Mitochondrial DNA sequence of Mongolian redfin (Chanodichthys mongolicus)

Comparative mitochondrial genome analysis of the Mongolian redfin, Chanodichthys mongolicus (Xenocyprididae) from China reveals heteroplasmy

This study determined the mitochondrial genome (mitogenome) of Chanodichthys mongolicus from China's Qiantang River and analyzed its phylogenetic history in the Subfamily Cultrinae. Next-generation sequencing was used to obtain the mitogenome of C. mongolicus, GenBank Accession Number MZ032228. The mitochondrial genome length of C. mongolicus from China's Qiantang River is 16,622 bp. The genome contains 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs, and two central noncoding regions (the control region and the origin of light strand replication). Based on BLAST comparisons, the sequence identity of C. mongolicus MZ032228 from China's Qiantang River was 99.84% to that of Ancherythroculter wangi MG783573 from China's Nei River, 99.75% to C. mongolicus AP009060 from Russia's Black River. The phylogenetic analysis is consistent with BLAST comparisons in confirming that A. wangi MG783573 and C. mongolicus MZ032228 show a high genetic similarity. This study also confirms mitochondrial DNA heteroplasmy in C. mongolicus for the first time and documents 35 heterogeneous loci that were detected.

Mitochondrial DNA sequence of Culter compressocorpus

In this study, the complete mitochondrial genome of Culter compressocorpus was detected and annotated. The circular mtDNA molecule was 16,623 bp in length which contains 22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNA genes, and the non-coding control region (D-loop). Its total protein-coding genes content is 68.67% in whole mitochondrial genome. The mitochondrial genome can contribute to the studies on geographical distribution and genetic diversity of C. compressocorpus resources, as well as molecular phylogeny and species identification in Cyprinidae.

The complete mitochondrial genome of Mongolian redfin, Chanodichthys mongolicus (Cypriniformes: Cyprinidae): genome description and related phylogenetic analyses

Chanodichthys mongolicus is a ferocious carnivorous species in the family Cyprinidae, which has a high economic value in freshwater aquaculture species. In the present study, we report the complete mitochondrial genome of C. mongolicus, comparing with two different individuals of C. mongolicus and phylogenetic analysis with closely related species. The complete mitochondrial genome of C. mongolicus was 16,622 bp, and it contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, a control region (D-loop) and an L-strand replication origin (OL). It revealed that D-loop, ND4, ND5 and CYTB may be markers for studying conservation genetics and population genetics.
