(Please consult a last issue of Acta Botanica Brasilica for layout and style)
All manuscripts must follow these guidelines: the text should be in Times New Roman font, size 12, double-spaced throughout and with 25 mm margins; the paper size should be set to A4 (210 x 297 mm). All pages should be numbered sequentially. Each line of the text should also be numbered, with the top line of each page being line 1. For text files .doc, .docx and .rtf are the only acceptable formats. Files in Adobe® PDF format (.pdf files) will not be accepted. When appropriate, the article file should include a list of figure legends and table heads at the end. This article file should not include any illustrations or tables, all of which should be submitted in separate files.Do not include field code either.
The first page should state the type of article (Original Article, Review, Viewpoint, Method, Short communication or MDD) and provide a concise and informative full title followed by the names of all authors. Each name should be followed by the Orcid number an identifying superscript number (1, 2, 3 etc.) associated with the appropriate institutional address to be entered further down the page. Only one corresponding author should be indicated with an asterisk and should always be the submitting author. The institutional address(es) of each author should be listed next, each address being preceded by the superscript number where appropriate. The address must be synthetic and in English with institution, postal code, city, state and country. Do not translate laboratory, department and university. Titles and positions should not be mentioned. This information is followed by the e-mail address of the corresponding author.
The second page should contain a structured Abstract not exceeding 200 words in a single paragraph without references. The Abstract should outline the essential content of the manuscript, especially the results and discussion, highlighting the relevance of main findings.
The Abstract should be followed by between five and ten Key words. Note that essential words in the title should be repeated in the key words.
Original articles should be divided into sections presented in the following order:
Title page
Abstract
Introduction
Materials and methods
Results
Discussion
Acknowledgements
References
Tables and Figure legends
Supplementary Data (if applicable)
Material and methods and Results should be clear and concise. The Discussion section should avoid extensive repetition of the results and must finish with some conclusions. This section can be combined with results (Results and discussion), however, we recommend authors consult the Editoral Board for a previous evaluation.
Plant names must be written out in full in the abstract and again in the main text for every organism at first mention but the genus is only needed for the first species in a list within the same genus (e.g. Hymenaea stigonocarpa e H. stilbocarpa). The authority (e.g., L., Mill., Benth.) is required only in Material and Methods section. Use The International Plant Names Index (www.ipni.org) for correct plants names. Cultivars or varieties should be added to the scientific name (e.g. Solanum lycopersicum 'Jumbo'). Authors must include in Material and Methods a reference to voucher specimen(s) and voucher number(s) of the plants or other material examined.
Abbreviations must be avoidexceptfor usual cases (see recent issues) and all terms must be written out in full when used to start a sentence. Non-conventional abbreviations should be spelled out at first mention.
Units of Measurement. Acta bot. bras. adopts the Systéme International d'Unités (SI). For volume, use the cubic metre (e.g. 1 × 10–5 m3) or the litre (e.g. 5 μL, 5 mL, 5 L). For concentrations, use μM, μmol L–1 or mg L–1. For size and distance use meters (cm, mm, um, etc) and be consistent in the manuscript.
Numbers up to nine should be written out unless they are measurements. All numbers above ten should be in numerals unless they are starting sentences.
Citations in the text should take the form of Silva (2012) or Ribeiro & Furr (1975) or (Mayer & Wu 1987a; b; Gonzalez 2014; Sirano 2014) and be ordered chronologically. Papers by three or more authors, even on first mention, should be abbreviated to the name of the first author followed by et al. (e.g. Simmons et al. 2014). If two different authors have the same last name, and the article have the same year of publication, give their initials (e.g. JS Santos 2003). Only refer to papers as 'in press' if they have been accepted for publication in a named journal, otherwise use the terms 'unpubl. res.', giving the initials and last name of the person concerned (e.g., RA Santos unpubl. res.).
References should be arranged alphabetically based on the surname of the author(s). Where the same author(s) has two or more papers listed, these papers should be grouped in year order. Letters 'a', 'b', 'c', etc., should be added to the date of papers with the same citation in the text. Please provide DOI of ‘in press’ papers whenever possible.
For papers with six authors or fewer, please give the names of all the authors. For papers with seven authors or more, please give the names of the first three authors only, followed by et al.

Acknowledgements should be preferably in fewer than 80 words. Be concise: “we thank…” is preferable to “The present authors would like to express their thanks to…”. Funding information should be included in this section.
The following example should be followed:
We acknowledge the Center of Microscopy (UFMG) for providing the equipment and technical support for experiments involving electron microscopy. We also thank J.S. Santos for assistance with the statistical analyses. This work was supported through a research grant from the Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq (ID number).
For SHORT COMMUNICATIONS note that the editorial guidelines applying to original papers must also applying here. In general, the difference between original papers and short communications is the lack of subsections in the text and limited space for illustrations in the latter. Figures and tables can be present, assuming that the overall size of the manuscript does not exceed the five printed page limit (supplementary material can be added). The abstract (as described for original articles) must be followed by a “running text” (a single section, without subheadings), followed by the acknowledgments and references.
