Resumen o descripción
"Currently many studies have been made on the use of natural products as substitutes for chemical control, due to possible ecological and economic advantages that many of these compounds offer, especially in crop protection. Many natural products have compounds with the ability to stimulate defense mechanisms in plants; defense reactions to the nearest tissue infection are restricted in some cases, resistance induction is associated to the expression of some defense genes, such as those coding for proteins linked to the pathogenesis. For example phenylalanine ammonia lyase and synthesis phytoalexins are highly toxic compounds to the pathogen. On the other hand the increase of peroxidases, can increase the mechanical strength of the host cells walls, inhibiting or possibly restricting a pathogen invasion. The objective of this study was to compare the effect of the PGPR consortium at 6, 12 and 24 hours after application, against Fusarium oxysporum and Rhizoctonia solani, determined by leaf tissue, quantification of protein and enzyme activities of phenylalanine ammonia lyase and peroxidase. The results presented in this paper clearly demonstrated the potential of the PGPR consortium strains to activate resistance against F. oxysporum or R. solani."
