TL;DR: This work uses positional cloning to identify the sex-determining locus of a medaka-related fish, Oryzias dancena, and finds that the locus on the Y chromosome contains a cis-regulatory element that upregulates neighbouring Sox3 expression in developing gonad.
Journal ArticleDOI
Geographic Variation and Diversity of the Cytochrome b Gene in Japanese Wild Populations of Medaka, Oryzias latipes
TL;DR: The phylogenetic relationships and the estimated divergence times suggest that three Japanese clades originated from a common ancestor and were separated during the Pliocene, and that the regional differentiation of subclades was closely connected with the geological history of the Quaternary.
Journal ArticleDOI
Molecular phylogeny of the medaka fishes genus Oryzias (Beloniformes: Adrianichthyidae) based on nuclear and mitochondrial DNA sequences.
TL;DR: Based on the combined data phylogeny, the Oryzias species were divided into three major species groups, namely the latipes, javanicus, and celebensis groups, which corresponded to the three chromosomal groups previously proposed from karyological analyses.
Journal ArticleDOI
Evidence for Different Origins of Sex Chromosomes in Closely Related Oryzias Fishes: Substitution of the Master Sex-Determining Gene
TL;DR: Oryzias species should provide a useful model for evolution of the master sex-determining gene and differentiation of sex chromosomes from autosomes and may have arisen and substituted for DMY in the lineage leading to O. luzonensis after separation from O. curvinotus ∼5 MYA.
Journal ArticleDOI

TL;DR: It is shown that deficiency in docosahexaenoic acid (DHA), an essential ω-3 fatty acid, can constrain freshwater colonization by marine fishes.
