The effect of endophytic and rhizospheric bacteria was studied on salt stress in a local paddy rice (Oryza sativa L.) variety GJ-17. Plants inoculated with endophytic bacterium Pseudomonas pseudoalcaligenes showed significantly higher concentration of glycine betaine-like quaternary compounds and higher shoot biomass at lower salinity levels. While at higher salinity levels, mixture of both P. pseudoalcaligenes and Bacillus pumilus showed better response against the adverse effects of salinity. However, accumulation of proline showed an opposite trend against plant growth promoting rhizobacteria (PGPR) treatment in salinity stress. Proline concentration increased with salinity but decreased in plants inoculated with either of the PGPRs or mixture of both P. pseudoalcaligenes and B. pumilus. The present study shows that inoculation of paddy rice (Oryza sativa L.) with a mixture of endophytic and rhizospheric bacteria could serve as a useful tool for alleviating salinity stress.
