Arctic fox; Genetic diversity; Germplasm; SRAP marker

Sequence-related amplified polymorphism (SRAP) is a recently developed molecular marker technique that is stable, simple, reliable, and achieves moderate to high numbers of codominant markers. This study is the first to apply SRAP markers in a mammal, namely the Arctic fox. In order to investigate the genetic diversity of the Arctic fox and to provide a reference for use of its germplasm ... more

Aschersonia placenta; China; Genetic diversity; ISSR

Aschersonia placenta had been recognized as an important fungal pathogen of whiteflies. In recent years, natural occurrence of Aschersonia in whitefly populations was observed in many citrus orchards in the southern regions of China. We analyzed 60 A. placenta isolates obtained from Chinese citrus orchards, using inter-simple sequence repeats to examine the ... more

Coilia ectenes; Genetic diversity; Microsatellite marker

Coilia ectenes (Jordan and Seale 1905) is an important anadromous species that is an important resource at risk of extinction because of over-fishing, pollution, and coastal construction. To evaluate the genetic diversity of C. ectenes for use in breeding programs, elite microsatellite-enriched libraries were constructed and novel microsatellite markers were developed, ... more

Cosmos; DNA profiles; Genetic diversity; Inter-simple sequence repeat (ISSR); Random amplified polymorphic DNA (RAPD)

The genus Cosmos is native of America and is constituted by 34 species; 28 of them are endemic of Mexico. The cosmos are used as a nematicide, antimalarial, and antioxidative agent. The aim of this study was to estimate the genetic diversity among 7 cosmos species based on random amplified polymorphic DNA (RAPD) and inter-simple sequences repeats (ISSR) markers. With RAPD markers ... more

Cluster; Fenugreek; Genetic diversity; Polymorphism; RFLP; SDS-PAGE

Protein and DNA polymorphismswere surveyed among seven accessions of wild fenugreek (Trigonellafoenum-graecum L.) to estimate their genetic diversity and relationships. Samples were obtained from diverse ecogeographical areas in Saudi Arabia and Yemen. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis of seed storage protein showed genetic variations ... more

Genetic diversity; Macrobrachium nipponense; Microsatellite marker; Yellow river

To assess the genetic status of this species, the genetic diversity of wild Macrobrachium nipponense from seven geographic locations in the Yellow River basin were investigated using 20 polymorphic microsatellite DNA loci. The genetic diversity between populations was indicated by the mean number of alleles per locus and mean observed heterozygosity (H) and the expected H, which ... more

Agropyron Gaertn.; Genetic diversity; Gliadin; Phylogenetic relationship

Agropyron Gaertn. is the most important genus in Triticeae (Poaceae), which includes many forage grasses with high economic value. The genetic diversity and relationships of 36 accessions from five crested wheatgrass species were analyzed by gliadin markers. A total of 54 product bands were detected after acid polyacrylamide gel electrophoresis (A-PAGE), of which 100% were ... more

Genetic diversity; Microsatellite marker; Pampus argenteus; Population structure

In order to evaluate the germplasm resources of Pampus argenteus silver pomfret, the genetic diversity and population structure of 132 silver pomfret samples collected from the three regions (the East China Sea, the Yellow Sea and the Bohai Sea) were examined using 13 polymorphic microsatellite loci. Results indicated a high level of genetic diversity. The total number of ... 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

Cydonia oblonga; Genetic diversity; Quince; SSR

We conducted simple sequence repeat (SSR) analyses of 15 traditional quince (Cydonia oblonga) cultivars from Anatolian gene sources for molecular characterization and investigation of genetic relationships. Three pear and two apple cultivars were used as references for SSR locus data analysis and to determine allele profiles between species. Eight SSR loci that were developed ... more
