Genomic analyses were performed using selectedeconomic importance, but its productivity is often affected by salt stress in arid and semi-arid regions. Endophytic bacteria, which colonize the internal tissues of plants in a symbiotic manner, represent a promising solution for improving the salt tolerance of alfalfa. To improve alfalfa salt stress resistance, four endophytic bacteria (M17, M50, S113 and strains M17 that show a good protection from salt stress. M17 is identified as Pseudomonas aeruginosastrain, Comparative genomic for both strains is illustrated. For Pseudomonas strains (M17): two strains associated with plants and two non-associated with plant, one phytopathogens and Human pathogen). The results shows 521 common genes and synteny analyses revelas a high conservation between the bacteria associated with plants.
