Complete mitochondrial genome of spined sleeper Eleotris oxycephala (Perciformes, Eleotridae) and phylogenetic consideration

摘要

The complete mitochondrial genome of Eleotris oxycephala was determined to be 16,527 bp in length with (A + T) content of 53%, and it consists of 13 protein-coding genes, 22 tRNAs, 2 ribosomal RNAs, and a control region. The gene composition and the structural arrangement of the E. oxycephala complete mtDNA were identical to most of other vertebrates. Phylogenetic analysis based on different sequences of species of the Gobioidei suborder and different methods showed that E. oxycephala formed a cluster with Eleotris acanthopoma and Eleotridae were divided into two clades. Furthermore, extensive taxon sampling and more molecular information are needed to confirm the phylogenetic relationships among the Gobioidei. (C) 2015 Elsevier Ltd. All rights reserved.
