Evolution of the Noncoding Features of Sea Snake Mitochondrial Genomes within Elapidae.

ABSTRACT: Mitochondrial genomes of four elapid snakes (three marine species [Emydocephalus ijimae, Hydrophis ornatus, and Hydrophis melanocephalus], and one terrestrial species [Sinomicrurus japonicus]) were completely sequenced by a combination of Sanger sequencing, next-generation sequencing and Nanopore sequencing. Nanopore sequencing was especially effective in accurately reading through long tandem repeats in these genomes. This led us to show that major noncoding regions in the mitochondrial genomes of those three sea snakes contain considerably long tandem duplications, unlike the mitochondrial genomes previously reported for same and other sea snake species. We also found a transposition of the light-strand replication origin within a tRNA gene cluster for the thr
