Abstract Background Weeds represent a great constraint for agricultural production due to their remarkable adaptability and ability compete with crops. Climate change exacerbates the abiotic stresses that plants encounter. Therefore, studying plant responses adverse conditions is extremely important. Here, response saline stress at different temperatures of three weed species ( Chenopodium album , Echinochloa crus-galli Portulaca oleracea ) crops (maize, soybean rice) was investigated. Results The germination percentage notably decreased as salinity low increased. In contrast, maize rice consistently maintained high percentage, particularly when subjected levels. Regarding species, C. not significantly affected by salinity, but it in E. P. increasing salinity. mean time all increased especially lower temperatures. This effect most pronounced . exhibited significant reduction stem growth temperatures, while less reduced under similar conditions. Conclusion study showed successful did ensure early development emphasizes species-specific nature temperature-salinity interaction, perhaps influenced intraspecific variability. Increasing levels negatively impacted seedling yet higher partially alleviated these effects.

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.
