The complete mitochondrial genome of Cheilinus undulates based on high-throughput sequencing technique

Abstract

Cheilinus undulatus is a Critically Endangered ocean fish, which is also a higher level predator in coral reef. The complete mitochondrial genome of Cheilinus undulatus has been sequenced by high-throughput sequencing technology. According to the results, the mitochondrial genome of Cheilinus undulatus is 17,184 bp long and consists of 38 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. The nucleotides compositions of the light strand are 27.62% of A, 24.82% of T, 16.66% of G and 30.90% of C. With the exception of ND6 and 8 tRNA genes, all other mitochondrial genes are encoded on the heavy strand. C. undulates mitochondrial genome contains a 568 bp sequences that is a non-coding DNA domain. No homology sequence had been found through BLAST in GenBank. The sequences are probably characteristic species marker of C. undulates.
