The involvement of Pseudomonas bacteria in induced systemic resistance in plants (review).

This article reviews the most recent results of studies on the mechanism of induced systemic resistance (ISR) elicited in plants by non-pathogenic bacteria of the genus Pseudomonas. Several examples of Pseudomonas strains eliciting resistance against fungal phytopathogens in different species of crop plants are presented. Literature data dealing with bacterial elicitors and the effect of their interaction with plant receptors are quoted. Special focus is focused on the controversial issue of the correlation between the synthesis of pathogenesis-related proteins (PRs) and ISR.
