Primers for fourteen protein-coding genes and the deep phylogeny of the true yeasts.

ABSTRACT: The Saccharomycetales or 'true yeasts' consist of more than 800 described species, including many of scientific, medical and commercial importance. Considerable progress has been made in determining the phylogenetic relationships of these species, largely based on rDNA sequences, but many nodes for early-diverging lineages cannot be resolved with rDNA alone. rDNA is also not ideal for delineating recently diverged species. From published full-genome sequence data, we have identified 14 regions of protein-coding genes that can be PCR-amplified in a large proportion of a diverse collection of 25 yeast species using degenerate primers. Phylogenetic analysis of the sequences thus obtained reveals a well-resolved phylogeny of the Saccharomycetales with many branches having high bootstrap suppor
