Bacterial communities in the rhizosphere and endophytic compartments of A. mongholicus plants grown in Field I and Field II. A Taxonomic classification of bacterial OTUs grouped at the phylum level. The two bars represent the relative abundance of bacterial phyla in the rhizosphere of A. mongholicus grown in Field I and Field II. Unclassified represents those species not taxonomically annotated. B The linear discriminant analysis effect size (LEfSe) algorithm screened out the specific bacteria at the order level present in the rhizosphere of A. mongholicus grown in Field I (blue) and Field II (orange). C The ratio in relative abundance of the top ten endophytic bacteria at the phylum level in A. mongholicus roots grown in Field I and Field II. D Heatmap analysis of the relative abundance of the top 10 endophytic bacteria at the phylum level in A. mongholicus roots and stems grown in Field I and Field II. E The percentage converted from the proportion of relative abundance of the top 10 endophytic bacteria at the phylum level in A. mongholicus stems grown in Field I and Field II
