Fungal 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 roots of Geodorum; G: in rhizosphere soil of Geodorum). GA, Geoderma attenuatum; GD, Geodorum densiflorum; GE, Geodorum eulophioides; OTU, operational taxonomic unit. In the Venn diagram, the circle for each group represents a taxon, and the area of the circle represents the relative abundance of that taxon in the corresponding group. Overlapping regions represent common taxa between different groups, while non-overlapping regions represent unique taxa
