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

Conservation biology; Genetic diversity; Microsatellite markers; Platycodon grandiflorum

The balloon flower (Platycodon grandiflorum A. DC.) is a perennial flowering plant of the Campanulaceae family; it is the only member of the genus Platycodon. Information on the genetic diversity of balloon flower populations is of great importance for the conservation and germplasm utilization of this flowering plant. Twenty-two polymorphic microsatellite loci were ... more

conservation genetics; Genetic diversity; Houbara bustard; Microsatellite markers

The Houbara bustard (Chlamydotis undulata) is a threatened avian species that is rapidly declining throughout its range, especially in North Africa, Asia and the Canary Islands. We examined the population structure and genetic variation for the three Houbara subspecies C. undulata undulata, C. u. fuertaventurae and C. u. macqueenii. A total of 266 birds ... more

Chinese pony populations; Genetic diversity; Genetic relationship; Microsatellite markers

China is one of the principal origins of ponies in the world. We made a comprehensive analysis of genetic diversity and population structure of Chinese ponies based on 174 animals of five indigenous Chinese pony breeds from five provinces using 13 microsatellite markers. One hundred and forty-four alleles were detected; the mean number of effective alleles among the pony breeds ranged ... more

Gene flow; Genetic conservation; Genetic diversity; Microsatellite marker; Population differentiation; Wolf fruit

Solanum lycocarpum is a woody tree widely distributed in the Cerrado that reaches high population densities in disturbed environments. We examined the genetic diversity and population differentiation of six S. lycocarpum populations with different degrees of human disturbance in order to determine if they are negatively affected by anthropogenic activity. Three ... more

Elymus sibiricus; Genetic diversity; Population structure; RAPDs

Genetic diversity of Elymus sibiricus (Poaceae) was examined in eight populations from the southeast Qinghai-Tibet Plateau. We detected 291 RAPD polymorphic loci in 93 samples. The percentage of polymorphic bands (PPB) was 79%. Genetic diversity (HE) was 0.264, effective number of alleles (NE) was 1.444, Shannon’s information ... more

Genetic diversity; Hemarthria compressa; Population structure; SRAP

Hemarthria compressa is one of the most important and widely utilized forage crops in south China, owing to its high forage yield and capability of adaptation to hot and humid conditions. We examined the population structure and genetic variation within and among 12 populations of H. compressa in south China using sequence-related amplified polymorphism (SRAP) markers. ... more

Climatic factors; Genetic diversity; Geographic information system; Random amplified polymorphic DNA; Stipa breviflora

Genetic diversity of Stipa breviflora populations in the Inner Mongolian grasslands of China and its possible correlation with climatic factors was examined using geographic information systems and random amplified polymorphism DNA analysis. A total of 308 bands were produced with 28 arbitrary decamer oligonucleotide. Three major findings were demonstrated. First, the genetic ... 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
