Exomer components and their relationship in Fungi. Phylogenetic tree showing the duplication of ChAP components during Saccharomycotina evolution from a pre-duplicated ChAP protein to the common ancestor of Bch1/Bud7 and common ancestor of Bch2/Chs6, followed by the duplication giving rise to these individual components prior to Saccharomyces speciation. Smaller internal boxes denote the four near Saccharomyces-specific proteins (Green box: Bud7 clade: Purple box: Bch1 clade; Orange box: Chs6 clade; Blue box: Bch2 clade), while the outer boxes denote the clades of BB8 (i.e. Yellow box: Bch1, Bud7 and preduplicated homologues) and BC8 (Pink box: Bch2, Chs6 and preduplicated homologues) respectively. The MrBayes topology is shown with posterior probability values (first number) and ML bootstrap support values (second number) overlain on all nodes reconstructed with 0.8PP (Bayesian posterior probabilities) and 50% or better. Scale bar: Number of changes or substitution per site.
