Schematic graph of the interaction mechanism between the lectin and Abu shows the relation of these molecules and the ISR in leguminous. The figures inside the frames represent the molecule forms that occur in high concentration during the plant ontogeny. (●) represents the Abu concentration during the seeding as reported by Rozan et al.; (■) refers to the lectin concentration determined by Da Silva et al.; and (▲) gives the concentration of compounds related to pathogens response and stress events in accord to Boege K & Marquis R J.
