AFLP; Colombia; Genetic diversity; Heliconia; Phylogenetic relationships

Researchers have classified the Heliconia genus as a group of highly variable and diverse plants. Species and cultivars are visually differentiated primarily on the basis of the color and size of inflorescence bracts. At taxonomic level, flower type (parabolic, sigmoid, or erect) and size are taken into account. The vast morphological diversity of heliconias at intra-specific, ... more

Anhui; Genetic diversity; ISSR-PCR; Phytophthora capsici

Phytophthora capsici is a plant pathogenic oomycete that damages numerous crops worldwide. Consequently, interest in research on the genetic structure of this species has grown in recent decades. However, there is little information about P. capsici in eastern China. We investigated the genetic diversity of P. capsici isolates from three large regions of Anhui ... more

Genetic diversity; Molecular markers; Morphological traits; Robinia pseudoacacia; Spaceflight

The black locust (Robinia pseudoacacia) is a forest legume that is highly valued as a honey plant and for its wood. We explored the effect of short-term spaceflight on development of R. pseudoacacia seedlings derived from seeds that endured a 15-day flight; the genetic diversity and variation of plants sampled from space-mutagenized seeds were compared to plants from ... more

Complex hypervariable repeats; Freshwater fish; Genetic diversity; Hatchery program; Population genetic structure; Prochilodus costatus

We used complex hypervariable repeats to evaluate the genetic diversity and structure of Prochilodus costatus (Characiformes), an ecologically and economically important species endemic to the São Francisco River basin. Hydroelectric dams along the river have led to population fragmentation, which can limit gene flow. Restocking from hatcheries has been used to repopulate ... more

cluster analysis; Genetic diversity; Lagerstroemia; SSR

Lagerstroemia (crape myrtle) are famous ornamental plants with large pyramidal racemes, long flower duration, and diverse colors. However, little is known about the genetic structure and diversity of germplasm in Lagerstroemia. We genotyped 81 L. indica cultivars, five other species of Lagerstroemia, and 10 interspecific hybrids using 30 simple sequence ... more

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

Anthropogenic impact; Genetic diversity; Mytilus galloprovincialis; Pollution; Population structure; RAPD

Despite the great commercial and economic importance of mussels, Mytilus galloprovincialis (Bivalvia, Mollusca) in Greece, little information is available concerning their population genetic structure. We used RAPD markers to examine genetic differentiation and potential impact of aquaculture practices and other anthropogenic activities on the genetic structure of two cultivated ... 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
