dc.description.abstract | Despite wide interest in the group of batoids, there is no molecular phylogenetic analysis of Rajidae inhabiting the Korean waters. A comprehensive genus-level sampling ( > 60% species-level) was made from the genera Okamejei, Dipturus, Hongeo, Raja, Bathyraja for the analysis of intergeneric relationships. Using 13 Protein coding genes (PCG) of mitochondrial genome and 2 nuclear genes (RAG1, SCFD2) from 40 species including other family of batoids and one shark as an outgroup, are resolved most relationships with high confidence of Rajidae family inhabiting the Korean waters. The resulted phylogeny is compared with the previous morphological and genetic studies showing relationships among Rajidae. Moreover the full time-calibrated tree of Rajidae evolution is investigated using 9 fossil information as well as molecular data. Rajidae represent an older group that originated ~ 69.5 Ma (K/T boundary), with most diversification occurring since the early miocene (~ 23.5 Ma) related with the radiation of other marine biota. In addition, a hypothesis of the negative correlation between depths and divergence times of skates in the Korean waters is suggested.geo, Raja, Bathyraja for the analysis of intergeneric relationships.
