FIG 4.

Gene neighborhoods of diverse permafrost methylators containing similar hgcAB regions. Contigs containing similar hgcAB regions from putative methylators identified in a permafrost thawing system (31) were compared. Pairwise nucleotide BLAST between the genes for each contig was performed and visualized in Easyfig (106). Colors correspond to predicted functions of each gene. hgcAB genes were identified based on curated HMMs and reference sequences, while all other gene assignments were made based on Prokka predictions.
