Brazil; Microsatellites; Mollusca; Mytilidae; Perna perna; Population genetics

Perna perna is the most important cultivated mussel of Santa Catarina, Brazil, sustaining an important economic input for many local families. Natural stocks of P. perna are depleted by the extraction of adults and seeds for consumption and culture. The aim of the present study was to use the microsatellite locus pms-2 to study the variation of the genetic ... more

DNA; DYS464; Microsatellites; Population genetics; Worldwide populations; Y-chromosome

Of all DNA markers on the human Y-chromosome, the tetra-local Y-linked microsatellite DYS464 is the most polymorphic. We genotyped DYS464 in 677 male samples collected worldwide, maintained in the HGDP-CEPH Human Genome Diversity Cell Line Panel. Fourteen different alleles were found, with allele lengths varying from 9 to 23 repeats. One hundred and seventy-five ... more

Medicinal plant; Microsatellites; Population genetics; Tetrastigma hemsleyanum

Tetrastigma hemsleyanum (Vitaceae) is an endangered medicinal plant endemic to China. Because of its widely known efficacy for treating many health problems, wild resources of this species are currently undergoing a rapid decline. Few studies have been conducted examining the population genetics or development of microsatellite loci for this plant. In this study, 14 ... more

Cunninghamia lanceolata; Cupressaceae; Genetic conservation; Microsatellites; Population genetics

As a result of human activities, wild populations of Cunninghamia lanceolata (Cupressaceae) have sharply declined in recent years. The development and implementation of a valid conservation strategy require a clear understanding of the genetic makeup of this species. Eleven polymorphic microsatellite loci were isolated and characterized from samples of 52 individuals from the ... more

Genetic variability; Microsatellites; Nuclear molecular markers; Population structure; Wading bird

Roseate Spoonbills (Platalea ajaja, Linnaeus) are wading birds present in two of the most important Brazilian wetlands: the Pantanal wetlands and Rio Grande do Sul marshes. Natural populations of these species have not been previously studied with variable nuclear molecular markers. In order to support decision making regarding the management and conservation of these populations, we ... more

matUPD15; Microsatellite analysis; Microsatellites; Prader-Willi syndrome

Prader-Willi syndrome (PWS) is a multisystemic disorder caused by the loss of expression of paternally transcribed genes in the PWS critical region of chromosome 15. Various molecular mechanisms are known to lead to PWS: deletion 15q11-q13 (75% of cases), maternal uniparental disomy (matUPD15) (23%) and imprinting defects (2%). FISH and microsatellite analysis are required to ... more

Cebus apella; DNA polymorphisms; Microsatellites; Population structure; Short tandem repeats; Tufted capuchins

There have been numerous studies genetically characterizing Old World Primates using microsatellites. However, few studies have been made of New World species and none on free-ranging Cebus apella, even though it is probably the most widely distributed species of monkey in the New World. The paucity of studies is due, in part, to the lack of polymorphisms described for this species. We ... more

Arapaima gigas; conservation genetics; Lower Amazon; Microsatellites; Multiplex polymerase chain reaction; pirarucu

The aim of the present study was the development of a multiplex genotyping panel of eight microsatellite markers of Arapaima gigas, previously described. Specific primer pairs were developed, each one of them marked with either FAM-6, HEX or NED. The amplification conditions using the new primers were standardized for a single reaction. The results obtained demonstrate high heterozygosity ( ... more

Frogs; Microsatellites; Physalaemus; Population structure; Related species

Various species of the Physalaemus cuvieri group of frogs are difficult to distinguish morphologically, making molecular analysis an attractive alternative for indentifying members of this group, which is considered to be at risk because of loss of habitat. The genetic structure of natural populations of P. ephippifer and P. albonotatus species was investigated ... more
