Beta diversity was assessed by the Bray–Curtis test. In (A), the red dots indicate the control group, the blue dots indicate the RCC group, and the yellow dots indicate the SCC group. In (B), the green dots indicate the RCR group, and the purple dots indicate the SCR group. The beta diversity represents the degree of difference in diversity between two samples. The Bray–Curtis distance was computed via the 16S rRNA gene amplicon sequence data. (P values: P < 0.01 for the control group and RCC group; P < 0.05 for the control group and SCR group; and P < 0.01 for the RCC group and RCR group. P = 0.095 for the RCR group and SCR group)
