FAM155/Mid1 homologues are found in Metazoa, Fungi, and Cryptista. (A) Cluster map of identified FAM155/Mid1 protein sequences from eukaryotes. Edges correspond to BLAST comparison E-values colored according to the legend. (B) Maximum likelihood tree of HMM-identified FAM155/Mid1 homologues in eukaryotes. (C) Maximum likelihood tree of HMM-identified FAM155/Mid1 homologues in an expanded set of fungal proteomes. Leaves on the tree are colored according to major taxonomic groupings within fungi. For both trees, node support values for three separate analyses, SH-aLRT, LBP, and aBayes, are depicted by circular symbols with colors reflecting ranges of values as indicated in the node support legend. SH-aLRT, Shimodaira–Hasegawa approximate likelihood ratio tests; aBayes, approximate Bayes tests; LBP, local bootstrap probability tests; E-values, expect-values.
