Biological functions of novel orthogroups based on Saccharomyces cerevisiae genes. Each colored box, coded by the phylogenetic group, is a summary of the extant biological processes that are associated with past evolutionary transitions. The number at each node represents the total number of novel orthogroups for that clade. Numbers in parentheses indicate the number of species studied in each phylum. The phylogenetic hypothesis of fungal phyla interrelationships is as per references in the text.
