With climate change, the frequency of regions experiencing water scarcity is increasing annually, posing a significant challenge to crop yield. Barley, staple consumed and cultivated globally, particularly susceptible detrimental effects drought stress, leading reduced yield production. Water adversely affects multiple aspects barley growth, including seed germination, biomass production, shoot root characteristics, osmotic status, photosynthesis, induces oxidative resulting in considerable losses grain its components. In this context, present review aims underscore importance selecting drought-tolerant genotypes utilizing bio-inoculants constructed from beneficial microorganisms as an agroecological approach enhance growth production resilience under varying environmental conditions. Selecting with robust physiological agronomic tolerance can mitigate diverse Plant Growth Promoting Rhizobacteria (PGPR) play crucial role promoting plant through nutrient solubilization, nitrogen fixation, phytohormone exopolysaccharide secretion, enzyme activity enhancement, many other mechanisms. Applying containing PGPR, improves barley's thereby minimizing caused by scarcity.

Abstract Globally, drought stress poses a significant threat to crop productivity. Improving the tolerance of crops with microbial biostimulants is sustainable strategy meet growing population’s demands. This research aimed elucidate biostimulants’ (Plant Growth Promoting Rhizobacteria) role in alleviating oil-seed crops. In total, 15 bacterial isolates were selected for and screened plant growth-promoting (PGP) attributes like phosphate solubilization production indole-3-acetic acid, siderophore, hydrogen cyanide, ammonia, exopolysaccharide. describes two PGPR strains: Acinetobacter calcoaceticus AC06 Bacillus amyloliquefaciens BA01. The present study demonstrated that these strains (AC06 BA01) produced abundant osmolytes under osmotic stress, including proline (2.21 1.75 µg ml − 1 ), salicylic acid (18.59 14.21 trehalose (28.35 22.74 mg FW) glycine betaine (11.35 7.74 g ) respectively. BA01 further evaluated their multifunctional performance by inoculating Arachis hypogaea L. (Groundnut) mild severe regimes (60 40% Field Capacity). Inoculation displayed distinct osmotic-adjustment abilities groundnut, such as growth parameters, biomass, photosynthetic pigments, relative water content, proline, soluble sugar respective control during drought. On other hand, sensitivity indexes electrolyte leakage malondialdehyde (MDA) contents decreased well cooperatively conferred induced alterations indicators catalase (CAT), ascorbate peroxidase (APX), superoxide dismutase (SOD). Thus, sp. can be considered osmolyte producing simultaneously induce metabolic changes groundnuts stress.

Plant growth-promoting rhizobacteria (PGPRs) represent a promising strategy for enhancing plant resilience and yields under drought-stress conditions. This study isolated characterized PGPR from wheat rhizosphere soil in Egypt. Four strains were evaluated an array of traits, including IAA production, biofilm formation, siderophore nitrogen fixation, ACC deaminase activity, phosphate solubilization, antagonistic potential. Molecular identification via 16S rRNA sequencing classified three isolates (MMH101, MMH102, MMH103) within the Bacillus genus one isolate (MMH104) as Myroides sp. Greenhouse experiments examined effects inoculation on drought-stressed Egyptian cultivar, Gimmeza-9. Wheat plants inoculated with showed dramatic improvements growth parameters stress tolerance indicators compared to non-inoculated controls when subjected 10-day drought period, rugosus (MMH101) resulting increases 61.8% fresh biomass, 77.2% dry 108.5% shoot length, 134.9% root length. treatments also elevated chlorophyll proline content while reducing malondialdehyde levels. The findings demonstrate effectiveness morphology, physiology, wheat. Isolated hold promise biofertilizers improving cereal productivity water-deficit
