Mycorrhizal helper bacteria: Sustainable approach

Abstract

Microorganisms in rhizosphere play an important role in soil processes that determine plant and soil productivity. Tremendous efforts have been made to explore mycorrhizal diversity along with benign role of bacterial population in soil habitats to understand the successful functioning of extraneous microbial bio-inoculants (AMF/PGPR) and their influence on soil health. Improvement in agricultural sustainability requires optimal use and management of soil fertility and soil physical property and relies on soil biological processes and soil biodiversity. Plants play an important role in selecting and enriching the type of microbes by the constituents of their root exudates. The mycorrhizal and bacterial community develops in the rhizosphere which is a result of diverse nature and concentration of organic constituents of exudates and the corresponding ability of them to utilize these as sources of energy. Therefore, rhizosphere microbial community has an efficient system for uptake and catabolism of organic compounds present in root exudates and further transportation in plants mediated through mycorrhizal helper bacteria.
