Characterization of the complete mitochondrial genome of Diodon hystrix with phylogenetic consideration.

ABSTRACT: In this study, the complete mitochondrial genome of Diodon hystrix was sequenced and analyzed. The mitochondrial genome is 16,512?bp long and consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region. The gene order and composition of D. hystrix mitochondrial genome was similar to that of most other vertebrates. The nucleotide composition of the light strand in descending order is 28.69% of A, 31.64% of C, 23.66% of T and 16% of G. The NADH dehydrogenase subunit 6 (ND6) and 8 tRNA genes were localized in the light strand, and all other mitochondrial genes were encoded on the heavy strand. The phylogenetic analysis by maximum-likelihood (ML) method revealed that D. hystrix has the closer relationship to the Diodon holocanthus.

The complete mitochondrial genome characterization of Paratrypauchen microcephalus (Gobiiformes: Oxudercidae) and phylogenetic consideration.

Project description:The complete mitochondrial genome of Paratrypauchen microcephalus (Gobiiformes: Oxudercidae) was completely sequenced by high throughput sequencing method. The complete mitochondrial genome was 16,552?bp in length, consisted of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, a putative control region (CR), and an origin of replication on the light-strand (OL). The base composition values for the mitochondrial genome were 29.1%, 27.6%, 15.7%, and 27.6% for A, C, G, and T, respectively. The gene arrangement is identical to those in typical fishes. Phylogenetic tree based on 13 protein-coding genes shows that P. microcephalus has a close phylogenetic relationship with genus Trypauchen and belongs to Oxudercidae.

Complete mitochondrial genome of Palaemonetes sinensis and its phylogenetic consideration.

Project description:The aim of this study was to determine the complete mitochondrial genome (mitogenome) and the phylogenetic location of the Palaemonetes sinensis. The mitogenome was 15,736 bp in length, containing 22 transfer RNA genes (tRNAs), 13 protein-coding genes (PCGs), 2 ribosome RNA genes (rRNAs), and a control region (CR). The overall nucleotide composition is as follows: A, 35.69%; C, 21.66%; G, 12.39%; T, 30.26%. Nine and four PCGs were encoded on the heavy and light strands, respectively. Phylogenetic analysis suggested that P. sinensis shares a close relationship with Palaemon serenus and Palaemon capensis. These findings are helpful for better understanding the phylogenetic relationship among Caridea, as well as investigating the population genetics of P. sinensis in the future.
