Mitigation of water scarcity with sustained growth of Rice by plant growth promoting bacteria.

ABSTRACT: Climate change augments the risk to food security by inducing drought stress and a drastic decline in global rice production. Plant growth-promoting bacteria (PGPB) have been known to improve plant growth under drought stress. Here in the present study, we isolated, identified, and well-characterized eight drought-tolerant bacteria from the rice rhizosphere that are tolerant to 20% PEG-8000. These strains exhibited multiple plant growth-promoting traits, i.e., 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity, exopolysaccharide production, phosphate (P)-solubilizing activity (51-356 µg ml^-1), indole-3 acetic acid (IAA) production (14.3-46.2 µg ml^-1), and production of organic acids (72-178 µg ml^-1).
