Abiotic stresses adversely affect rice yield and productivity, especially under the changing climatic scenario. Exposure to multiple abiotic stresses acting together aggravates these effects. The projected increase in global temperatures, rainfall variability, and salinity will increase the frequency and intensity of multiple abiotic stresses.

- The study compared the responses of a drought-susceptible mustard genotype (Pusa Karishma LES-39) and a drought-tolerant genotype (NPJ-124) to rhizobacterial inoculation during water deficit stress, highlighting how inoculants affected their biochemical and physiological traits.
- Inoculation led to improved root and shoot dry weight for both genotypes, but the drought-susceptible genotype showed greater overall benefits in enzymes and other parameters, including reduced starch and increased antioxidative activity.
- The drought-susceptible genotype exhibited enhanced expression of certain drought stress-responsive genes (DREB2 and DREB1-2) after inoculation, suggesting that the ABA-independent pathway
