Predicted virus–host linkages in Cr-contaminated soils. A A total of 1044 hits were obtained between 646 phage contigs and 279 bacterial genera, and these host genera were mainly from 8 bacterial phyla. From left to right and the first columns show the distribution of bacterial hosts at the phylum level; the second column depicts viral contigs linking to hosts in the seven soil samples; the third column shows the distribution of the bacterial host assigned with CRISPR approaches at the genus level. The height of the column section represents the abundance of viruses and hosts. The results revealed that these viral host species predicted in the soil polluted by high Cr concentration mostly belong to the bacterial genera which have been reported to have strong adaptivity to better survive in heavy metal-polluted habitats. B The relative abundance of polyvalent phages within the viral communities of Cr-contaminated soils. Polyvalence was found to be consistently higher in soil samples with higher available Cr concentrations
