Endangered species; Genetic diversity; Mergus squamatus; Wintering habitat

The scaly-sided merganser (Mergus squamatus), found in temperate East Asia, has been reduced to a very small population. Central and southern China are its main wintering habitat. However, populations have declined greatly since the 1980s due to habitat loss and degradation, and poaching. To meet the urgent need for up-to-date conservation information, we examined RAPD DNA ... more

Cagaita; Cerrado; Genetic diversity; Microsatellite; Shotgun library

Microsatellite markers were developed for population genetic analyses of the Neotropical tree Eugenia dysenterica DC (Myrtaceae), after construction of a shotgun genomic library for microsatellite discovery. Nine primers were designed, of which 5 yielded amplified product. These primers were polymorphic for 97 individuals collected in 3 distinct localities. The number of alleles ... more

Bees play a key role in pollination and thereby help maintain plant diversity. The stingless bee Melipona scutellaris is an important pollinator in northeastern Brazil because it is endemic to this region. Both deforestation and timber harvesting have reduced the nesting sites for this species, thus reducing its population and range. Genetic studies may help reverse this process ... more

DNA fingerprinting; Genetic diversity; RAPD; Vicia faba

Until now, neither phenotypic nor molecular approaches have been used to characterize the landraces of Palestine faba beans (Vicia faba). We used PCR-based RAPD markers to determine the genetic diversity and relatedness among 26 Palestinian faba bean landraces (traditional farmers' varieties) from 8 localities in the West Bank, Palestine. In tests with 37 primers, 14 generated no ... more

Genetic diversity; Lamiaceae; Pogostemon cablin; SSR

Microsatellite primers were developed and optimized for patchouli (Pogostemon cablin) to characterize the patchouli Active Germplasm Bank of Universidade Federal de Sergipe. Creation of a genomic library for patchouli enabled the design of 12 microsatellite primers. Six of these microsatellites were polymorphic, revealing two well-defined groups of individuals that ... more

Genetic diversity; Microsatellite DNA; Mytilus coruscus; Population structure

Twelve new polymorphic microsatellite loci were developed for the hard-shelled mussel, Mytilus coruscus. In 32 individuals from a wild population of coastal Zhoushan, Zhejiang Province, China, the number of alleles at these loci varied from 3 to 15, with a mean of 5.667. The mean observed and expected heterozygosities were 0.6927 and 0.6591, respectively. Among these polymorphic ... more

Genetic diversity; Jatropha curcas; Selective accuracy; Ward-MLM

The use of efficient breeding methods depends on knowledge of genetic control of traits to be improved. We estimated genetic parameters, selection gain, and genetic diversity in physic nut half-sib families, in order to provide information for breeding programs of this important biofuel species. The progeny test included 20 half-sib families in 4 blocks and 10 plants per plot. The mean ... more

Fifteen new polymorphic microsatellite loci were developed for the cuttlefish Sepiella maindroni. In 32 individuals from a wild population of coastal Ningde, Fujian Province, China, the number of alleles at these loci varied between 2 and 12, with an average of 5.86. The mean observed and expected heterozygosities were 0.6917 and 0.5993, respectively. Among these polymorphic ... more

Chickpea; DNA fingerprinting; Genetic diversity; Hybrids; RAPD markers

The intensity of genetic diversity amongst chickpea genotypes and their crosses is unknown. The current study investigated the genetic diversity of chickpea genotypes and their F1 crosses by using random amplified polymorphic DNA (RAPD) markers. We assessed the variation among six chickpea genotypes and 15 F1 crosses with the RAPD markers. The six parents and their ... more

The genetic diversity among 80 Vitis materials including 62 indigenous accessions of 17 wild Vitis species in China and 7 interspecific hybrids, 10 V. vinifera L. cultivars, and 1 V. riparia Michaux were evaluated by simple sequence repeat and sequence-related amplified polymorphism markers. A total of 10 simple sequence repeat primers and 11 sequence- ... more
