Results showed that effectively managed moderate salinity (50 NaCl) by maintaining succulence, weight ratios, biomass allocation patterns both shoot root with minimal reduction dry biomass. However, high (100 remarkably declined all growth parameters. The accumulated more Na + Cl − , while less K as compared to control. Consequently, osmotic potentials leaf decreased salinity, which was corroborated amount proline soluble sugars.

Soil salinity is the major abiotic stress that disrupts nutrient uptake, hinders plant growth, and threatens agricultural production. Plant growth-promoting rhizobacteria (PGPR) are most promising eco-friendly beneficial microorganisms can be used to improve responses against biotic stresses. In this study, a previously identified B. thuringiensis PM25 showed tolerance up 3 M NaCl. The Halo-tolerant Bacillus demonstrated distinct enhance activities under stress. Antibiotic-resistant Iturin C ( ItuC ) bio-surfactant-producing sfp srfAA genes confer stresses were also amplified in PM25. Under stress, physiological molecular processes followed by over-expression of stress-related (APX SOD) results detected inoculation substantially improved phenotypic traits, chlorophyll content, radical scavenging capability, relative water content significantly increased antioxidant enzyme levels inoculated maize as compared uninoculated plants. addition, PM25-inoculation dramatically soluble sugars, proteins, total phenols, flavonoids reduced oxidative burst Furthermore, PM25-inoculated plants had higher compatible solutes than controls. current plays an important role reducing influencing defense systems genes. These findings suggest multi-stress tolerant could growth mitigating salt which might innovative tool for enhancing yield productivity.
