We show the presence of numerous short tandem repeats in the human cytomegalovirus (HCMV) genome and assess their usefulness as molecular markers. The genome is shown to contain at least 24 microsatellite regions that exhibit length polymorphisms. Insertion-deletion polymorphisms at these short tandem repeats are common (80% of repeats examined are polymorphic among two laboratory strains and 1...

We screened 42 sporadic gastric tumors and found that seven of them had significant microsatellite instability. These were then studied at 26 microsatellite loci, comprising di-, tri- and tetranucleotide repeats. The instability level of individual microsatellites in the tumors was found to be positively correlated with the population average heterozygosity and variance of repeat number of the ...

Microsatellite loci were screened from the genomic data of Dysomma anguillare and their composition distribution analysed by bioinformatics for first time. The results showed that 4,060,742 scaffolds with a total length 1,562 Mb obtained high-throughput sequencing 1,160,104 microsatellite MISA screening, which distributed on 770,294 scaffolds. occurrence frequency relative abundance 28.57% 743/...

the kermani sheep is an important meat producing an animal in iran and its economic efficiency is mainly dependent on its growth and reproduction ability. inter-simple sequence repeat (issr) is the genome region between microsatellite loci. the aim of this study was to evaluate the association of two different issr markers with predicted breeding values (pbv) of body weight trait in kermani she...

Microsatellites, also known as simple sequence repeats (SSRs) or short tandem repeats (STRs), have extensively been exploited as molecular markers for diverse applications. Recently, their role in gene regulation and genome evolution has also been discussed widely. We have developed UgMicroSatdb (Unigene MicroSatellite database), a web-based relational database of microsatellites present in uni...

A large insert genomic library from eastern white pine (Pinus strobus) was probed for the microsatellite motifs (AC)n and (AG)n, all 10 trinucleotide motifs, and 22 of the 33 possible tetranucleotide motifs. For comparison with a species from a different subgenus, a loblolly pine (Pinus taeda) genomic library was also probed with the same set of di- and tri-nucleotide repeats and 11 of the tetr...

Microsatellites are abundant in eukaryotic genomes and have high rates of strand slippage-induced repeat number alterations. They are popular genetic markers, and their mutations are associated with numerous neurological diseases. However, the minimal number of repeats required to constitute a microsatellite has been debated, and a definition of a microsatellite that considers its mutational be...

In order to characterize triand tetranucleotide microsatellites in the black tiger prawn, Penaeus monodon, a genomic library of P. monodon was screened with the repeats (GAA)n, (GATA)n, (GGAT)n, (GGAA)n and (CACC)n. In the 79 positive clones isolated, the repeats (GATA)n was found at the highest frequency, followed by the (GAA)n while the other sequence types were rare or not found. Sequencing ...

Microsatellites, also known as simple sequence repeats (SSRs), are among the most commonly used marker types in evolutionary and ecological studies. Next Generation Sequencing techniques such as 454 pyrosequencing allow the rapid development of microsatellite markers in nonmodel organisms. 454 pyrosequencing is a straightforward approach to develop a high number of microsatellite markers. There...

The prevalence of obesity and diabetes changes dramatically with lifestyle and unequal risk among individuals have made scientists interested to understand how the environment interferes with genetic factors to make it so-called genetic predisposition. This study aimed to explore wherethe most variable region is in leptin gene and analyse  microsatellite repeats with direct sequencing in Iraqis...
