Abstract:
We determined the complete mitochondrial DNA
sequences for two species of surface- and cave-dwelling-cyprinid fishes,
Sinocyclocheilus grahami and S. altishoulderus. Sequence comparison of
13 protein-coding genes shows that the mutation pattern of each single
gene is quite similar to those of other vertebrate animal species. Analysis
of the ratios of Ka/Ks at these loci between Sinocyclocheilus and two
other cyprinid species (Cyprinus carpio and Procypris rabaudi) show that
Ka/Ks ratios are differed, consistent with purifying selection and
variation in functional constraint among genes. Bayesian analysis and
maximum likelihood analysis of the concatenated mitochondrial protein sequences for 14 cyprinid taxa support the monophyly of the family
Cyprininae, and further confirm the monophyly of the genus
Sinocyclocheilus. The two Sinocyclocheilus species fall within the
Cyprinion-Onychostoma lineage, including Cyprinus, Carassius, and
Procypris, rather than among the Barbinae, as previously suggested on
morphological grounds. KW: Sinocyclocheilus grahami, Sinocyclocheilus
