Aromatic compound degradation genes and pathways in Arctic Ocean Chloroflexi MAGs. a Abundance of aromatic compound degradation genes in Chloroflexi MAGs from the Canada Basin (pie chart) and a breakdown of those found specifically in SAR202-VII-2 (column plot). b Predicted aromatic ring-opening enzymatic reactions identified in SAR202-VII-2 with gene loci displayed in the colored boxes. Genes in green and blue boxes were most closely related to homologs from terrestrial or marine bacteria, respectively. Genes in the blue/green boxes were in clades containing diverse environmental bacteria. c Examples of predicted aromatic ring-modifying enzymatic reactions identified in SAR202-VII-2
