Abstract By providing adaptive advantages to plants, desert microorganisms are emerging as promising solutions mitigate the negative and abrupt effects of climate change in agriculture. Among these, pseudomonads, commonly found soil association with plants' root system, have been shown enhance plant tolerance salinity drought, primarily affecting system architecture various hosts. However, a comprehensive understanding how these bacteria affect responses at cellular, physiological molecular levels is still lacking. In this study, we investigated two Pseudomonas spp. strains, E102 E141, which were previously isolated from date palm roots demonstrated efficacy promoting drought their These strains colonize roots, influencing by inhibiting primary growth while hair elongation lateral formation. Strains E141 increased auxin Arabidopsis , whereas effect was diminished IAA‐defective mutant exhibited reduced IAA production. all cases, effectiveness relies on functioning response transport machinery. Notably, such morphological changes provide an advantage plant, specifically under stress conditions salinity. Collectively, study demonstrates that leveraging host's signalling machinery, significantly improve resilience abiotic stresses, positioning them potential biopromoters/bioprotectors for crop production ecosystem restoration alignment Nature‐based Solution approaches.
