Figure 2: Yeast traits are widely distributed across the phylogeny.

The phylogeny of 1,154 yeasts and fungal outgroups built from 1,403 orthologous groups of genes. Branches are colored according to their taxonomic assignment to an order of Saccharomycotina (41). The innermost rings are colored by the top-level type of isolation environment in which each specific strain was isolated. The purple, yellow, and blue ring identifies the carbon growth classification for each strain. This classification is based on the carbon niche breadth, which is represented by the bar graph on the exterior of the tree, along with nitrogen breadth. All traits illustrated (isolation environment, carbon growth class, nitrogen breadth, and carbon niche breadth) are widely distributed across the tree; no order has one trait exclusively.
