Fig. 6

Phylogenetic dendrogram of specific bacteria (in the left) between straw group (S) with earthworms groups (W) samples and their LDA score (in the right). In the figure at right, different colors represented different groups, the horizontal axis is LDA score after LDA analysis and the longitudinal is the significant microbial group. In the left, different colors represent different groups, and different color nodes in the tree represent the bacterial groups that play an important role in the corresponding grouping of colors. Yellow nodes represent bacteria that have no significant differences from each other. The name of the species represented by the letters in the graphic displayed in the right legend. Bacterial taxa significantly enriched in samples from earthworm to straw group and then the control. Taxa differentiating were detected by the LefSe analytic method (p < 0.05, log linear discriminant analysis [LDA] score > 2)
