چکیده

We describe the sequences of six primer pairs for the PCR amplification of nuclear microsatellite markers in the tree shrews, Tupaia glis and T. belangeri. Multilocus genotyping based on non-destructive DNA sampling of live-trapped animals reveals high allelic variability (A) and heterozygosity (He) at these loci. Such characteristics make these genetic markers ideal for linkage mapping and comparative genomics, and for studies of pedigree relationships, population structure, and population genetic variability in wild populations. We illustrate another use of these markers in the study of genetic erosion in small recently fragmented natural populations of tree shrews in south Thailand. This method for detecting and monitoring genetic erosion in fragmented populations can be applied to larger taxa of traditional concern to wildlife managers.

Characterization of 12 polymorphic microsatellite markers in the Chinese tree shrew (Tupaia belangeri chinensis).

The Chinese tree shrew (Tupaia belangeri chinensis) is a small experimental animal with a close affinity to primates. This species has long been proposed to be an alternative experimental animal to primates in biomedical research. Despite decades of study, there is no pure breed for this animal, and the overall genetic diversity of wild tree shrews remains largely unknown. In order to obtain a ...

Use of microsatellite markers for molecular characterization of cumin (Cuminum cyminum L.) ecotypes

In this study, Simple Sequence Repeat markers (SSR) were used to investigate the genetic variation between 49 cumin ecotypes collected from 9 different provinces of Iran. SSR primers Elap1479, Elap040 and Elap1493 showed the highest (89%), while Elap1340 and Elap017 showed the lowest (56%) number of polymorphic bands. Polymorphism information content (PIC) values varied between 0.18 - 0.37. The...

A Review of Microsatellite Marker Usage in the Assessment of Genetic Diversity of Camelus

Camels have been regarded as the desert ship and they play multi-utility role in the world. Estimation of genetic parameters is foremost step towards managing the genetic resources for their conservation and sustainable utilization. Microsatellite markers have been extensively used in cattle, sheep, goat and camels. However, genetic characterization studies on camels has been poorly recorded. T...

Microsatellite Isolation and Characterization in Pomegranate (Punica granatum L.)

Development of microsatellite markers has been an increasing trend in crop genetic studies because oftheir applicability in breeding programs. Here we report the development of inter simple sequencerepeat (SSRs) in pomegranate (Punica granatum L.) using an enrichment method that makes use of magneticbeads. Enriched genomic libraries with AG and ATG microsatellite motifs were c...

Genetic variation of Garra rufa fish in Kermanshah and Bushehr provinces, Iran, using SSR microsatellite markers

Six highly variable microsatellite loci were used to investigate the genetic diversity and population structure of the Garra rufa in Kermanshah and Bushehr provinces, Iran. All of the 6 microsatellite loci screened in this study showed polymorphism. A total of 90 individual fish from 3 populations were genotyped and 60 alleles were observed in all loci. The number of alleles per locus ranged fr...
