| Outline of Final Research Achievements |
We see abundant species diversity in diverse environments on Earth. Even closely related species diverged distributed in different climatic zones. What are the genetic mechanisms behind such species diversification? We tested this question using the subgenus Idaeobatus, a genus of raspberries, which has speciated into a variety of climatic zones in Asia. We found that the genus Idaeobatus has repeatedly speciated from cold to warm climatic zones, and that speciation from temperate to subtropical climates has occurred in different phylogenetic groups. Furthermore, genome re-sequencing data suggest that introgression among species might be involved in species diversification.
