Fig. 1From: Conserved and lineage-specific hypothetical proteins may have played a central role in the rise and diversification of major archaeal groupsThe distribution of the 10,866 families across the 1179 representative genomes. A The distribution of 10,866 widely distributed protein families (columns) in 1179 representative genomes (rows) from Archaea. Data are clustered based on the presence (black) and absence (white) profiles (Jaccard distance, complete linkage). B Tree resulting from the hierarchical clustering of the genomes based on the distributions of protein families in ABack to article page
