Fig. 2 Principal coordinate analysis (PCoA) of phyllosphere bacterial community structure in desert shrubs based on Bray-Curtis distance. (a) Effect of leaf ecological niche on phyllosphere bacterial community structure; Effect of plant species identity on endophytic (b) and epiphytic (c) bacterial community structure; Effect of plant genus identity on endophytic (d) and epiphytic (e) bacterial community structure. The dashed ellipses in the figure represent the distribution range of within-group data based on a 95% confidence interval.
