The complete mitochondrial genome of Atypus karschi (Araneae, Atypidae) with phylogenetic consideration.

ABSTRACT: The complete mitochondrial genome sequence of Atypus karschi has a circular genome of 14,149 bp, comprised of 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and a control region. The nucleotide composition is 35.82% of T, 35.13% of A, 17.19% of G, and 9.16% of C. Most genes are encoded on the heavy strand except seven tRNA genes (Leu, Phe, His, Pro, Leu, Ile, Gln), four protein-coding genes (nad5, nad4, nad4l, nad1), and 16S-rRNA on the light strand. Most protein-coding genes start with TTG, ATT or ATA initiation codon except cox1, cox1's start codon cannot be determined, and three types of inferred termination codons are TAA, TAG, and an incomplete stop codon. There are four intergenic spacers and 25 gene overlaps. The phylogenetic analysis shows that A. karschi has closer genetic relationship with Cyriopagopus schmidti (von Wirth, 1991) and Phyxioschema suthepium (Raven & Schwendinger, 1898) with high bootstrap support.

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.

Project description:The complete mitogenome of Corythoxestis sunosei (GenBank accession number MT611524) is 15,511 bp in length, and harbors 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes, and an A + T-rich region. The overall base composition is A (40.04%), C (10.64%), G (7.62%), and T (41.70%), showing AT-rich feature (81.74%). ATG, ATT, CGA were initiation codons and TAA and T were termination codons. All the 22 tRNAs displayed a common cloverleaf secondary structure, except for trnS1 which lacked the dihydrouracil (DHU) arm. Phylogenetic tree based on 13 PCGs showed that C. sunosei has a close phylogenetic relationship with Gibbovalva kobusi and Cameraria ohridella and belongs to Gracillariidae.
