| Outline of Final Research Achievements |
In this project we performed population genomics analyses of corals in Nansei Islands, southern-western Japan, where coral reefs around the area are regarded as a marine biodiversity hotspot. Firstly we investigated population structure of a coral Acropora digitifera whose genome was decoded. Taking advantage of the decoded genome and using genome-wide SNP analyses, we clarified the detailed population structure around Okinawa. In addition, using the coral genome data and big DNA sequencing data produced by next-generation sequencing technology, we developed molecular markers that could be used for studying population genetics of wide range of Acropora coral species. We investigated population structure of natural coral reefs and genetic diversity of farmed corals using the markers. These methods were also applied for development of molecular markers and studying population genetics of other marine organisms.
