Improved breeding of fugu following whole genome Sequencing

作为第一个具有商业价值的鱼类，我们对河豚进行了基因组测序。我们试图利用这些基因组信息来改进该物种的育种。我们利用物种间杂交，找到了负责每种表型（如体型、规模发育、对特定寄生虫的抗性和行为模式）的特定位点。此外，我们发现了性别决定基因，并建立了该物种的性别控制系统，其中雄性更有价值。

As the first commercially valuable fish species, tora-fugu(Takifugu rubripes) genome was sequenced. We tried to utilize this geneme information for improved breeding of this species . We fond specific loci responsible for each phenotypes，such as body size, scale development, resistance against a specific parasite, and behavioral patterns, using inter-species hybridization among Takifugu species. In addition, we found sex determination gene, and developed sex control system of this species, in which male is more valuable.
