Project description:Cheilinus oxycephalus is a marine fish species, belonging to the family Labridae and naturally distributed in Indo-Pacific waters. We obtained the first complete mitochondrial genome of this species using next-generation sequencing technology. This genome is 17,698 bp, and contains 13 protein-coding genes, 2 rRNAs, 22 tRNAs, and a D-loop region. These genes are mostly encoded on the heavy strand except for ND6 and eight tRNA genes. The AT content is 52.32%. These characteristics are similar to other bony fish. This mitochondrial genome would be used as a resource for phylogenetic reconstruction.
Project description:Cheilinus trilobatus Lacépède, 1801 is a species of genus Cheilinus. In this study, we sequenced the complete mitochondrion genome of C. trilobatus. The mitochondrial genome was 17,292 bp, consisting of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one non-coding control region (D-loop). The nucleotide composition was 27.31% A, 25.1% T, 17.23% G, and 30.36% C. Phylogenetic analysis suggested that C. trilobatus was closely related to Cheilinus oxycephalus. The complete mitogenome of C. trilobatus provided basic data for the genetic diversity conservation of this species.
Project description:We report here the complete mitochondrial (mt) genomes of six individuals of Cheilinus undulatus (Napoleon Wrasse), an endangered marine fish species. The six mt DNA sequences had an average size of 17,000 kb and encoded 22 tRNA, two sRNA, 13 highly conserved protein coding genes and a control region. The polymorphic variation (control region) in these six individuals suggests their potential use as a specific marker for phylogeographic conservation. Moreover, the sequence polymorphism within the control region (D-loop) suggests that this locus can be applied for phylogenetic studies.
