This paper informs the characterization by 16SrDNA partial sequence analysis of an endophytic diazotrophic bacterium isolated from roots of the halophyte shrub Prosopis strombulifera. The bacterium produced ABA, IAA, GA1, GA3 and jasmonic acid in chemically defined culture medium as assessed by GC-EIMS. The results emphasize the role of phytohormones produced by endophytic bacteria in the association host-beneficial microorganisms, especially under conditions of adverse environments.
