Fig. 3From: Diversity and composition of the Panax ginseng rhizosphere microbiome in various cultivation modesand agesEstimation of similarity and distance based on the hierarchical clustering tree of the samples (a, bacteria; c, fungi) and principal coordinate analysis (PCoA) (b, bacteria; d fungus) of the OTUs. The length of the branches in the hierarchical tree represents the distance between samples. The closer the two samples are on the PCoA plot, the more similar the species composition of the two samplesBack to article page
