Genetic diversity; Genetic structure; Haliotis discus hannai; Microsatellites; Pacific abalone

Populations of the Pacific abalone, Haliotis discus hannai, have been severely overexploited over the past few decades in Korea. Information regarding the levels of genetic variability and structure within populations is insufficient for the development of effective strategies for conservation of genetic diversity of this species. To assess the genetic status of this species, we ... more

Control region; Genetic diversity; Genetic structure; Mitochondrial DNA; Setipinna taty

The genetic diversity of Setipinna taty, which is commercially fished in the China Sea, was studied based on mitochondrial DNA control region sequences. PCR was used to amplify the control region fragment in 100 individuals of S. taty collected from Weihai (WH), Yantai (YT), Zhoushan (ZS), Xiangshan (XS), and Ninghai (NH) in China. A control region fragment of 656 bp was ... more

Diversity index; Genetic diversity; Genetic structure; Saccharum spontaneum; SRAP

Saccharum spontaneum is a wild sugarcane species that is native to and widely distributed in China. It has been extensively used in sugarcane breeding programs, and is being tested for the development of bioenergy cultivars. In order to provide basic information for the exploitation of this species, we analyzed genetic variation among and within native S. spontaneum ... more

Dipsacus asperoides; Genetic diversity; Genetic structure; Inter-simple sequence repeat

In order to evaluate the genetic diversity and genetic structure of wild Dipsacus asperoides, we surveyed genetic polymorphisms in 288 individuals from 12 populations using ISSR. A total of 240 bands were amplified, among which 190 were polymorphic loci. At the species level, genetic diversity was found to be abundant: PPB = 79.17%, NE = 1.2152, H ... more

Genetic diversity; Genetic structure; Mandarin fish (Siniperca chuatsi); Microsatellite

In this report, 10 polymorphic microsatellites were applied to assess the genetic diversity and genetic differentiation of 5 consecutive breeding generations of mandarin fish, Siniperca chuatsi (Basilewsky). The results from total number of alleles, average polymorphism information content, and average homozygosity and heterozygosity showed that the genetic diversity of the ... more

Genetic characterization; Genetic diversity; Genetic structure; Genome comparisons

Genetic characterization among Red Junglefowl (GS, Gallus gallus spadiceus), Thai indigenous chicken (TIC, Gallus domesticus) and commercial lines has been widely used for studies of genealogical origin, genetic diversity, and effects of selection. We compared the efficiency of genetic characterization of chicken populations that had been under different intensities of ... more

Genetic diversity; Genetic structure; SSR

Nine microsatellite loci were isolated from the genome of Laodelphax striatellus (Homoptera: Delphacidae) by constructing (TC)6(AC)5 and (AG)6(AC)5 compound SSR-enriched libraries using suppression-PCR procedures. These loci were found to be highly polymorphic, with 13 to 30 alleles per locus in the three populations that we investigated ... more

Genetic structure; Microsatellite markers; Trachinotus ovatus

To evaluate the population genetic diversity of the ovate pompano, we isolated and characterized 19 microsatellite markers using a (CA)13-enriched genomic library. Polymorphism was assessed in 30 individuals from a single population collected from the Daya Bay Aquaculture Center, Guangdong, China. The number of alleles per locus ranged from 2 to 18 with an average of 7.8. The ... more

Castanopsis hystrix; Genetic structure; Microsatellite markers

Castanopsis hystrix is one of the most important and dominant species in evergreen broad-leaved forests in subtropical China. However, the population of this species undergone severe decline because of deforestation over the past 2 decades. For both conservation and forestry management, it is essential to develop molecular markers for C. hystrix. We identified ... more

American cattle breeds; Brazilian cattle; Genetic diversity; Microsatellite markers; Population structure

The Brazilian cattle population is mainly composed of breeds of zebuine origin and their American derivatives. Comprehensive knowledge about the genetic diversity of these populations is fundamental for animal breeding programs and the conservation of genetic resources. This study aimed to assess the phylogenetic relationships, levels of genetic diversity, and patterns of taurine/zebuine ... more
