Maize ranks among the most essential crops globally, yet its growth and yield are significantly hindered by salt stress, posing challenges to agricultural productivity. To utilize saline-alkali soils more effectively enrich maize germplasm resources, identifying salt-tolerant genes in is essential. In this study, we used a inbred line, SPL02, salt-sensitive Mo17. We treated both lines with 180 mmol/L sodium chloride (NaCl) for 0 days, 3 6 9 days at three-leaf stage (V3). Through comprehensive morphological, physiological, transcriptomic analyses, assessed stress effects identified hub pathways associated tolerance. Our analysis 25,383 expressed genes, substantial differences gene expression patterns across treatment stages. found 8,971 differentially (DEGs)-7,111 unique SPL02 4,791 Mo17-indicating dynamic changes under stress. DEGs primarily MAPK signaling pathway, phenylpropanoid biosynthesis, hormone conditions. Mo17, responses mediated through abscisic acid-activated pathway response. Additionally, our weighted co-expression network (WGCNA) pinpointed five that likely play central roles mediating These functions including phosphate import ATP-binding protein, glycosyltransferase, WRKY transcription factors. This study offers valuable insights into complex regulatory networks governing response identifies further investigation. findings contribute knowledge enhancing resilience sustainability saline-affected environments.

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.
