FIG 7.

Transcriptional activity of putative methylators in a permafrost thawing gradient. Counts of mapped metatranscriptomic reads to 111 putative methylators identified in a permafrost thawing gradient in bog and fen samples (31). (Center) Total reads mapping to the hgcA gene within a phylum per sample normalized by transcripts per million (TPM). Heat map color scale represents a continuous gradient between 0 and 100 TPM, and a break between 100 and 165 TPM to better visualize results in the low range. (Right) Total hgcA counts per sample in TPM. (Top) Average overall expression of genomes within a phylum across all bog and fen samples in TPM.
