Pinus krempfii Lecomte (Pinaceae) is an endemic tree to Vietnam with restricted habitats at higher altitudes in the highlands. In this study, genetic variation of four populations of P. krempfii was assessed using 17 microsatellite markers (single sequence repeats). Of these 17 markers, eight were polymorphic, and among the 42 putative alleles amplified, .. Read More»

The climatic fluctuations of the Quaternary have influenced the distribution of numerous plant and animal species. Several species suffer population reduction and fragmentation, becoming restricted to refugia during glacial periods and expanding again during interglacials. The reduction in population size may reduce the effect.. Read More»

Among the diseases affecting banana (Musa sp), yellow Sigatoka, caused by the fungal pathogen Mycosphaerella musicola Leach, is considered one of the most important in Brazil, causing losses throughout the year. Understanding the genetic structure of pathogen populations will provide insight into the life history of pathogens, including the evolutionary p.. Read More»

To study the levels of genetic diversity, and population structure, of Houttuynia cordata Thunb, the genetic background and relationships of populations were analyzed in terms of environmental factors. The genetic diversity and population structure of H. cordata were investigated using sequence-related amplified polymorphisms and correlation with environm.. Read More»

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. a.. Read More»

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,.. Read More»

Fenneropenaeus penicillatus is a widely distributed economically and ecologically important shrimp species, which is endangered in China. Sequence analysis of 16s rRNA and control region (CR) fragments from mitochondrial DNA was conducted to obtain information on genetic diversity and population structure. Individuals from 12 ..

We isolated and characterized 14 polymorphic microsatellite loci in the Japanese anchovy (Engraulis japonicus) using a (GT)13-enriched genomic library. The numbers of alleles per locus ranged from 6 to 31, with a mean of 17.8. The observed and expected heterozygosities ranged from 0.180 to 0.949 and from 0.172 to 0.966, with means of 0.731 and 0.825, resp.. Read More»

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... Read More»

Eucommia ulmoides Oliver, a single extant species of Eucommiaceae, is an endemic dioecious tree in China. The natural resources of E. ulmoides have rapidly declined in recent years because of the over-collection of its cortex. To design a suitable protection strategy, it is necessary to develop a set of molecular markers to in.. Read More»
