Schizosaccharomyces japonicus: A Distinct Dimorphic Yeast among the Fission Yeasts
Abstract
Genomic sequencing data and morphological properties demonstrate evolutionary relationships among groups of the fission yeast, Schizosaccharomyces Phylogenetically, S. japonicus is the furthest removed from other species of fission yeast. The basic characteristics of cell proliferation are shared among all fission yeast, including the process of binary fission during vegetative growth, conjugation and karyogamy with horsetail movement, mating-type switching, and sporulation. However, S. japonicus also exhibits characteristics that are unique to filamentous fungi. S. japonicus is a nonpathogenic yeast that exhibits dimorphism. Depending on the environmental conditions, S. japonicus transforms from yeast cells into filamentous cells (hyphae), and blue light triggers synchronous septation of hyphal cells. A rough version of the whole-genome sequence is now available, facilitating genetic manipulation of S. japonicus. Furthermore, the extensive genetic knowledge available for S. pombe is aiding the development of genetic tools for analyzing S. japonicus. S. japonicus will help shed light on the evolutionary relationships among the fission yeast.
