Deciphering the Salt Tolerance Mechanisms of the Endophytic Plant Growth-Promoting Bacterium <i>Pantoea</i> sp. EEL5: Integration of Genomic, Transcriptomic, and Biochemical Analyses.

ABSTRACT: Soil salinization poses a significant threat to global agricultural productivity. Salt-tolerant plant growth-promoting bacteria (ST-PGPB) have shown great potential in enhancing crop resilience under saline stress, yet the molecular basis of their intrinsic tolerance remains incompletely understood. To address this, we employed an integrated genomic, transcriptomic, and biochemical approach to investigate the salt tolerance strategies of Pantoea sp. EEL5, an endophytic ST-PGPB isolated from Elytrigia elongata. The results demonstrated that EEL5 exhibited remarkable salt tolerance and efficiently removed Na⁺ via extracellular adsorption and intracellular accumulation. Genomic analysis identified key genes responsible for Na⁺ efflux, betaine synthesis and
