Fig. 2

The community composition of dominant bacterial phyla within each group. Horizontal axis is the plant; vertical axis is the relative abundance of the corresponding plant. The community composition of dominant bacterial phyla within G1 (a and b). The community composition of dominant bacterial phyla within G2 (c and d). The community composition of dominant bacterial phyla within G3 (e and f). T-test was used to compare the bacterial community composition of the different plants within each group. “*”, “**”, “***” and “****”indicate significant differences at 0.05, 0.01, 0.001 and 0.0001, respectively
