Additional file 3: of Metagenome-assembled genomes uncover a global brackish microbiome

Depicting COGs used as phylum-specific, or class-specific for proteobacteria, single-copy genes (SCGs). A COG is considered a SCG for a clade if it is present in >97 % of the respective reference genomes with an average copy number <1.03. A COG marked with a 1 is considered an SCG for the clade corresponding to that column. Only clades with at least three genera represented by reference genomes are included in the table. (XLS 320 kb)
