Population Structure
A rapid screening of ancestry for genetic association studies in an admixed population from Pernambuco, Brazil
Authors: A.V.C. Coelho, R.R. Moura, C.A.J. Cavalcanti, R.L. Guimar�£es,P. Sandrin-Garcia, S. Crovella and L.A.C. Brand�£o
Genetic association studies determine how genes influence traits. However, non-detected population substructure may bias the analysis, resulting in spurious results. One method to detect substructure is to genotype ancestry informative markers (AIMs) besides the candidate variants, quantifying how much ancestral populations contribute to the samples&rsquo..

Microsatellite markers reveal genetic divergence among wild and cultured populations of Chinese sucker Myxocyprinus asiaticus
Authors: W.W. Cheng, D.Q. Wang, C.Y. Wang, H. Du and Q.W. Wei
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 e..

Genetic diversity and population structure of Castanopsis eyrei based on simple sequence repeat markers
Authors: L.H. Mao, X.L. Zhou and Y.M. Fang
Castanopsis eyrei (Fagaceae) is one of the dominant tree species in mid-subtropical, evergreen, broad-leaved forests. We obtained 14 pairs of simple sequence repeat (SSR) primers from previous studies, which were used to analyze 90 C. eyrei individuals from three populations at different altitudes. Low heterozygosity was detec.. Read More»

Conservation genetics of Annamocarya sinensis (Dode) Leroy, an endangered endemic species
Authors: Z.Y. Zhang, X.M. Pang, J.W. Han, Y. Wang and Y.Y. Li
The endangered perennial plant Annamocarya sinensis (Dode) Leroy is a tertiary relict tree restricted to southeastern China and northern Vietnam. To explore endangerment mechanisms, develop protection strategies, and guide reintroduction efforts for this species, we investigated genetic diversity and population structure by surveying 70 individuals from t..

Population structure and demographic history of Sicyopterus japonicus (Perciformes; Gobiidae) in Taiwan inferred from mitochondrial control region sequences
Authors: Y.M. Ju, C.H. Hsu, L.S. Fang, H.D. Lin, J.H. Wu, C.C. Han, I.-S. Chen and T.Y. Chiang
The amphidromous goby Sicyopterus japonicus is distributed throughout southern Taiwan and Japan. Larvae of this freshwater fish go through a long marine stage. This migratory mode influences population genetic structure. We examined the genetic diversity, population differentiation, and demographic history of S. japonicus based on the mitochondrial DNA co..

Population structure of the blood clam (Tegillarca granosa) in China based on microsatellite markers
Authors: Y.J. Wang, Q.G. Zeng and L.N. Xu
The blood clam, Tegillarca granosa, is widely cultivated in China. We isolated 6 microsatellite loci from T. granosa and used them to investigate genetic diversity and population structure of 5 widely distributed populations of blood clam collected from eastern and southeastern China. The allele number per locus varied from 4 to 9, and the polymorphism in.. Read More»

Paeonia (Paeoniaceae) expressed sequence tag-derived microsatellite markers transferred to Paeonia delavayi
Authors: D.X. Wang, H. Ma, Y.L. Zhang, A.A. Duan, W.J. Li and Z.H. Li
Paeonia Franchet contains approximately 30 species of perennial herbs and is the only member of the family Paeoniaceae. Paeonia delavayi is an endangered ornamental plant that has a compound flower color and is endemic to southwest China. Its optimal habitats have been fragmented and its population size has greatly decreased as a result of human activitie.. Read More»

Development and characterization of microsatellite markers of the eastern keelback mullet (Liza affinis)
Authors: L. Liu, T.X. Gao, Z.Q. Han, C.H. Li, D.R. Sun and N. Song
Twenty-four polymorphic microsatellite loci were isolated and characterized for Liza affinis using a (GT)13-enriched genomic library. The number of alleles per locus ranged from 3 to 9, with a mean number of 6.250. The observed and expected heterozygosities ranged from 0.417 to 1.000 and from 0.550 to 0.861, with an average of..
