The ancestral duplications, subsequent transfers, and gene losses in the NR-PKS complement—annotated on the simplified species tree of higher fungi. The events were annotated based on the results of ALE reconciliation. Deletions are indicated by violet bubbles, duplications by red bubbles. Transfer events are marked through their respective numbers from table 1 (filled outlines indicate donors, hollow outlines indicate transfer acceptors). Salient broad taxa within higher fungi are highlighted by colored backgrounds (in clockwise direction: Basidiomycota, Leotiomycetes, Sordariomycetes, Dothideomycetes, Eurotiomycetes). Subscript on branches denotes predicted numbers of, respectively, duplications/deletions/genes for respective branch. For ease of reference, some nodes were collapsed (thickened branches, proportional to the number of species/strains). Duplications within the Agaricomycetes clade are not shown due to space constraints (see fig. 4).
