Properties of Astragalus sp. microsymbionts and their putative role in plant growth promotion.

ABSTRACT: The plant growth-promoting rhizobacteria have developed many different (indirect and direct) mechanisms that have a positive effect on plant growth and development. Strains isolated from Astragalus cicer and Astragalus glycyphyllos root nodules were investigated for their plant growth-promoting properties such as production of indole-3-acetic acid (IAA) and siderophores, phosphate solubilization, ACC deaminase activity, and tolerance to heavy metals. IAA production and P-solubilization were frequent features in the analysed strains, while siderophores were not produced by any of them. In this work, we investigated the presence of the acdS genes and ACC deaminase activities in Astragalaus cicer and A. glycyphyllos microsymbionts, classified within the genus Mesorhizobium. The results demons
