基因组测序数据和形态学特性证明了裂殖酵母（裂殖酵母）群体之间的进化关系。从系统发育上看，日本血吸虫与其他裂殖酵母物种的距离最远。细胞增殖的基本特征是所有裂殖酵母共有的，包括营养生长过程中的二元裂变、接合和带有马尾运动的核配、交配型转换和孢子形成。然而，日本血吸虫也表现出丝状真菌所独有的特征。 S. japonicus 是一种表现出二态性的非致病性酵母。根据环境条件，刺参从酵母细胞转变为丝状细胞（菌丝），蓝光触发菌丝细胞同步分隔。现在可以获得全基因组序列的粗略版本，有利于日本血吸虫的遗传操作。此外，丰富的粟酒裂殖酵母遗传知识有助于开发用于分析日本刺参的遗传工具。日本链霉菌将有助于阐明裂殖酵母之间的进化关系。
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.
