Transcriptome analysis and gene expression analysis related to salinity-alkalinity and low temperature adaptation of .

is a common species of , and it is distributed in Shule river of Hexi Corridor, of Gansu province in China. In order to enrich gene database resources and explore the environment adaptation of , fifteen tissues were collected from three adult for transcriptome sequencing and assembly. Nine major international gene annotation databases (NR, COG, egg_NOG, TrEMBL, Pfam, KOG, Swiss prot, KEGG and Gene Ontology) were utilized to annotate unigenes.

A Chromosome-Scale Reference Assembly of a Tibetan Loach, .

Cobitoidea is one of the two superfamilies in Cypriniformes; however, few genomes have been sequenced for Cobitoidea fishes. Here, we obtained a total of 252.90 Gb of short Illumina reads and 31.

Mitogenomic perspectives on the origin of Tibetan loaches and their adaptation to high altitude.

Tibetan loaches are the largest group of Tibetan fishes and are well adapted to the Tibetan Plateau. To investigate the origin of Tibetan loaches and their adaptations to the Tibetan Plateau, we determined 32 complete mitochondrial genomes that included 29 Tibetan loach species, two Barbatula species and Schistura longus. By combining these newly determined sequences with other previously published mitochondrial genomes, we assembled a large mitogenomic data set (11,433 bp) of 96 species in the superfamily Cobitoidea, to investigate the phylogenetic status of the genus Triplophysa.

Evidence for Adaptation to the Tibetan Plateau Inferred from Tibetan Loach Transcriptomes.

Triplophysa fishes are the primary component of the fish fauna on the Tibetan Plateau and are well adapted to the high-altitude environment. Despite the importance of Triplophysa fishes on the plateau, the genetic mechanisms of the adaptations of these fishes to this high-altitude environment remain poorly understood. In this study, we generated the transcriptome sequences for three Triplophysa fishes, that is, Triplophysa siluroides, Triplophysa scleroptera, and Triplophysa dalaica, and used these and the previously available transcriptome and genome sequences from fishes living at low altitudes to identify potential genetic mechanisms for the high-altitude adaptations in Triplophysa fishes.

Sequence and organization of the complete mitochondrial genome of Schizothorax davidi (Teleostei: Cypriniformes: Cyprinidae).

In this study, we determined the complete mitochondrial genome sequence of Schizothorax davidi. The length of the genome is 16,577 bp, which contains 13 protein coding genes, 22 transfer RNAs, two ribosomal RNAs, and two non-coding regions: control region (D-loop) and origin of light-strand replication (OL). The complete mitochondrial DNA sequence of S.

Characterization of the complete mitochondrial genome of Gymnocypris chilianensis (Teleostei: Cypriniformes: Cyprinidae).

The complete mitochondrial DNA sequence of Gymnocypris chilianensis was determined and analyzed. The mitogenome of G. chilianensis is 16,667 bp long, containing 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 2 non-coding regions: control region (D-loop) and origin of light-strand replication (OL).
