Bacterial composition of different Geodorum species. A, B and C: Venn diagram of different groups at the OTU level (A: in the roots of GE, GD_roadside, GD_understory and GA groups; B: in the rhizosphere soil of GE, GD_roadside, GD_understory and GA groups; C: in the root and rhizosphere soil groups in all the Geodorum species). D and E: Bar graphs of the bacterial community composition at the phylum level (D: in the roots of Geodorum; E: in the rhizosphere soil of Geodorum). F and G: Bar graphs of the bacterial community composition at the genus level (F: in the roots of Geodorum; G: in the rhizosphere soil of Geodorum)
