日本裂殖酵母是由日本裂殖酵母变种组成。、日本血吸虫和日本血吸虫变种。具有独特的特征，如显著的菌丝生长，这在其他裂殖酵母中是没有的；然而，关于它的多样性和进化，特别是交配和产孢量的信息仍然有限。在这里，我们比较了17个日本血吸虫野生株的生长和交配表型，其中包括8个日本血吸虫变种。从一种昆虫(果蝇)中新分离的日本菌株。与现有的从水果/植物中分离的野生菌株不同，从果蝇中分离的菌株即使在氮素充足的条件下也能高频产孢。此外，其中一个果蝇品系被碘蒸汽染色，尽管模式品系为日本血吸虫变种。日本鱼没有被染上。序列分析进一步表明，8个果蝇品系的信息素相关基因的核苷酸和氨基酸序列存在差异，表明不同遗传背景的日本血吸虫细胞之间经常发生杂交。许多酵母生态尚不清楚，但我们的发现表明，果蝇等昆虫可能是交配和产孢子的良好生态位，并将为了解信号转导的产孢机制以及酵母的生态和进化提供基础。
The fission yeast Schizosaccharomyces japonicus, comprising S. japonicus var. japonicus and S. japonicus var. versatilis varieties, has unique characteristics such as striking hyphal growth not seen in other Schizosaccharomyces species; however, information on its diversity and evolution, in particular mating and sporulation, remains limited. Here we compared the growth and mating phenotypes of 17 wild strains of S. japonicus, including eight S. japonicus var. japonicus strains newly isolated from an insect (Drosophila). Unlike existing wild strains isolated from fruits/plants, the strains isolated from Drosophila sporulated at high frequency even under nitrogen-abundant conditions. In addition, one of the strains from Drosophila was stained by iodine vapor, although the type strain of S. japonicus var. japonicus is not stained. Sequence analysis further showed that the nucleotide and amino acid sequences of pheromone-related genes have diversified among the eight strains from Drosophila, suggesting crossing between S. japonicus cells of different genetic backgrounds occurs frequently in this insect. Much of yeast ecology remains unclear, but our findings suggest that insects such as Drosophila might be a good niche for mating and sporulation, and will provide a basis for the understanding of sporulation mechanisms via signal transduction, as well as the ecology and evolution of yeast.
