Fig. 5From: Culture-dependent and culture-independent characterization of bacterial community diversity in different types of sandy lands: the case of Minqin County, ChinaComparison of the distribution of control samples and rhizosphere samples at the phylum level. Proportional Venn diagram showing the number of OTUs found only in the soil (soil_only), only in the rhizosphere N. tangutorum (RN_only) (a) or H. ammodendron (RH_only) (b), and in both locations. These OTUs were used to create the abundance bar graphs and the relative abundance of raw reads for different phyla belonging to the OTUs depicted under the panel VennBack to article page
