Genetic diversity in Tunisian populations of faba bean (Vicia faba L.) based on morphological traits and molecular markers

Authors: I.Z. Backouchi, M. Aouida, N. Khemiri and M. Jebara

Genetic diversity within Vicia faba L. is key to the genetic improvement of this important species. In this study, morphological traits and RAPD molecular markers were used to assess the levels of polymorphism across 12 Tunisian populations, three major and nine minor from different locations. Analysis of morphological traits indicated that the three majo.. Read More»

Identification of 15 novel polymorphic microsatellite loci in pearl oyster (Pinctada fucata)

Authors: S.G. Fan, J.X. Wang, D.L. Zhang, Y.H. Guo and D.H. Yu

The pearl oyster Pinctada fucata is a commercially important marine shellfish. As a result, genetic improvement and selective-breeding program have been conducted for this species. Polymorphic microsatellites are effective molecular markers to investigate molecular marker-assisted selection and genetic variance. In this study,.. Read More»

Genetic diversity in wild (Sus scrofa scrofa) and domestic (Sus scrofa domestica) pigs and their hybrids based on polymorphism of a fragment of the D-loop region in the mitochondrial DNA

Authors: S.F. Grossi, J.F. Lui, J.E. Garcia and F.V. Meirelles

We examined the variation in mitochondrial DNA by sequencing the D-loop region in wild and domestic (large-white breed) pigs, in hybrids between domestic and wild pigs, and in Monteiro pigs. A D-loop fragment of approximately 330 bp was amplified by PCR. Sequencing of DNA amplicons identified haplotypes previously described as.. Read More»

Development of novel chloroplast microsatellite markers for Ginkgo biloba

Authors: M. Xu, L.A. Xu, F.L. Cao, H.J. Zhang and F.X. Yu

Ginkgo biloba is considered to be a living fossil that can be used to understand the ancient evolutionary history of gymnosperms, but little attention has been given to the study of its population genetics, molecular phylogeography, and genetic resources assessment. Chloroplast simple sequence repeat (cpSSR) markers are powerful tools for genetic studies .. Read More»

Genetic diversity of the endemic flat-needle pine Pinus krempfii (Pinaceae) from Vietnam revealed by SSR markers

Authors: D.T. Phong, T.T. Lieu, V.T.T. Hien and N.T. Hiep

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»

Analysis of transferability of microsatellite primers (SSR) in wild Passiflora species and intraspecific genetic diversity in Passiflora alata

Authors: M.A.A. Silva, M.M. Souza, G.S. Silva, C.A.F. Melo, R.X. Corr�ªa, I.S. Ara�ºjo and L.D.H.C.S. Concei�§�£o

The genus Passiflora L. is the most representative of Passifloraceae, with over 500 known species, among which 150-200 originated from Brazil. In addition to the great commercial importance of this genus for the fruit market, many of the species have exotic flowers with a huge diversity of colors and can thereby be ex.. Read More»

Genetic diversity and population structure in Harpadon nehereus based on sequence-related amplified polymorphism markers

Authors: Z.H. Zhu, H.Y. Li*, Y. Qin and R.X. Wang

In this study, the genetic diversity among ten populations of the Bombay duck was studied on the basis of sequence-related amplified polymorphism (SRAP). The ten populations were collected from the East China Sea and South China Sea areas. A total of 98 loci were obtained from 292 individuals using eight SRAP primers. The aver.. Read More»
