Introduction The ongoing global expansion of salt-affected land is a significant factor, limiting the growth and yield crops, particularly rice ( Oryza sativa L). This experiment explores mitigation salt-induced damage in (cv BRRI dhan100) following application plant growth-promoting rhizobacteria (PGPR). Methods Rice seedlings, at five- six-weeks post-transplanting, were subjected to salt stress treatments using 50 100 mM NaCl seven-day intervals. Bacterial cultures consisting endophytic PGPR Bacillus subtilis B. aryabhattai ) an epiphytic administered three critical stages: transplantation 42-day-old vegetative stage five weeks post-transplantation, panicle initiation seven post-transplantation. Results Salt induced osmotic stress, ionic imbalances, oxidative plants, with consequent negative effects on growth, decrease photosynthetic efficiency, changes hormonal regulation, along increased methylglyoxal (MG) toxicity. treatment alleviated salinity by improving antioxidant defenses, restoring equilibrium, enhancing water balance, increasing nutrient uptake, attributes, bolstering hormone synthesis, MG detoxification. Discussion These findings highlight potential bolster physiological biochemical functionality serving as effective buffer against stress–induced damage. showed greatest benefits, while both had commendable mitigating plants.

Salt stress is considered to be one of the major abiotic stresses influencing rice growth and productivity. To improve crop productivity in saline soils, it essential choose a suitable variety for mitigating salt gain deep understanding underlying mechanisms. The current study explored tolerance mechanism wild 'HD96-1 (salt resistive)' conventional 'IR29 sensitive)' by evaluating morph-physiological, transcriptomic, metabolomic approaches. Physiological data indicated that HD96-1 had higher chlorophyll content, photosynthetic efficiency, more stable Na+/K+, less H₂O₂, lower electrolyte leakage under compared with IR29. Transcriptomic showed expression NHXs IR29 was significantly down-regulated stress, leading large accumulation Na⁺ cytoplasm, CHLH, PORA, PORB down-regulated, inhibiting synthesis. maintained balance K⁺ increasing NHX4, there no significant change genes related synthesis, which made resistant than In addition, inhibited excessive synthesis hydrogen peroxide (H₂O₂) alleviated oxidative damage down-regulating ACX4 stress. promoted isoleucine up-regulating branched-chain amino acid aminotransferase 2 4 might promote raffinose stachyose gene galactitol synthase 2, which, turn, osmotic pressure relieved We also found inhibition photosynthesis light-harvesting chromophore protein complex (LHCH II)-related reducing glucose metabolites, respectively. enhances regulating C2H2 bHLH153 transcription factors.

The growing issue of salinity is a significant threat to global agriculture, affecting diverse regions worldwide. Nitric oxide (NO) serves as an essential signal molecule in regulating photosynthetic performance under physiological and stress conditions. present study reveals the protective effects different concentrations (0–300 µM) sodium nitroprusside (SNP, donor NO) on functions main complexes within apparatus maize (Zea mays L.

Mitigation of salt stress in Sorghum bicolor L. by the halotolerant endophyte Pseudomonas stutzeri ISE12

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Increasing soil salinity, exacerbated by climate change, threatens seed germination and crop growth, causing significant agricultural losses. Using bioinoculants based on halotolerant plant growth-promoting endophytes (PGPEs) in modern agriculture is the most promising sustainable method for supporting growth under salt-stress conditions. Our study evaluated efficacy of Pseudomonas stutzeri ISE12, an endophyte derived from extreme halophyte Salicornia europaea , enhancing salinity tolerance sorghum ( Sorghum bicolor L.). We hypothesized that P. ISE12 would improve salt to with extent increase depending genotype’s sensitivity stress. Experiments were conducted two genotypes differing (Pegah - tolerant, Payam sensitive), which inoculated a selected bacterium at different concentrations (0, 100, 150, 200 mM NaCl). For germination, we measured percentage index, mean time, vigor, shoot root length seedlings, fresh dry weight. In pot experiments, assessed number leaves, leaf area, specific weight ratio, relative weight, plantlet length, proline hydrogen peroxide concentrations, peroxidase enzyme activity. demonstrated inoculation significantly enhanced both genotypes. The salinity-sensitive genotype (Payam) responded better bacterial during early seedling stages, showing approximately 1.4 1.8 times greater improvement than salinity-tolerant (Pegah). also displayed performance stage, between 1.1 2.6 higher Pegah. Furthermore, reduced peroxide, activity, levels These reductions notably more pronounced Payam, up 1.5, 1.3, 1.5 results highlight alleviating oxidative stress reducing energy expenditure defense mechanisms sorghum, particularly benefiting salt-sensitive findings potential as valuable bioinoculant promote saline
