Outline of Final Research Achievements |
To present a genetic model of sex chromosome turnover, we have researched focusing on the Japanese wrinkled frog, which has XY and ZW chromosomes in the same species. Although the genome of the Japanese wrinkled frog was not deciphered, the genome sequencing, assembling and annotation of the Japanese wrinkled frog were carried out based on the results of this research.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、性染色体のターンオーバーという生命現象の謎を明らかにするために、同一種内にXYとZW染色体をもつ稀有な生物種であるツチガエルに着目して研究を行っている。本研究成果により、ツチガエルのゲノムがCG頻度が高いという独自の特徴を持つことが明らかになった。そのゲノムの独自性がツチガエル 独自の性染色体進化に関与している可能性が示唆された。
