Fig. 3

Heatmap of abundance of endophytic fungi (top) and bacteria (bottom) of C. equisetifolia seeds, branchlets, roots, and litter at genus taxonomic levels. The abscissa is the sample name, and the ordinate is the species name. The clustering tree above the Heatmap represents the differences between samples, and the clustering tree on the left of the Heatmap represents the differences between microbes, with clustering into one group meaning that the differences are small. The variation of the abundance of different species in the sample is displayed through the color gradient of the color block. The value represented by the color gradient is on the right of the figure
