Effects of Pb-Zn tailings on the taxonomic and functional profiling of microbial communities identified via high-throughput 16S rRNA gene sequencing from karst soil in Sidi Village. (A) Relative abundances of bacterial, archaeal and unassigned communities; (B) relative frequencies of dominant phyla (16S rRNA gene datasets); (C) P-values of the relationship between SOC levels and relative taxa frequencies at different taxonomic levels; (D) RDA plot used to show the relationship between SOC, DOC, POC, MBC and the 33 most abundant OTUs; and (E) heat map illustrating the relative frequencies of the 33 most abundant OTUs based on the V3–V5 region of the 16S rRNA gene sequences. The dominant phyla are indicated as follows: C, Euryarchaeota; C1, MCG; C2, MEG; C3, Thaumarchaeota; C4, DHVEG-6; C5, Acidobacteria; C6, Actinobacteria; C7, Aerophobetes; C8, Aminicenantes; C9, Armatimonadetes; C10, Bacteroidetes; C11, Candidate division OP3; C12, Chlamydiae; C13, Chlorobi; C14, Chloroflexi; C15, Cyanobacteria; C16, Deinococcus-Thermus; C17, Elusimicrobia; C18, Fibrobacteres; C19, Firmicutes; C20, GOUTA4; C21, Gemmatimonadetes; C22, Hydrogenedentes; C23, Latescibacteria; C24, Microgenomates; C25, Nitrospirae; C26, Omnitrophica; C27, Parcubacteria; C28, Planctomycetes; C29, Proteobacteria; C30, SHA-109; C31, SM2F11; C32, Saccharibacteria; C33, Spirochaetae; C34, TA06; C35, TM6; C36, Tenericutes; C37, Thermotogae; C38, Verrucomicrobia; C39, WCHB1-60; C40, WD272; C41, other; and C42, unassigned.
