Plant host explains variation in root endophytic bacterial community.

(A) CAP plot showing the live soil endophytic root microbiome of Carduus nutans (red), Conyza canadensis (blue), Heliopsis helianthoides (green), Monarda fistulosa (purple) and Ratibida pinnata (orange) [ADONIS p < 0.001, r2 = 0.11, n = 201]. (B) CAP plot showing the endophytic root microbiome clustered by soil history [ADONIS p < 0.001, r2 = 0.03, n = 201] (C) CAP plot showing both the live and autoclaved soil endophytic root microbiome clustered by plant host [ADONIS p< 0.001, r2 = 0.07, n = 247] (D) CAP plot showing both live and autoclaved soil endophytic root microbiome separated by soil history [ADONIS p< 0.001, r2 = 0.02, n = 247].
