Microbial community analysis of healthy and diseased rhizome soil. (A and B) Alpha-Shannon diversity indices of bacterial (A) and fungal (B) communities in the healthy and diseased P. cyrtonema rhizome soil. The healthy sample bacterial and fungal alpha indices were 4.9272 and 3.9818, respectively, and diseased sample bacterial and fungal alpha indices were 2.9047 and 1.8935, respectively, on average; n = 12, Student’s t test, P < 0.001. (C and D) PCA of bacterial (C) and fungal (D) community beta diversity of the healthy and diseased rhizome soil; bacteria: R = 0.9685, P = 0.003; fungi: R = 0.9241, P = 0.003. (E and F) Bacterial and fungal genera community structure of the healthy and diseased rhizome soil. (E) Bacterial community (top 10 genera in relative abundance). (F) Fungal genera community.
