism and detoxification of a wide variety of xenobiotics, including herbicides, has been reported in plants (Mannervik & Danielson, 1988Mannervik, B., & Danielson, U. H. (1988). Glutathione transferases-structure and catalytic activity. CRC Critical Reviews in Biochemistry, 23(3), 283-337. DOI: https://doi.org/10.3109/10409238809088226
https://doi.org/https://doi.org/10.3109/...
). Early studies on the roles of GSTs in plant biotic stress showed that certain GST genes are specifically upregulated under microbial infection (Gullner, Komives, Király, & Schröder, 2018Gullner, G., Komives, T., Király, L., & Schröder, P. (2018). Glutathione S-transferase enzymes in plant-pathogen interactions. Frontiers in Plant Science, 9(1836), 1-19. DOI: https://doi.org/10.3389/fpls.2018.01836
https://doi.org/https://doi.org/10.3389/...
). Moreover, proteomic studies confirmed the accumulation of multiple GSTs in infected plants. The acknowledged roles of GSTs include detoxification through glutathione conjugation, oxidative stress relief, and hormone transport. Induction of the GST genes or elevation of the GST activity has often been observed in plants treated with beneficial microbes (bacteria and fungi), which induce a systemic resistance response to subsequent pathogen infections. A review by Kumar & Trivedi (2018Kumar, S., & Trivedi, P. K. (2018). Glutathione S-transferases: Role in combating abiotic stresses including arsenic detoxification in plants. Frontiers in Plant Science, 9(751), 1-9. DOI: https://doi.org/10.3389/fpls.2018.00751
https://doi.org/https://doi.org/10.3389/...
) provides updated information on the roles of GSTs in abiotic and biotic stresses, with an emphasis on their uptake, metabolism, and detoxification in plants. In addition, increased GST9 levels have been reported with aging, suggesting a role related to senescence. Thus, GSTs, which were exclusively detected in the axillary buds of the fourth ratoon (fifth cutting stage), may reflect a response to field-applied herbicides and/or subsequent pathogen infections with the advancement of cutting age.
SPDS was another protein exclusively detected in the axillary buds of ‘RB966928’ at the fifth cutting stage, and it is associated with stress response. According to Kasukabe et al. (2004Kasukabe, Y., He, L., Nada, K., Misawa, S., Ihara, I., & Tachibana, S. (2004). Overexpression of spermidine synthase enhances tolerance to multiple environmental stresses and up-regulates the expression of various stress-regulated genes in transgenic Arabidopsis thaliana. Plant Cell Physiology, 45(6), 712-722. DOI: https://doi.org/10.1093/pcp/pch083
https://doi.org/https://doi.org/10.1093/...
), spermidine plays important regulatory roles in stress signaling pathways, leading to increased stress tolerance in Arabidopsis thaliana. SPDSs are dimeric enzymes that share the fold of polyamine biosynthetic proteins (Sekula & Dauter, 2019Sekula, B., & Dauter, Z. (2019). Spermidine synthase (SPDS) undergoes concerted structural rearrangements upon ligand binding - A case study of the two SPDS isoforms from Arabidopsis thaliana. Frontiers in Plant Science, 10(555), 1-12. DOI: https://doi.org/10.3389/fpls.2019.00555
https://doi.org/https://doi.org/10.3389/...
). Polyamines have been implicated in a wide range of biological processes during plant growth and development, including senescence, environmental stress response, and fungal or viral resistance (Sawhney, Tiburcio, Altabella, & Galston, 2003Sawhney, K. R., Tiburcio, A. F., Altabella, T., & Galston, A. W. (2003). Polyamines in plants: An overview. Journal of Cell and Molecular Biology, 2, 1-12.). Pál et al. (2018Pál, M., Tajiti, J., Szalai, G., Peeva, V., Végh, B., & Janda, T. (2018). Interaction of polyamines, abscisic acid and proline under osmotic stress in the leaves of wheat plants. Scientific Reporter, 8(12839), 1-12. DOI: https://doi.org/10.1038/s41598-018-31297-6
https://doi.org/https://doi.org/10.1038/...
