Soil salinity is a major abiotic stress in global agricultural productivity with an estimated 50% of arable land predicted to become salinized by 2050. Since most domesticated crops are glycophytes, they cannot be cultivated on salt soils. The use beneficial microorganisms inhabiting the rhizosphere (PGPR) promising tool alleviate various and represents strategy increase Increasing evidence underlines that PGPR affect plant physiological, biochemical, molecular responses stress. mechanisms behind these phenomena include osmotic adjustment, modulation antioxidant system, ion homeostasis, phytohormonal balance, nutrient uptake, formation biofilms. This review focuses recent literature regarding improve growth under salinity. In addition, very -OMICs approaches were reported, dissecting role modulating genomes epigenomes, opening up possibility combining high genetic variations plants action for selection useful traits cope conditions.

Salinization of land is globally increasing due to climate change, and salinity stress an important abiotic stressor that adversely affects agricultural productivity. In this study, we assessed a halotolerant endophytic bacterium, Pseudoxanthomonas sp. JBR18, for its potential as plant growth-promoting agent with multiple beneficial properties. The strain exhibited tolerance sodium chloride concentration up 7.5% in the R2A medium. vitro evaluation revealed JBR18 possessed proteolytic, protease (EC 3.4), cellulase 3.2.1.4) activities, well ability produce indole-acetic acid, proline, exopolysaccharides. Compared controls, co-cultivation Arabidopsis seedlings improved growth, rosette size, shoot root fresh weight, chlorophyll content under stress. Moreover, JBR18-inoculated showed lower levels malondialdehyde, reactive oxygen species, Na+ uptake into cells salt but higher K+. Additionally, inoculated delayed response time quantity salt-responsive genes RD29A, RD29B, RD20, RD22, KIN1 These effects suggest promising candidate mitigating negative impacts on growth. Our findings may assist future efforts develop eco-friendly strategies managing enhancing

SUMMARY Soil salinity severely threatens plant growth and crop yields. The utilization of PGPR is an effective strategy for enhancing salt tolerance, but the mechanisms involved in this process have rarely been reported. In study, we investigated effects Bacillus subtilis CNBG‐PGPR‐1 on improving tolerance elucidated molecular pathways involved. results showed that significantly improved cellular homeostasis photosynthetic efficiency leaves reduced ion toxicity osmotic stress caused by tomato. Transcriptome analysis uncovered enhanced through activation complex pathways, with hormone signal transduction playing important role. Comparative pharmacological experiments confirmed ethylene pathway was closely related to beneficial effect tolerance. Furthermore, found methionine, a precursor synthesis, accumulated response Exogenous L‐methionine largely mimicked activated expression pathway‐related genes, indicating induces methionine accumulation regulate Finally, salt‐induced ROS activating scavenger‐encoding mainly GSH metabolism POD‐related which were also linked metabolism. Overall, our studies demonstrate CNBG‐PGPR‐1‐induced key regulator scavenging, providing novel understanding mechanism microbes improve

Drought is a major challenge for agriculture worldwide, being one of the main causes losses in plant production. Various studies reported that some soil's bacteria can improve tolerance to environmental stresses by enhancement water and nutrient uptake plants. The Atacama Desert Chile, driest place on earth, harbors largely unexplored microbial richness. This study aimed evaluate ability various

The application of plant growth-promoting rhizosphere (PGPR) and Gamma-polyglutamic acid (γ-PGA) has a potential role in improving tolerance under abiotic stress, while their combined effects remain largely unexplored. This study aimed to evaluate the joint PGPR γ-PGA on maize growth microbial communities salt stress. A pot experiment consisting two strain treatments (CK, M10), (γ0, γ1) (S1, S2) was performed for this purpose. results showed that S1 treatment, M10 could increase height, leaf area dry weight by 11.27%, 36.45% 8.39% respectively (P<0.05). Under S2 corn 34.46%, 142.80% 55.81% In addition, reduced Na+ content leaves 59.43% significantly increased proportion bacterial Firmicutes (mainly including Bacillus_firmus_g_Bacillus Bacillus_selenatarsenatis) soil. Leaf-Na+ (P<0.001), root-K+ (P<0.01), leaf-total phosphorus (P<0.05), root-total (P<0.01) electron transfer rate had significant effect changes structure community. interaction network improve numbers were directly related factors. not only demonstrated benefits but also provided insights into mechanism from perspective community changes.

Biochar is considered one of the most promising long-term solutions for soil quality improvement, representing an ideal environment microorganisms' immobilization. Hence there a possibility to design microbial products formulated using biochar as solid carrier. The present study was aimed at development and characterization Bacillus-loaded be applied amendment. producing microorganism Bacillus sp. BioSol021 evaluated in terms plant growth promotion traits, indicating significant potential production hydrolytic enzymes, indole acetic acid (IAA) surfactin positive tests ammonia 1-aminocyclopropane-1-carboxylic (ACC) deaminase production. Soybean characterised physicochemical properties evaluate its suitability agricultural applications. experimental plan immobilisation included variation concentration cultivation broth adhesion time, while amendment effectiveness during maize germination. best results seed germination seedling were achieved by applying 5% 48 h procedure. Germination percentage, root shoot length vigour index significantly improved when Bacillus-biochar compared separate treatments including broth. indicated synergistic effect on promotion, pointing out this proposed multi-beneficial solution application practices.
