FIG 1 .

Molecular phylogeny, mating system, and ecology of Malassezia and other basidiomycete representatives. The tree is based on the nucleotide alignment of the D1/D2 domain of the LSU (large subunit) rRNA gene sequences and was inferred by maximum likelihood using the GTR (general time reversible) model and a 1,000-replicate bootstrap analysis (values of >50% are shown). Sporidiobolus salmonicolor and Microbotryum silenes-dioicae were used as an outgroup. GenBank accession numbers are shown in parentheses after species names. PUC., AGA., and UST. are abbreviations for Pucciniomycotina, Agaricomycotina, and Ustilaginomycotina, three major lineages in Basidiomycota. In the mating systems panel, numbers inside each box indicate the estimated number of alleles. All remaining features are as given in the key.
