Abstract:
The complete mitochondrial genome (mitogenome) of Cryptocentrus yatsui was first determined. The genome was 16,584 bp in length and consisted of 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes, and 2 main noncoding regions (the control region and the origin of the light strand replication), the gene composition and order of which were similar to most other vertebrates. The overall base composition values of the heavy strand are 26.0% for T, 29.9% for C, 26.4% for A, and 17.7% for G, with a slight A+T bias of 52.4%. To clarify the phylogenetic relationships of C. yatsui within the genus Cryptocentrus, 18 sequences, which were generated from COI region of six species, were used to construct the neighbor-joining phylogenetic tree. And we found that C. yatsui was rooted with the other Cryptocentrus species and has a distant relationship with others.
