Salt stress is a major global issue that negatively affects plant growth and physiological processes. Plant growth-promoting rhizobacteria (PGPR) are known to alleviate salt promote growth. This study aimed isolate characterize salt-tolerant PGPR from salinity-affected soils in Tamil Nadu, India, assess their potential enhance tolerance sesame (Sesamum indicum L.). Salt-tolerant were isolated screened for traits. One isolate, designated PAS1, demonstrated significant capabilities, including the production of indole-3-acetic acid (IAA; 48.56 μg ml-1), siderophore (89.20 ± 0.65%), phosphate solubilization (7.8 mm zone clearance), ammonia, hydrogen cyanide (HCN) production. PAS1 was identified as Bacillus flexus. Sesame plants inoculated with B. flexus grown under different concentrations (0, 100, 200 mM NaCl) 45 days. Inoculation significantly improved biochemical parameters stress, increased chlorophyll content (4.4 mg g-1), proline (0.0017 soluble sugars (61.34 amino acids (1.10 proteins (3.31 g-1). Additionally, antioxidant enzyme activities enhanced, indicated by DPPH scavenging activity (60.25%), superoxide dismutase (231.29 U g-1 protein), peroxidase (6.21 catalase (3.38 reduction malondialdehyde (23.32 μmol The demonstrates inoculation can effectively improve stress. These findings suggest halo-tolerant strains like could serve promising biofertilizers crop productivity salt-affected agricultural soils.

Salicylic acid (SA) plays a crucial role in regulating plant growth and development mitigating the negative effects of various stresses, including salinity. In this study, effect 50 μM SA on physiological biochemical parameters wheat plants under normal stress conditions was investigated. The results showed that 28th day growing season, pretreatment continued to stimulate plants. This evident through an increase shoot length leaf area, with regulation blade width playing significant effect. Additionally, improved photosynthesis by increasing content chlorophyll (Chl a) carotenoids (Car), resulting increased TAP (total amount pigments) index leaves. Furthermore, treatment led balanced levels reduced glutathione (GSH) oxidized (GSSG) leaves, accompanied slight but accumulation ascorbic (ASA), hydrogen peroxide (H2O2), proline, activation reductase (GR) ascorbate peroxidase (APX). Exposure salt for 28 days resulted reduction photosynthetic pigments, GSH ASA It also H2O2 proline GR APX. However, exhibited long-term growth-stimulating protective conditions. significantly mitigated impacts salinity accumulation, lipid peroxidation, H2O2. salinity-induced depletion levels, which associated modulation APX activities. small-scale field experiments conducted natural conditions, pre-sowing seed main indicators grain yield essential amino acids grains. Thus, can be considered effective approach providing prolonged protection improving quality.
