Project description:In the present study, for the first time, we reported the complete mitochondrial genome of Lethrinops lethrinus, which is 16,582?bp in length, including 13 protein-coding genes, 2 ribosomal RNA, 22 transfer RNA genes and a control zone. Moreover, its GC content is 45.99% (27.42% A, 26.59% T, 30.10% C, and 15.88% G), similar to that of Alticorpus geoffreyi (GC content of 45.82%). We further made the phylogenetic tree on the complete mitochondrial genomes of the above two species and other 12 closely related species to show their phylogenic relationship. The above results would facilitate our understanding of the evolution of Cichlidae mitochondrial genome.
Project description:The grass emperor Lethrinus laticaudis is a coral reef fish that has high value to fisheries and is vulnerable to overharvesting. The complete mitochondrial genome was assembled from approximately 5.5 million reads produced by Illumina MiSeq. The 16,758 bp consisted of 13 protein-coding genes, 22 transfer RNA genes and two ribosomal RNA genes (12S and 16S). The genes and RNAs order and orientation on as well as the A + T base content (50.7%) was similar to what is found in other Teleosts. A phylogenetic tree with the most closely related species available in GenBank was built to validate L. laticaudis mitogenome.
