a Several types of C-fixation AMGs carried by the virus. The comparison of C fixation types in polluted and non-polluted habitats is shown through pathways. Six types of C fixation pathways were involved in contaminated soils. b Aggregated boosted tree (ABT) models was used to evaluate the relative influence of selected factors on SOC. EC electronic conductivity, TN total nitrogen, WaterC water content, C fixation virus, relative abundance of virus carrying C-fixation AMGs in the metagenome. c Phylogenetic tree of AMGs. Different lineages of AMGs from bacteria are assigned different range colors according to their taxonomic relationships, as shown in the legend. The red stars and yellow dots represent sequences obtained from mining viruses and MAGs in this study, respectively. The gray lines indicate the predicted horizontal gene transfer events that occurred, and the red lines indicate the exact horizontal gene transfer that occurred between the viral AMGs and MAGs in situ.
