Plant growth promoting rhizobacteria as alternative to chemical crop protectors from pathogens (review)

Abstract

The review analyses data on physiological and biochemical influence of rhizospheric and endophytic plant growth promoting rhizobacteria (PGPR) on induced the mechanisms of resistance of plants and the possibility of their using in agricultural for to protect crop from pathogens and phytophages. Resistance of plants promoted by PGPR due to their endosymbiotic interrelationships is directly achieved by producing peptide antibiotics and hydrolases of chitin and glucan and also because plants form their own system of induced resistance, accompanied by changes in the balance of defensive proteins, phytohormones, and pro-/antioxidant status.
