Interaction of Rhizobacteria with Soil Microorganisms: An Agro-Beneficiary Aspect

Abstract

The plant growth-promoting rhizobacteria (PGPR) have been extensively used for the plant growth enhancement in agriculture and horticulture in several ways. Several PGPR formulations with modified technology are nowadays available for increasing agriculture production. Microbial communities are associated with plants that are highly diverse and specifically associated with types of plant species, which controls plant health via several mechanisms. Recent evidence supports the fact that plants under attack recruit beneficial microbes into their rhizosphere, which supports plant growth via various direct and indirect mechanisms. It is essential to develop proper understanding of interactions between host plants and associated microbial community to elucidate their role in crop improvement. The research is being focused on establishing the facts about their mutualistic interactions and diversity, so they can be exploited for biocontrol and growth promoters. Efforts are still needed to know more about plant microbiomes as a system that can further help in analyzing the complex interactions.
