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 improve plant growth under stress. Here present study, we isolated, identified, well-characterized eight drought-tolerant from rhizosphere that are tolerant 20% PEG-8000. These strains exhibited multiple 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 (IAA) production (14.3–46.2 of organic acids (72–178 ). Inoculation bacterial consortium ( Bacillus subtilis NM-2, Brucella haematophilum NM-4, cereus NM-6) significantly improved seedling vigor index (1009.2-1100) as compared non-inoculated stressed plants (630-957). Through rhizoscanning, efficiency was validated root parameters such length (17%), diameter, surface area (18%) all tested genotypes with respective treatments.

Plants face an array of environmental stresses, including both abiotic and biotic stresses. These stresses significantly impact plant lifespan reduce agricultural crop productivity. Abiotic such as ultraviolet (UV) radiation, high low temperatures, salinity, drought, floods, heavy metal toxicity, etc., contribute to widespread losses globally. On the other hand, those caused by insects, fungi, weeds, further exacerbate these challenges. stressors can hinder systems at various levels, molecular, cellular, development processes. To overcome challenges, multi-omics computational approaches offer a significant tool for characterizing plant’s biomolecular pool, which is crucial maintaining homeostasis signaling response changes.
