Shekhar Jain, Anookul Vaishnav, Amrita Kasotia, Sarita Kumari and Devendra Kumar Choudhary

Plant growth-promoting bacteria (PGPB) are microorganisms that exert benign effects on plants and regulate plant growth. They are the denizen of rhizosphere and along with it form epiphytes (on plant surface) and endophytes (inside plant tissues) that define all the regulatory processes of plants including resistance and tolerance against biotic and abiotic stresses. Several PGPB induce resistance against pathogens by eliciting physiological changes in plants together with tolerance to drought, salt, and other environmental factors. Bacteria elicited induced ...