) detected high polyamine and proline levels under osmotic stress in wheat seedlings.
Meiotic recombination protein DMC1 homolog, also exclusively detected in the axillary buds of the fourth ratoon, has been identified as one of the two RecA homologs found in eukaryotic cells. DMC1 (disrupted meiotic cDNA) has been reported to play a central role in homologous recombination during meiosis through recruitment at the sites of programmed DNA double-strand breaks (DSBs). Szurman-Zubrzycka et al. (2019Szurman-Zubrzycka, M., Baran, B., Stolarek-Januszkiewicz, M., Kwasniewska, J., Szarejko, I., & Gruszka, D. (2019). The dmc1 mutant allows an insight into the DNA double-strand break repair during meiosis in barley (Hordeum vulgare L.). Frontiers in Plant Science, 10(761), 1-10. DOI: https://doi.org/10.3389/fpls.2019.00761
https://doi.org/https://doi.org/10.3389/...
) reported that DMC1 is essential for DSB repair, crossing-over, and proper chromosome disjunction during meiosis in barley. Although DMC1 is predominantly involved in meiosis, efficient mediation of mitotic recombination by rad51 and Dmc1 in yeast cells has been reported (reviewed by Neale & Keeney, 2006Neale, M. J., & Keeney, S. (2006). Clarifying the mechanics of DNA strand exchange in meiotic recombination. Nature, 442(7099), 153-158. DOI: https://doi.org/10.1038/nature04885
https://doi.org/https://doi.org/10.1038/...
). In our study, DMC1 was detected in the somatic cells of the axillary buds of ‘RB966928’at the fifth cutting stage. Occurrence of somatic recombination in sugarcane has been proposed by Augusto et al. (2017Augusto, R., Maranho, R. C., Mangolin, C. A., Bespalhok Filho, J. C., & Machado, M. F. P. S. (2017). Changes on microsatellites of expressed sequence tag of sugarcane (Saccharum spp.) during vegetative propagation. Genetics and Molecular Research, 16(1), 1-11. DOI: https://doi.org/10.4238/gmr16019519
https://doi.org/https://doi.org/10.4238/...
) to explain the loss of alleles and/or reduction in heterozygous phenotypes by vegetative propagation following each cutting stage in ‘RB72454’ and ‘RB867515’.
Overall, analysis of differential proteomes of the axillary buds of ‘RB966928’ at the first and fifth cutting stages revealed little changes in the number and composition of proteins essential for plant growth. The proteins exclusively detected at the first cutting stage prevent the misfolding of polypeptides and promote the proper refolding and assembly of the unfolded polypeptides generated under stress to tolerate adverse growth conditions. Furthermore, 40% of the proteins exclusively detected at fifth cutting stage are associated with stress responses and disease resistance. These results indicate that environmental stress, pathogen infection, and heavy metal contamination may reduce plant growth, rendering plants less robust and more susceptible to subsequent abiotic and biotic stresses and ultimately decreasing agricultural productivity of the sugarcane plantation with the advancement of cutting age.
Our findings suggest that if the expression of genes encoding proteins exclusive to the first cutting stage is induced at the fifth cutting stage, the decrease in bud sprouting and agricultural productivity of ‘RB966928’ with the advancement of cutting age may be attenuated. Listing of proteins that are altered from the first to fifth cutting stages in ‘RB968628’ may provide useful information for the selection of cultivars for crosses in breeding programs.
Conclusion
The present proteomic analysis in the regrowth cycles and axillary bud development of ‘RB966928’ significantly advanced our understanding of the biological processes linked to the reduction of agricultural productivity of sugarcane with the advancement of cutting age. Absence of proteins to tolerate adverse growth conditions at the fifth cutting stage may be related to reduced agricultural productivity, in addition to environmental stress, soil compaction, nutrient availability, cultural practices, and pests or pathogen attacks at different phenological stages of crops.
