Wheat fulfills 20% of global caloric requirement. World needs 60% more wheat for 9 billion population by 2050 but climate change with increasing temperature is projected to affect wheat productivity adversely. Trait improvement and management of wheat germplasm requires genomic resource. Simple Sequence Repeats (SSRs) being highly polymorphic and ubiquitously distributed in the genome, can be a...

Microsatellites or Single Sequence Repeats (SSRs) are extensively employed in plant genetics studies, using both low and high throughput genotyping approaches. Motivated by the importance of these sequences over the last decades this review aims to address some theoretical aspects of SSRs, including definition, characterization and biological function. The methodologies for the development of S...

The potential of different DNA based molecular markers was examined for the detection of single nucleotide polymorphism (SNP) in the waxy gene and a microsatellite (SSR) sequence closely linked to it in a collection of rice varieties. DNA was extracted from leaf samples of 68 different rice cultivars by the CTAB method and specific primers were designed for the amplification of waxy gene and SS...

Microsatellite (simple sequence repeats, SSRs) marker is one of the most widely used markers in marker-assisted breeding. As one type of functional markers, MicroRNA-based SSR (miRNA-SSR) markers have been exploited mainly in animals, but the development and characterization of miRNA-SSR markers in plants are still limited. In the present study, miRNA-SSR markers for Medicago truncatula (M. tru...

Among different classes of molecular markers, expressed sequence tags (ESTs) are a new resource for developing simple sequence repeat (SSR) functional markers for genotyping and genetic mapping in F1 hybrid populations of Vitis vinifera L. Recently, because of the availability of an enormous amount of data for ESTs in the public domain, the emphasis has shifted from genomic SSRs to EST-SSRs, wh...

Short Sequence Repeat (SSR) typing of Mycobacterium avium subspecies paratuberculosis (Map) isolates is one of the most commonly used method for genotyping this pathogen. Currently used techniques have challenges in analyzing mononucleotide repeats >15 bp, which include some of the Map SSRs. Fragment analysis is a relatively simple technique, which can accurately measure the size of DNA fragmen...

Among commonly applied molecular markers, simple sequence repeats (SSRs, or microsatellites) possess advantages such as a high level of polymorphism and codominant pattern of inheritance at individual loci. To facilitate systematic and rapid genetic mapping in soybean, we designed a genotyping panel comprised 304 SSR markers selected for allelic diversity and chromosomal location so as to provi...

Hydrangea (Hydrangea macrophylla) is an important ornamental crop that has been cultivated for more than 300 years. Despite the economic importance, genetic studies hydrangea have limited by lack of resources. Genetic linkage maps and subsequent trait mapping are essential tools to identify make markers available marker-assisted breeding. A transcriptomic study was performed on two cultivars, V...

This paper reports the development of the first SSR marker-based sugarcane (Saccharum spp.) molecular identity database in the world. Since 2005, 1,025 sugarcane clones were genotyped, including 811 Louisiana, 45 Florida, 39 Texas, 130 foreign, and eight consultant/seed company clones. Genotyping was done on a fluorescence-capillary electrophoresis detection platform involving 21 highly polymor...

A set of 16 expressed sequence tag (EST)-derived simple sequence repeat (SSR) and 15 EST-derived single nucleotide polymorphism (SNP) markers together with 4 amplified fragment length polymorphism (AFLP) primer combinations were analyzed on 43 wild (Hordeum vulgare ssp. spontaneum – HS), 35 cultivated (H. vulgare ssp. vulgare – HV) and 12 elite (H. vulgare ssp. vulgare – from EU) barley lines. ...
