Complete mitochondrial genome of Rivularia auriculata (Gastropoda, Viviparidae) with phylogenetic consideration.

ABSTRACT: Complete mitochondrial genome sequence of Rivularia auriculata has a circular genome of 16,552?bp, which is comprised 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. The nucleotide composition of the light strand is 43.16% of A, 26.78% of T, 20.18% of C, and 9.88% of G. All genes are encoded on the heavy strand except seven tRNA genes (Met, Tyr, Cys, Trp, Gln, Gly, and Glu) on the light strand. All the protein-coding genes start with ATC initiation codon except ND4 starts with GTG, and two types of inferred termination codons are TAA and TAG. There are 26 intergenic spacers and 4 gene overlaps. It is indicated that R. auriculata has closer genetic relationship with Viviparus chui (88.64% nucleotide sequence identity between them) than the other snail species.

Complete mitochondrial genome of the apple snail Pomacea diffusa (Gastropoda, Ampullariidae) with phylogenetic consideration.

Project description:We present the complete mitochondrial genome of Pomacea diffusa in this study. The results show that the mitochondrial genome is 16,640 bp in length, which is comprised of 13 protein-coding genes, two rRNA genes, and 21 tRNA genes. The nucleotide compositions of the light strand are 39.62% of A, 30.13% of T, 16.02% of C, and 14.24% of G. Except eight tRNA (Glu, Gly, Trp, Cys, Tyr, Met, Thr, Val) on the light strand, the rest are encoded on the heavy strand. All the protein-coding genes start with ATC initiation codon, and two types of inferred termination codons are TAA and TAG. There are 26 intergenic spacers and two gene overlaps. The phylogenetic analysis shows that P. diffusa clusters with P. canaliculata and P. maculata with high bootstrap support, which is consistent with the morphological and molecular evidence.

The complete mitochondrial genome of the freshwater snail Cipangopaludina ampullacea (Kuster, 1852) (Gastropoda: Viviparidae).

Project description:Cipangopaludina ampullacea (Küster, 1852) is a freshwater snail endemic to China. In this study, the complete mitochondrial genome of C. ampullacea was sequenced using next-generation sequencing. The mitogenome is 16,892 bp long and comprises a total of 37 genes, including 13 protein-coding genes, two rRNA genes, and 22 tRNA genes. It is consistent with the basic characteristics of other known viviparid mitochondrial genomes. Phylogenetic analysis using related species mitogenomes showed that Cipangopaludina and Margarya are mutually non monophyletic. Our study provides valuable information to reconstruct the taxonomy and evolution of viviparid snails more comprehensively.

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.

The complete mitochondrial genome and phylogenetic analysis of Littorina brevicula (Gastropoda, Littorinidea).

Project description:The complete mitochondrial genome of the Littorina brevicula was determined in this study. The complete mitogenome (mtDNA) is 16,356 base pairs (bp) in length and contains 13 protein-coding genes, two rRNA genes, and 22 tRNA genes. The control region was divided into two parts. The overall base composition of the genome in descending order was 35.33%-T, 28.41%-A, 20.43%-C, and 15.81%-G. In 13 protein-coding genes, 12 genes start with ATG, except nad5 starts with ATT. For the stop codon, seven genes end with TAA, atp6, nad41, and nad3 end with TAG. Phylogenetic analysis indicated that L. brevicula is close to Naticidea family. This study first determined the complete mitochondrial genome of L. brevicula. It would be a supplement for the genetic analysis of L. brevicula and promote the phylogenetic of Littorinidea.

The complete mitochondrial genome and phylogenetic analysis of Batillaria zonalis (Gastropoda: Batillariidae).

Project description:We determined the complete mitochondrial genome of Batillaria zonalis. The B. zonalis mitochondrial genome is 15748 bp in length, comprising 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The nucleotide composition for B. zonalis is 17.71% of C, 16.74% of G, 34.99% of T, and 30.3% of A. In 13 protein-coding genes, all genes start with ATG. For the stop codon, the cox2 gene stops with TTC, the cytb, nad1, nad2 genes stop with TAG, the other nine genes are with TAA. Of these 37 genes identified, nine protein-coding genes and six transfer RNA genes are encoded on the heavy strand and the other genes on the light strand. The phylogenetic tree was constructed based on 13 protein-coding genes of the B. zonalis and other 19 Gastropoda species, Sepia latimanus as outgroup using the Neighbour-joining method. The result showed that B. zonalis is most closely related to the Tylomelania sarasinorum in Cerithioidea. We believe that this result will be helpful for the study of population genetic and phylogenetic analysis of the family Batillariidae.
