Figure 5. Changes in fungal communities in notoginseng cropping and traditional cropping soils.

(a) PCoA ordination plots show the relatedness of samples that were separated using Unweighted UniFrac distances of classified 18S rRNA gene sequences. (b) Heat map shows major fungal orders with average relative abundance >0.5% in all samples. Clustering on the x-axis is based on fungal composition of the samples. Data are mean values of n = 3; asterisks denote significant differences between the traditional cropping and notoginseng cultivation in the relative abundance of soil fungal taxa at P < 0.05.
