Abstract Traditional Mesoamerican milpa is an ancient agroecosystem with actual cultural and economic importance, particularly for auto-consume agriculture. This includes several plants of American origin, establishing many beneficial ecological relationships among them plant-microbe interactions. In this study, a collection Streptomycesstrains was isolated from the rhizosphere native Cacahuacintle maize, squash, fava bean, huauzontle, all which exhibited various in vitro plant growth-promoting (PGP) activities such as ammonium production, phosphate solubilization, siderophore moreover, Streptomyces sp. FR-108 bean Streptomyces griseus MR-45 maize increased biomass short-term greenhouse assay. Among other strains, SR-10 squash albidoflavus MR-37 expressed extracellular enzyme secretion antagonistic against phytopathogenic fungi. Comparative fuctional genomic analysis these strains revealed extensive gene repertoires involved growth promotion by nutrient acquisition, tolerance to osmotic, drought, chemical, temperature stresses, mutualistic interactions, fungi, bacteria, insects, protist biocontrol. It not common find species genus Streptomycesas bacteria (PGPB) agroecosystems; however, findings highlight untapped potential milpa-associated members bioinoculants sustainable or agriculture underscore importance traditional agroecosystems sources microorganisms.
