Fig. 5From: Structure and function of the Arctic and Antarctic marine microbiota as revealed by metagenomicsComparison between the PM-RGC specific and OM-RGC specific ortholog functions based on the COG functions. Relative abundance of a given COG is the number of orthologs classified into this COG divided by the total number of orthologs. The 40 most abundant COGs significantly (p value < 0.01) enriched in PM-RGC are shownBack to article page
