(a) Each branch of phylogenetic tree represents a species and the length of the branch is the evolutionary distance between the two species, that is the degree of difference in the species. (b) Relative abundance of the bacterial species in single (A) and interplant cultures (B). The vertical axis represents the species name at a certain classification level, and each bar corresponding to the species represents the average relative abundance of the species in each sample group, and the different colors indicate different group in the middle area is the difference between the abundance percentages of the two groups in the set confidence interval. The color of the dot is displayed as the group color with a large abundance of species and the type I interval on the dot is the upper and lower limits of the difference value. The rightmost side is the P value, *0.01 < P ≤ 0.05**0.001 < P ≤ 0.01***P ≤ 0.001.
