Eco-friendly plant growth promoting rhizobacteria for crop improvement

Abstract

Soil microorganisms are important in the geobiochemical cycles of inorganic and organic nutrients in the soil and maintenance of soil health and quality. The rhizosphere of plants is inhabited by complex and dynamic communities of microorganisms, notable among which are plant growth-promoting and soil-supporting bacteria. Soil-plant-rhizobacteria interactions are complex, and there are many ways in which the outcome can influence the plant health and productivity. The PGPRs are also potential biocontrol agents of several soilborne plant pathogens. The rhizosphere provides the frontline defense of roots against attack by pathogens. The present review provides the interaction of PGPR with other microbes in the rhizosphere, thus contributing for sustainable crop production.
