Sd. ludwigii possesses a nearly full meiotic gene complement. a Meiotic genes of Sd. ludwigii and other yeast representatives. Genes were classified into functional groups (top) based on the associated GO terms of their S. cerevisiae homologs (www.yeastgenome.org), and the total gene count for each of them is plotted for each species (right). Apart from the presumably asexual species C. glabrata [41], Hanseniaspora jakobsenii, for which sexual sporulation has not been reported to date [42], and the mitosporic yeasts Candida mycetangii, C. orba, C. stellimalicola, C. ponderosae, C. montana, and C. vartiovaarae, all other 71 species included in this analysis are sexual. The names of species with documented meiotic recombination appear in bold [43,44,45,46,47]. b Meiosis/meiotic recombination-related genes that are absent from the reference Sd. ludwigii strain are summarized here. Presence or absence of homologs is also indicated for all other species, for comparison. The function of each gene is indicated by a colored circle beneath its name (color code as in a)
