Glass phylogeny. To identify Glass homologues, we searched for Glass-like sequences with BLAST and obtained a cluster map by using all-against-all pairwise similarity. In this graph, those sequences that are most similar appear clustered together, and connected by a darker line (a). Based on these data, we built a maximum likelihood tree for Glass (b) (for further details, see the “Methods” section, the tree file and the sequences that we used for it are included in the Additional file 3)
