| Abstract: | Background The genome sequence of the pufferfish Takifugu rubripes is an enormously useful tool in the molecular physiology of fish. Euryhaline fish that can survive both in freshwater (FW)
and seawater (SW) are also very useful for studying fish physiology, especially osmoregulation. Recently we learned that there
is a pufferfish, Takifugu obscurus, common name "mefugu" that migrates into FW to spawn. If T. obscurus is indeed a euryhaline fish and shares a high sequence homology with T. rubripes, it will become a superior animal model for studying the mechanism of osmoregulation. We have therefore determined its euryhalinity
and phylogenetic relationship to the members of the Takifugu family. |
