W., “Microsatellite markers reveal genetic divergence among wild and cultured populations of Chinese sucker Myxocyprinus asiaticus”, vol. 15, p. -, 2016.

Studies of genetic diversity and genetic population structure are critical for the conservation and management of endangered species. The Chinese sucker Myxocyprinus asiaticus is a vulnerable monotypic species in China, which is at a risk of decline owing to fluctuations in effective population size and other demographic and environmental factors. We screened 11 microsatellite loci in 214 individuals to assess genetic differentiation in both wild and cultured populations.

Population genetic structure of Myzus persicae nicotianae (Hemiptera: Aphididae) in China by microsatellite analysis

C. Zhao, Yang, X. M., Tang, S. H., Xu, P. J., Bian, W. J., Wang, X. F., Wang, X. W., and Ren, G. W., “Population genetic structure of Myzus persicae nicotianae (Hemiptera: Aphididae) in China by microsatellite analysis”, vol. 14, pp. 17159-17169, 2015.

The tobacco aphid, Myzus persicae nicotianae (Hemiptera: Aphididae), is an important agricultural pest that feeds on host plants and transmits plant viruses in China. To effectively control this pest, we investigated the genetic variation and genetic structure of 54 populations of tobacco aphids collected in China, using five microsatellite loci.

Genetic characterization of red-colored heartwood genotypes of Chinese fir using simple sequence repeat (SSR) markers

H. J. Duan, Hu, R. Y., Wu, B., Chen, D. X., Huang, K. Y., Dai, J., Chen, Q., Wei, Z. C., Cao, S., Sun, Y. H., and Li, Y., “Genetic characterization of red-colored heartwood genotypes of Chinese fir using simple sequence repeat (SSR) markers”, vol. 14, pp. 18552-18561, 2015.

The present study investigated the genetic characterization of red-colored heartwood Chinese fir [Cunninghamia lanceolata (Lamb.) Hook.] in Guangxi using 21 simple sequence repeat (SSR) markers and analyzes of the genetic variation (N = 149) in samples obtained from five sites in Guangxi Province, China. The number of different alleles and the Shannon’s information index per locus ranged from 3 to 12 and from 0.398 to 2.258 with average values of 6 and 1.211, respectively, indicating moderate levels of genetic diversity within this germplasm collection.

Selection of an effective microsatellite marker system for genetic control and analysis of gerbil populations in China

X. Y. Du, Li, W., Sa, X. Y., Li, C. L., Lu, J., Wang, Y. Z., and Chen, Z. W., “Selection of an effective microsatellite marker system for genetic control and analysis of gerbil populations in China”, vol. 14, pp. 11030-11042, 2015.

Although gerbils have been widely used in many areas of biological research over many years, there is currently no effective genetic quality control system available. In the present study, we sought to establish a microsatellite marker system for quality control and con­ducted an optimized analysis of 137 microsatellite loci in two labora­tory gerbil populations and one wild population.
