This can be explained by the absence of the specific elicitor phytoalexin
for the gene expression
of these plants, since it is of secondary metabolism products that is required phenotypic changes
elicited by the action of biotic or abiotic agents.
leia-se:
This gap can be explained by the lack either elicitors, biotic or abiotic, as specific genes that
regulates the expression/activation of components of the metabolic pathways necessary for
obtaining the phytoalexin molecule.

resistant cultivars.

Once they are no pathogenic organisms, their mechanism of action is the induced systemic
resistance, not causing symptoms such as necrosis and activating the defense response of plants
such as the production of PRPs and phytoalexins.

Because these are compounds that are extracted from plants, they can present phytoalexins,
which contribute to an increased expression of these compounds in plants used in the study.

elicitors for each species needs also more studies to clarify what is the secondary metabolism
product and metabolism elicitors.
