Figure 2

Unrooted phylogenetic trees highlighting events of gene duplication and diversification in fungi. A) The endosomal Qa-SNAREs (Qa.III.b-type) of fungi split into two major branches, Pep12 and Vam3, within the Saccharomycotina. The syntaxin involved in trafficking towards the TGN, Tlg2 (Qa.III.a-type) is shown as outgroup. B) The phylogenetic tree of secretory syntaxins (Qa.IV-type) reveals independent expansions in Pezizomycotina and in the Saccharomyces senso-stricto clade. The latter expansion probably occurred during a whole-genome duplication, during which the other secretory SNAREs were duplicated as well. Note that independent duplications of Sso genes occurred in other lineages as well. In each tree, the diverged SNARE types are shown by different colors. In addition, the major phylogenetic groups of fungi are indicated. The labels on the major branches represent the Likelihood Mapping (left) and AU support values (right).
