Maximum likelihood phylogeny (RAXML, model LG+Γ) of the HGM superfamily and the α1 domain core amino acid sequence integrated in a slightly modified dataset [22] now incorporating mating type genes found in V. longisporum strain VL1 and VL2, and V. albo-atrum. Bootstrap support values above 70 are shown. Labeling is as follows: α1 (green), MATA_HMG (yellow), SOX (orange), HMGB (blue), Phycomyces blakesleeanus (Zygomycota), sexM and sexP are circled in purple and Verticillium species (white). The number after the abbreviation indicates the domain as: 1, α1; 2, MATA_HMG; 3, SOX; 4, HMGB; 5, HMG; 6, SeqP and 7, SeqM. In the case more than one domain is present in a species, the suffix a, b, c is added. Accession numbers for proteins used for the phylogeny is listed in Additional file 14.
