The complete mitochondrial genome of Percocypris retrodorsalis (Teleostei, Cypriniformes) in Nujiang River: characterization and phylogenetic position.

ABSTRACT: Percocypris retrodorsalis is an endemic species found in Nujiang River and Lantsang. In this study, the complete mitochondrial genome of P. retrodorsalis was determined. The circular mitochondrial genome was 16,576 bp long, containing 13 protein-coding genes, two ribosomal RNA genes (rRNA), 22 transfer RNA (tRNA) genes, an origin of light-strand replication (OL), and one displacement loop locus (D-loop). Most genes were encoded on the heavy strand except for ND6 and eight tRNA genes. There were 11 regions of gene overlaps totaling 29 bp and seven intergenic spacer regions totaling 37 bp. The phylogenetic analyses were performed on the concatenated dataset of 28 protein-coding genes (PCGs), and the fishes of genus Percocypris may have a close relationship with Schizothoracins (Schizothoracinae) compared to other Cyprinidae fishes.

In this study, the entire mitogenome sequence of the H. pycnolepis has been sequenced by using sanger sequencing method. The circular mitochondrial genome was 16,570 bp in length and contained of 13 protein-coding genes, two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, an origin of light-strand replication (OL), and one displacement loop locus (D-loop). The overall base composition was 30.1% A, 26.4% T, 26.8% C, and 16.7% G with 56.6% AT content. Most genes were encoded on the heavy strand except for ND6 and eight tRNA genes. There were 11 regions of gene overlaps totaling 29 bp and 7 intergenic spacer regions totaling 37 bp. Its structure type was similar to the mitogenome of Cobitidea fishes. Phylogenetic analysis with 33 complete mitogenomes of Cobitidea and 2 Macrognathus fishes in the family of Mastacembelidae suggested that Homatula species clustered as one monophyletic clade and Homatula was closely related to Schistura. Mitogenome information from this study could be a useful basis for conservation and phylogenetics of this species.

The complete mitochondrial genome sequence of Triplophysa stenura (Teleostei, Cypriniformes): genome characterization and phylogenetic analysis.

Project description:The nemacheilid genus Triplophysa is widely distributed in the Qinghai-Tibet Plateau and its adjacent areas. The complete mitochondrial genome of the loach Triplophysa stenura collected from the Peigucuo Lake was sequenced. The genome was 16,569 bp in length, including 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a non-coding control region (D-loop). Most of the genes were encoded on the heavy strand, except for ND6 and eight tRNA genes. The overall base composition of T. stenura was 27.8% for A, 28.4% for T, 25.4% for C, 18.4% for G, with a slight A + T rich feature (56.2%). Phylogenetic analyses showed that all Triplophysa species clustered together and T. stenura formed a sister relationship with T. tibetana. The complete mitogenome data of T. stenura would provide essential information in understanding phylogenetic relationships among Triplophysa species.

Characterization of the complete mitochondrial genome of Aphyocypris chinensis (Cypriniformes, Xenocyprididae), and its phylogenetic position in Cypriniformes.

Project description:Aphyocypris chinensis Günther, 1868 is a small freshwater fish of the family Xenocyprididae (Cypriniformes). In this study, we determined its complete mitochondrial genome and phylogenetic position in Cypriniformes. The complete mitochondrial genome is 16,608 bp in size, containing 13 protein-coding genes, two RNAs, 22 tRNAs, and a control region. It has the typical vertebrate mitochondrial gene arrangement. Our mitogenomic phylogeny revealed that A. chinensis belongs to Xenocyprididae, rather than Danionidae. This mitogenome information could play an essential role in resolving the conflict over its current taxonomic status in Cypriniformes.
