Fig. 5From: High-throughput sequencing technology reveals that continuous cropping of American ginseng results in changes in the microbial community in arable soilChanges in the composition of the bacterial community in soils used for traditional crops and American ginseng. a PCoA ordination plots show the relatedness of samples that were separated using weighted UniFrac distances of classified 16S rRNA gene sequences. b The relative abundances of the bacterial community (>1%) at the phylum level. TF and AGF refer to soil samples from traditional farmland and American ginseng farmland, respectively. An asterisk denotes a significant difference between TF and AGF at P < 0.05. The value of each bar represents the mean ± SD of n = 3Back to article page
