Outline of Final Research Achievements

We conducted transcriptome analysis to clarify interspecific variation in the sequence of anuran functional genes, with results showing amino acid substitutions between species. Some lineages were suggested to be more genetically diverse than others, providing implications for the mechanisms of genotypic and phenotypic diversification. We also conducted de novo assembly of whole genome sequences to investigate the molecular basis of adaptive evolution, and a high-quality genome assembly was reconstructed.

Academic Significance and Societal Importance of the Research Achievements

近年では非モデル生物を対象にしたゲノミクス研究が比較的安価かつ簡便に行えるようになり、表現型の進化や多様化のメカニズムの理解が進んでいるが、両生類における研究の対象は一部の系統に限られていた。本研究の成果は、機能遺伝子の配列の多様性や表現型の多様化のメカニズムに関する新知見を提供することで、両生類の多様性の理解に貢献することが期待される。
