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

ABSTRACT: 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.

For the stop codon, the cox2 gene stops with TTC, the cytb, nad1, and nad2 genes stop with TAG, and 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. cumingi and other 19 Gastropoda species, Sepia latimanus as outgroup using the Neighbour-joining method. The tree showed that the B. cumingi is closely related to the Semisulcospira coreana in Cerithioidea. We believe that this result will be helpful for the study of population genetic and phylogenetic analysis of the family Batillariidae.

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 Omphalius rusticus (Gastropoda, Tegulidae).

Project description:The complete mitochondrial genome of the Omphalius rusticus has been determined. The complete genome is 18,067 bp and contained 13 protein-coding genes, two rRNA genes and 22 tRNA genes. The overall base composition is 33.48% (A), 33.52% (T), 15.58% (G) and 17.42% (C). The all start codon for 13 protein-coding genes is ATG and the most common termination codon is TAA. The phylogenetic tree showed that O. rusticus is most closely related to the Tectus pyramis. We suggest that this result will further supplement the genome information in mitochondria of the family Tegulidae and facilitate the study on population genetics.

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

Project description: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.

Project description:The sacoglossans are small sea slugs in the Heterobranchia. In this study, mitochondrial genome of a sacoglossan sea slug, Elysia ornata (Swainson, 1840) is analyzed and phylogenetic tree of the species in the Heterobranchia is reconstructed based on amino acid sequences of mitochondrial protein coding genes. The phylogenetic relationship analysis shows that E. ornata belongs to the monophyletic Sacoglossa in the Heterobranchia and the Sacoglossa shows sister group relationship with a lineage including Anaspidea and Siphonarioidea. This is the fourth record for the mitochondrial genome of sacoglossan sea slugs.

The closest species to S. japonica are Chromodoris magnifica and Chromodoris quadricolor that belong to the family Chromodorididae.
