Onychostoma ovale
(Pellegrin & Chevey, 1936) is an endemic cyprinid fish that is widely inhabited in southern China, Vietnam, and Laos. In the present study, we first reported the complete mitochondrial genome of
O. ovale
. The mitogenome contained 16,600 bp with AT content of 56.2% and comprised of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region (D-loop). Phylogenetic analyses suggested that
Onychostoma
species formed two major clades and the subspecies of
O. ovale
had close relationship with
O. rarum
. The mitochondrial genome of
O. ovale
provided a key aid for population genetics and phylogenetic inferences of
Onychostoma
in future research.
The sharpbelly,
Hemiculter leucisculus
(Basilewsky, 1855) is a small cyprinid fish that has a wide distribution in East Asia. In this study, we characterized the complete mitochondrial genome of
H. leucisculus
in Hainan Island using Illumina MiSeq platform. The mitogenome contained 16,621 bp with AT content of 56.2%. The mitogenome of
H. leucisculus
comprised 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and one control region (D-loop). Phylogenetic analyses indicated that
H. leucisculus
in the Hainan Island formed independent lineage and the species of
H. leucisculus
might be a paraphyletic taxon.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
