Additional file 2: Figure S2. of Pyrosequencing analysis revealed complex endogenetic microorganism community from natural DongChong XiaCao and its microhabitat

Operational taxonomic units (OTUs) rank curves of 16S rRNA gene (a) and ITS sequences (b) at a 97 % cut off value. In each figure, the x-axis represents the OTUs listed as the abundance in descending order and the y-axis represents the relative abundance of each OTU. The OTU rank curve could explain the diversity and the evenness of the organism community. The width of the curve reveals the diversity of the organism community along the x-axis; a wider curve indicates more diversity. Evenness of the organism community is suggested by the pattern of the curve. A flatter curve suggests a more even organism community. (TIF 216 kb)
