Unlocking the Secrets of Rhizosphere Microbes: A New Dimension for Agriculture

Rhizospheric microbes help plants to acquire and assimilate nutrients, improve soil texture and modulate extracellular molecules. Rhizosphere bacteria regularly encounter a copious number of variables, such as temperature, pH, nutrients, pest resistance mechanisms, etc. The extracellular concentrati...

Summary:Rhizospheric microbes help plants to acquire and assimilate nutrients, improve soil texture and modulate extracellular molecules. Rhizosphere bacteria regularly encounter a copious number of variables, such as temperature, pH, nutrients, pest resistance mechanisms, etc. The extracellular concentration of chemical messengers fabricated by plant growth promoting bacteria (PGPB) in a system is directly proportional to the bacterial population. To dwindle the use of chemically synthesised pesticides, plant growth-promoting rhizobacteria (PGPR) are new arsenals of imperishable agricultural practises for managing plant pathogens and resistance. This review aims to harness the rhizosphere milieu to raise climate smart crops. The PGPB mediated hormonal control of plant stress management pathway could be potentially modified for the benefit of plants. Nutrient solubilisation strengthens the rhizomicrobiome for phytoremediation and pathogen control. Quorum sensing as well as the role of enzymes and siderophores in rhizo-microbiome has been discussed. With advent of metagenomics, the understanding of soil microbiome ecology has acquired new dimensions and has enabled us to modify the microbiome for sustainable agriculture and enhanced productivity.
