Gut microbiota and health

The rhizospheric microbial community is affected by plant genera and genotypes. However, the rhizospheric effect on the microbial community from distinct plant species belonging to the same genus is poorly understood. This study hypothesized that the rhizospheric microbial community differs between plant species from the Phaseolus genus (i.e. P. acutifolius A. Gray, P. lunatus L., P. vulgaris L., P. microcarpus Mart., and P. filiformis Benth.) and that these differences could be related to phylogenetic differences found in these plant species. The redundancy analysis showed a distinct microbial community mainly when comparing P. lunatus and P. microcarpus. The microbial richness and diversity varied among plants, where P. lunatus showed the highest richness and diversity and P. microcarpus the lowest. The abundances of specific microbial phyla varied between the rhizosphere of Phaseolus species. Actinobacteria was abundant in the rhizosphere of P. acutifolius, P. vulgaris, and P. filiformis, while Acidobacteria was abundant in the rhizosphere of P. lunatus. This study revealed that each Phaseolus species recruits a distinct microbial community in the rhizosphere, with the rhizosphere community of the domesticated species P. lunatus being the most distinct.
