Fig. 4.

Beta diversity analysis of endophytic fungi and bacteria in tea leaves affected by blister blight disease at different stages (early, middle, and late) of disease progression as well as healthy ones. In the figure, the panel on the left is a hierarchical clustering tree, where samples are grouped according to their similarity. The shorter the branch length between samples, the more similar the two samples are. The panel on the right (drawn by default) is a stacked bar chart of the top 10 genera in abundance.
