Bacterial endophytic diversity within roots and panicles of Setaria pumila and Setaria viridis (A) α-diversity metrics for communities within roots and panicles of Setaria spp. Significant (p < 0.001) higher richness was observed in root tissues when compared to panicle communities. Evenness (Simpson-index), was also significantly different between plant organs. (B) Principal coordinate analysis (PCoA) of S. pumila and S. viridis samples that were collected simultaneously from the same locations revealed the plant organ as the main driver of endophyte communities (separation across the first PC).
