RESUMO
The complete mitochondrial genome of Hemibarbus labeo BML (Cypriniformes: Cyprinidae) is 16,612 bases in length. It consists of 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes, and 1 non-coding region. Its overall nucleotide composition is A: 29.85%, G: 17.07%, T: 25.86%, and C: 27.23%, respectively, with an A + T rich feature (55.71%). The gene arrangement and organization of the mitogenome from H. labeo BML were very similar to other Cyprinidae fishes. The phylogenetic analysis showed that H. labeo BML clustered in genus Hemibarbus. These results will contribute to the taxonomy and conservation biology studies of H. labeo.
RESUMO
Northern snakehead, Channa argus, is a commercially important food fish species in China. In the present study, the complete mitochondrial genome of C.argus from the Baima Hu Lake was characterized. It is 16,558 bp in length, consist of 22 tRNA genes, 13 PCD genes, 2 rRNA genes, and 1 D-loop region. The overall base composition of the C. argus mitogenome is 27.26% A, 24.21% T, 31.58% C and 16.95% G, exhibits a similar AT bias (51.47%) feature to other vertebrate mitogenomes. The phylogenetic analysis showed that C. argus clustered in genus Channa. The present resultes provide useful information to population genetics and conservation biology studies of Channa fishes.
RESUMO
Sarcocheilichthys sinensis (Bleeker), is a small-sized benthopelagic fish with ornamental value. In the present study, the complete mitochondrial genome of S. sinensis was sequenced and determined. The complete mitogenome of S. sinensis was 16,683 bp in length, consisting of 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes, and 2 non-coding regions. The overall base composition of the S. sinensis mitogenome is 30.50% A, 26.28% T, 26.60% C, and 16.61% G, exhibiting obvious AT bias (56.79%). The phylogenetic analysis showed that S. sinensis clustered in genus Sarcocheilichthys. Present study provides useful data to population genetics and conservation biology of Sarcocheilichthys fishes.
