M. Du, Yin, S. W., Niu, B. Z., Du, M., Yin, S. W., and Niu, B. Z., Phylogenetic relationships of twenty Gymnothorax species based on cytochrome b sequence data, vol. 15, p. -, 2016.

To study the phylogenetic relationships of the genus Gymnothorax (moray eels) distributed in South China Sea, polymerase chain reactions were performed, and the amplification products were sequenced by cloning into the PMD18T-vector (TaKaRa). The entire gene sequences encoding cytochrome b (1140 bp) for 16 Gymnothorax (G. flavimarginatus, G. meleagris, G. undulates, G. reticularis, G. reevesi, G. melanospilus, G. rueppeliae, G.

Mitochondrial tRNALeu(CUN) A12307G variant may not be associated pancreatic cancer

Y. Li, Huang, A. W., Chen, Y. Z., Yang, W. J., Zhou, M. T., Sun, H. W., Li, Y., Huang, A. W., Chen, Y. Z., Yang, W. J., Zhou, M. T., and Sun, H. W., Mitochondrial tRNALeu(CUN) A12307G variant may not be associated pancreatic cancer, vol. 15, p. -, 2016.

Mitochondrial DNA mutations that lead to mitochondrial dysfunction have long been proposed to play important roles in the development of pancreatic cancer. Of these, alterations to mitochondrial tRNA genes constitute the largest group. Most recently, a variation at position 12307 in the gene encoding tRNALeu(CUN) has been reported to be associated with this disease. However, the molecular mechanism underlying this relationship remains poorly understood.

Population genetic structure of critically endangered salamander (Hynobius amjiensis) in China: recommendations for conservation

J. Yang, Chen, C. S., Chen, S. H., Ding, P., Fan, Z. Y., Lu, Y. W., Yu, L. P., Lin, H. D., Yang, J., Chen, C. S., Chen, S. H., Ding, P., Fan, Z. Y., Lu, Y. W., Yu, L. P., and Lin, H. D., Population genetic structure of critically endangered salamander (Hynobius amjiensis) in China: recommendations for conservation, vol. 15, p. -, 2016.

Amji’s salamander (Hynobius amjiensis) is a critically endangered species (IUCN Red List), which is endemic to mainland China. In the present study, five haplotypes were genotyped for the mtDNA cyt b gene in 45 specimens from three populations. Relatively low levels of haplotype diversity (h = 0.524) and nucleotide diversity (π = 0.00532) were detected. Analyses of the phylogenic structure of H. amjiensis showed no evidence of major geographic partitions or substantial barriers to historical gene flow throughout the species’ range.

Structure of mitochondrial DNA control region and genetic diversity of Moschus berezovskii populations in Shaanxi Province

H. Feng, Feng, C. L., Huang, Y., Tang, J., Feng, H., Feng, C. L., Huang, Y., Tang, J., Feng, H., Feng, C. L., Huang, Y., and Tang, J., Structure of mitochondrial DNA control region and genetic diversity of Moschus berezovskii populations in Shaanxi Province, vol. 15, p. -, 2016.

In China, Moschus berezovskii (forest musk deer), a first-class national protected animal, was earlier widely distributed. However, wild populations of the forest musk deer have declined because of human activity and habitat loss. In order to gather useful information for its conservation and management, we investigated the genetic diversity and population structure of this species by analyzing a 632-bp fragment of mitochondrial DNA (mtDNA) control region in three wild populations in Shaanxi Province, China.
