The budding yeast Saccharomycodes ludwigii. a Classification of Sd. ludwigii in the yeast phylogeny. WGD: whole-genome duplication; CUG-Ser1/2 and CUG-Ala: clades deviating from the universal genetic code. b Transmission electron microscopy images of representative Sd. ludwigii vegetative cells (reference strain NBRC 1722). c Life cycle of Sd. ludwigii. Brightfield images of strains NBRC 1722 and its diploid progenitor NBRC 1721 are shown. d Chiasmata in meiotic prophase I contribute to spindle stabilization and faithful segregation of homologous chromosomes. Meiosis in Sd. ludwigii, however, has been suggested to be achiasmate [11, 12]
