Claea dabryi is a small bottom-dwelling fish that is endemic to the upper stream of the Yangtze River. In this study, we successfully sequenced the first mitochondrial genome of C. dabryi. The mitogenome is 16 569 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region (D-loop). Most of the genes are encoded on the heavy strand, except for eight tRNAs (tRNAGln, tRNAAla, tRNAAsn, tRNACys, tRNATyr, tRNASer, tRNAGlu, and tRNAPro) and ND6 gene. In this paper, we utilized 12 protein-coding genes of C. dabryi and other 11 closely species to construct the species phylogenetic tree to verify the accuracy of C. dabryi. [ABSTRACT FROM AUTHOR]

Hemiculterella sauvagei, a Chinese minnow endemic to the upper Yangtze River, is an important part of the aquatic ecosystem and plays a vital ecological role in maintaining aquatic biodiversity. In this study, we provide the first mitochondrial genome ofH. sauvagei. The complete mitochondrial genome ofH. sauvageiis 16618 bp in length, containing 13 protein-coding genes, two rRNA genes (12 S and 16 S rRNA), 22 tRNA genes and a non-coding control region (D-loop). The gene nucleotide composition ofH. sauvageiis A = 29.9%, T = 27.0%, C = 17.4% and G = 25.6%, with a slight AT bias of 56.9%. The complete mitochondrial genome ofH. sauvageiwould be useful for further studies on genetic diversity and molecular phylogenetic relationship of the subfamily Cultrinae. [ABSTRACT FROM AUTHOR]

Schizopygopsis pylzovi, an endemic species in the Qinghai-Tibetan Plateau, has a unique ability to adapt to the extreme ecological condition of the plateau. In this study, we successfully sequenced the first mitochondrial genome ofS. pylzovi. The mitogenome is 16,814 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region (D-loop). The overall base composition of the heavy strand (H-strand) is 28.3% A, 26.1% C, 18.6% G, and 27.0% T, with a slight AT bias of 55.3%. Most of the genes are encoded on H-strand, except for eight tRNAs (tRNAGln, tRNAAla, tRNAAsn, tRNACys, tRNATyr, tRNASer, tRNAGluandtRNAPro) andND6genes. [ABSTRACT FROM AUTHOR]

Schizopygopsis chengi baoxingensisis endemic to the Baoxing River in China and may become an endangered species due to its very narrow habitat and the construction of hydropower dams. In this study, we successfully sequenced the first mitochondrial genome ofS. c. baoxingensis. The mitogenome is 16,787 bp in length, containing 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region (D-loop). The overall base composition of the H-strand is 28.5% A, 26.2% T, 18.4% C, and 26.9% G, with a slight AT bias of 54.7%. The sequenced mtDNA genome ofS. c. baoxingensisis similar in gene arrangement to that of other cyprinidaes except for a 191 bp non-coding region found betweentRNAThrandtRNAPro.

Garra kempi, a small-sized economic fish, is mainly distributed in Tibet of China. In this study, we successfully sequenced the first mitochondrial genome ofG. kempi. The mitogenome is 17 104 bp in length, containing 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and 2 control regions (D-loop). Unlike the typical mitochondrial genome organization in vertebrate, thetRNAProgene ofG. kempiis located between two control regions, and a 246 bp repeat unit is identified in the second control region. In this paper, we utilized 12 protein-coding genes ofG. kempiand other 10 closely species to construct the species phylogenetic tree to verify the accuracy ofG. kempi. [ABSTRACT FROM AUTHOR]

The beardless sucking bard,Garra imberba, is an important economic freshwater fish with very limited yield. In this study, we successfully sequenced the first mitochondrial genome ofG. imberbaby PCR. The mitogenome is 16,600 bp in length, containing 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region (D-loop). The overall base composition of the H-strand is 31.5% A, 26.7% T, 16.1% C, and 25.8% G, with a slight AT bias of 58.2%. Most of the genes are encoded on heavy strand, except for eight tRNAs (tRNAGln, tRNAAla, tRNAAsn, tRNACys, tRNATyr, tRNASer, tRNAGlu and tRNAPro) andND6genes. [ABSTRACT FROM PUBLISHER]

Xenophysogobio nudicorpais one member of the genus containing two species only, which is a specialized lineage of gobiobotine fishes. In this study, we provide the first mitochondrial genome ofX. nudicorpa. The complete mitochondrial genome ofX. nudicorpais 16,616 bp in length, containing 13 protein-coding genes, two rRNA genes (12 S and 16 S rRNA), 22 tRNA genes and a noncoding control region (D-loop). The gene nucleotide composition ofX. nudicorpais 30.5% A, 26.0% T, 16.8% C and 26.7% G, with a slight AT bias of 56.5%. The complete mitochondrial genome ofX. nudicorpawould be useful for further studies on genetic diversity and molecular phylogenetic relationship of the subfamily Gobiobotinae.
