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.

Salt stress is one of the most important abiotic factors that negatively affects sustainable crop production, agricultural productivity, and microbial life. Increasing salt growth development barley, posing a threat to global food security. It now known inoculation plant growth-promoting rhizobacteria (PGPR) has significant potential in increasing tolerance yield products. This study focused on effects Bacillus cereus CUN6 thuringiensis SIRB2, isolated from coastal zone tested for their PGPR capacities, physiological (root length, shoot biomass, dry weight) biochemical (total chlorophyll, total protein, hydrogen peroxide, lipid peroxidation, peroxidase activity (POX), catalase (CAT)) analyses Hordeum vulgare L. seedlings under stress. The results showed two bacterial inoculations alleviated negative by root-shoot weight, chlorophyll content, protein content barley plants. However, B.thuringiensis increased especially root weight compared B.cereus. On other hand, B.cereus significantly stress; these increases were 17%, 5%, 7%, respectively. 4% 300 mM NaCl control. When terms antioxidant defense system, was more effective CAT activity, while POX activity. Under stress, decreased H2O2 barley; decreases 16% 10%, Additionally, TBARs determined as 8% 9%, respectively, These indicated both can alleviate regulating metabolism. research biofertilizers against based analysis.

The cultivation of tartary buckwheat serves dual roles, offering health benefits and nutritional advantages. Nonetheless, its is challenged by issues such as soil degradation climatic drought. Plant growth-promoting (PGP) microorganisms hold promise for addressing these challenges. In this study, we investigated the effects Serendipita indica inoculation on root-associated microbial communities buckwheat. Additionally, used S. to construct synthetic consortia, their role in promoting growth enhancing drought resistance was evaluated. This study found that colonization promoted enrichment beneficial Actinobacteriota, Sphingomonas , Mortierella while reducing relative abundance pathogenic genera including Cladosporium Alternaria Acremonium . addition, consortia significantly photosynthesis biomass accumulation buckwheat, also improving structure fertility. Under conditions, introducing groups markedly boosted root development, lowered density stomata rate transpiration leaves, decreased H 2 O Malondialdehyde (MDA) levels, thus greatly buckwheat’s conclusion, our findings demonstrated constructed with can promote enhance resistance. However, specific molecular mechanisms underlying require further investigation future studies. These will provide important theoretical support development novel fertilizers.

Among heavy metals, cadmium (Cd) is shown to have adverse consequences for plants. Due its harmful nature and ability move through the soil–plant system, it a very worrying element soil experts plant physiologists. In this work, we designed pot experiment study influence of three concentrations (0, 15, 30 mg/kg) explore physiological impacts, portioning in whole hulless barley varieties. Our findings demonstrated marked Cd accumulation roots, leaves, stems under severe stress (30 mg/kg). was also reduce photosynthetic activity, chlorophyll fluorescence (Fv/Fm), transpiration rates (E). The application increased activities catalase (CAT), ascorbate peroxidase (APX), guaiacol (POD) enzymes, as well levels oxidative markers such malondialdehyde (MDA), hydrogen peroxide (H2O2), proline. These results reflect negative effects on morpho-physiological traits genotypes. However, principal component analysis indicated significant correlation between indicators enzymatic activities, along with different tolerance Tombari, Assiya, Giza 130 When exposed Cd, these varieties shifted amount energy from growth produce antioxidant compounds osmolytes. Despite this, defenses did not effectively shield detrimental induced by at vegetative stages. Consequently, highly recommend testing Cd-contaminated investigate rate seeds, harvested part used human nutrition.
