Citrus latifolia; Genetic diversity; Genetic improvement

'Persian' acid lime (PAL) is the most important triploid commercial citrus crop planted in the world. Little is known about the genetic variability of the selections used in Brazil. Therefore, 25 genotypes originating from the PAL, and three control species, Citrus sunki, C. limon, and C. aurantiifolia, were assessed using inter-simple sequence repeat (ISSR) and ... more

The common fig (Ficus carica L.) was introduced into Mexico by Spanish Franciscan missionaries in the 16th century. It is widely assumed that Mexican figs are the Spanish cultivar Black Mission. We collected and propagated 12 fig plants from six landraces from different states in Central Mexico that represent different climate. All of them were grown in a greenhouse at ... more

Genetic differentiation; Genetic diversity; ISSRs; Machilus thunbergii; Population

The genetic diversity of 10 Machilus thunbergii populations in eastern China was analyzed using inter-simple sequence repeat markers. The populations showed high genetic diversity, with an overall population genetic diversity of 0.2343. Genetic diversity varied largely among populations, and populations with the highest genetic diversity were mainly from the eastern and western ... more

Annamocarya sinensis; Endangered species; Genetic diversity; Microsatellite; Population structure

The endangered perennial plant Annamocarya sinensis (Dode) Leroy is a tertiary relict tree restricted to southeastern China and northern Vietnam. To explore endangerment mechanisms, develop protection strategies, and guide reintroduction efforts for this species, we investigated genetic diversity and population structure by surveying 70 individuals from three distinct ... more

Anacardium humile; Anarcadium occidentale; Genetic diversity; Heterologous primer; Neotropical savannas

Microsatellite markers were transferred from the cashew, Anarcadium occidentale, to Anacardium humile (Anacardiaceae), a Neotropical shrub from the Brazilian savanna, that produces an edible nut and pseudo-fruit. We tested 14 microsatellite primers from A. occidentale on A. humile. Polymorphism of each microsatellite locus was analyzed based on 58 ... more

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

Conservation; Genetic diversity; Meliponini tribe; Microsatellite markers; Pollinators; Recôncavo Baiano

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; 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
