ABSTRACT: In this study, we report the first complete mitochondrial genome sequence of the Aquatic Coralsnake Micrurus surinamensis. The mitochondrial genome lengthis 17,375 bp, comprising 13 protein-coding genes, 2 rRNA (12S and 16S) and 22 tRNA, as well as two typical control regions. Phylogenetic analysis based upon 13 protein-coding genes showed clusters based on terrestrial and marine species.
Project description:Sinomicrurus peinani is a new species of the genus Sinomicrurus (Serpentes: Elapidae) from China and Vietnam in 2020. In this study, we successfully sequenced mitochondrial genome of an individual S. peinani. The complete mitochondrial genome of S. peinani is a circular molecule with the entire length of 19,477 bp. The base composition is T (28.1%), G (11.9%), and GC (38.5%), which contains two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, 13 protein-coding genes, one origin of replication gene (D-loop), and two non-coding control regions, an origin of light-strand replication, and a 2346 bp non-coding region between tRNA-N and tRNA-Y. A maximum-likelihood (ML) tree of S. peinani and 13 other related species was constructed. The DNA data presented here will be useful to study the evolutionary relationships and genetic diversity of S. peinani.
Project description:The complete mitochondrial genome, containing 17,526?bp, was determined from the pitviper Bothrops jararaca. It is the first mitogenome for the most medically important genus of snake in Latin America. This mitogenome has common snake mitochondrial features such as a duplicated control region that has nearly identical sequences at two different locations of the mitogenome and a translocation of tRNA-Leu (UUR). Besides, we found a translocation of the tRNA-Pro compared to Colubridae snakes. Finally, an unusual possible duplication containing a tRNA-Phe was observed for the first time and may represent a marker of the genus.
Project description:The greater green snake Cyclophiops major is a protected and colubrid species. Here, we investigated the complete mitochondrial genome of C. major. The genome is 17,217bp in size, including 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, 2 control regions, and an origin of light-strand replication. All genes are distributed on the heavy strand, except for ND6 gene and 8 tRNA genes. The AT content of the overall base composition of light strand is 59.83%, showing AT bias. Phylogenetic tree was built based on the genome of C. major and other related snakes to analyze their phylogenic relationship.
Project description:The complete mitochondrial genome (mitogenome) sequence of Laudakia sacra was determined by using a PCR-based method. The total length of mitogenome is 16,555?bp, and contains 13 typical vertebrate protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 2 control regions. Only ND6 gene and 8 tRNA genes on the L-strand other than are encoded on the H-strand. The phylogenetic tree of L. sacra and 13 other species were built. The DNA data present here will facilitate future taxonomic work of the genus Laudakia.
Project description:The complete mitochondrial genome sequence of Lycodon ruhstrati was determined by shotgun sequencing. The total genome size is 17,168 bp, and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes and 2 control regions (D-loops). Most of the genes of L. ruhstrati were distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes which were encoded on the L-strand. The phylogenetic tree of L. ruhstrati and 12 other closely related species was reconstructed. The mitogenome sequence presented here will be useful to study the evolutionary relationships and genetic diversity of L. ruhstrati.
Project description:The complete mitochondrial genome (mitogenome) sequence of Sphenomorphus indicus was sequenced and characterized by next-generation sequencing technology. The total length of mitogenome is 17,027?bp and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 2 non-coding regions (the control region and the putative L-strand replication origin). Most of the genes of S. indicus are encoded on the H-strand, except for the ND6 subunit gene and 8 tRNA genes which is distributed on the L-strand. Phylogenetic reconstruction suggested that S. indicus is the sister group of the S. incognitus within the genus Sphenomorphus. The complete mitochondrial genome sequence presented here will be useful to study the evolutionary relationships and genetic diversity of S. indicus.
Project description:The complete mitochondrial genome sequence of Takydromus septentrionalis was determined by shotgun sequencing. The total length of mitogenome is 18,304 bp, and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 2 control regions. Most of the genes of T. septentrionalis were distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes which were encoded on the L-strand. The phylogenetic tree of T. septentrionalis and 8 other closely related species was reconstructed. The phylogenetic analyses based on these mitogenomes presented here will be useful for further insights on the evolutionary relationships of Takydromus.
Project description:In this study, the complete mitochondrial genome of Plagiopholis styani was acquired and described. The mitogenome is a circular molecule of 19,669 base pairs (bp) in length including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and two control regions (D-loop), which is similar to other Colubridae snakes. The total base composition of mitochondrial DNA is A 33.0%, C 24.9%, G 12.8%, and T 29.3%. The mitochondrial genome of Plagiopholis styani contributes to revealing the phylogenetic relationships among species of the Colubridae family.
Project description:The complete mitogenome of the lizard Iphisa elegans Gray, 1851 was sequenced using a shotgun approach on an Illumina HiSeq 3000 platform, providing the first mitogenome for Gymnophthalmidae. The genome was 18,622 bp long, with 13 protein-coding genes, two rRNA (12S and 16S), and 22 tRNA, as well as the control region. A maximum likelihood phylogenetic analysis including I. elegans and all other available mitogenomes of Squamata provided a tree in accordance with previous phylogenetic relationships inferred for Squamata.
