Figure 5.
Functional roles of a set of genes specific to S. bayanus. (A) A group of genes is strongly induced by oxidative stresses but not other stresses. We predicted biological process annotations for this cluster of genes and show the S. cerevisiae orthologs and their experimentally based biological process annotations as assigned by the Saccharomyces Genome database. The predicted annotations are the two highest scoring annotations; Table S4 contains a complete list, for all genes and Figure S7 describes the quality of gene function predictions across all terms. (B) The GAL80 ohnolog 670.20 regulates a set of genes unique to S. bayanus when cells are shifted from raffinose to galactose. Graphs show log2 ratios of expression data from microarrays, zero transformed to the initial timepoint in wild type cells.
