Tissue-specific diversity of bacterial endophytes in Mexican husk tomato plants (Physalis ixocarpa Brot. ex Horm.), and screening for their multiple plant growth-promoting activities.

ABSTRACT: The endophytic bacterial diversity of root, stem, and leaf tissues of Mexican husk tomato plants (Physalis ixocarpa) was compared and deciphered, and screened for their plant growth-promoting activity and antagonism against fungal phytopathogens. Total 315 isolates (108 roots, 102 stems, and 105 leaves) were obtained and characterized by 16S ribosomal gene sequencing. The most abundant genera were Bacillus, Microbacterium, Pseudomonas, and Stenotrophomonas. Unique species were found for each tissue analyzed, along with B. thuringiensis, B. toyonensis, Neobacillus drentensis, Paenibacillus castaneae, P. fluorescens, P. poae, and S. maltophilia present throughout the plant. Biodiversity indices did not show significant differences, but root tissues showed t
