Abstract

Plant growth-promoting rhizobacteria (PGPRs) are an important group of microbial communities that exerts beneficial effects on plant growth upon root colonization. These are free-living bacteria that benefit the growth of plants by colonizing the rhizosphere. The PGPRs improve the plant growth mainly through two types of mechanisms either directly improving the plant growth or by indirect ways. Directly the PGPRs improve plant growth by enhancing the availability of nutrients like N, P, Fe etc. and producing different phytohormones. The PGPRs indirectly help in plant growth by antagonism against pathogens, competition with the pathogens and inducing the host resistance.
