Thirty polymorphic microsatellite markers were developed for the Atlantic surfclam, Spisula solidissima, from an enriched library and characterized in 24 clams from a wild population. The number of alleles ranged from 3 to 16 per locus. The expected and observed heterozygosities ranged from 0.1942 to 0.9238 and 0.0833 to 0.875 respectively. Six loci showed significant (P < 0.05 after Bonferroni...
The microsatellite hybrid capture technique was designed to enrich simultaneously for various microsatellite repeats from a genomic clone. It is illustrated in this report that different repeat motifs, including polymorphic ones, can be efficiently isolated in a single experiment. In principle, this technique can be applied to any type of genomic clones to facilitate the isolation of informativ...
UNLABELLED PREMISE OF THE STUDY Ten microsatellite markers were developed and characterized in a gynodioecious summer-deciduous shrub, Daphne jezoensis, to facilitate studies of the evolution of gynodioecy in the species. • METHODS AND RESULTS We used a next-generation sequencing approach with the Ion Personal Genome Machine (PGM) system to identify and develop microsatellite markers with ...
A unique community of four syntopic eagle species exists in north-central Kazakhstan. Questions about behaviour and genetics in these four species would benefit from the development of microsatellite markers. We isolated eight polymorphic microsatellite repeats (AAAG) n from the eastern imperial eagle ( Aquila heliaca ) genome using a hybridization enrichment technique. These loci revealed mode...
Genome-wide analysis of microsatellite polymorphism in chicken circumventing the ascertainment bias.
Studies of microsatellites evolution based on marker data almost inherently suffer from an ascertainment bias because there is selection for the most mutable and polymorphic loci during marker development. To circumvent this bias we took advantage of whole-genome shotgun sequence data from three unrelated chicken individuals that, when aligned to the genome reference sequence, give sequence inf...
Microsatellite markers (also known as SSRs, Simple Sequence Repeats) are widely used in plant science and are among the most informative molecular markers for population genetic investigations, but the development of such markers presents substantial challenges. In this report, we discuss how next generation sequencing can replace the cloning, Sanger sequencing, identification of polymorphic lo...
Tarim schizothoracin (Schizothorax biddulphi) is an endemic fish species native to the Tarim River system of Xinjiang and has been classified as an extremely endangered freshwater fish species in China. Here, we used a next generation sequencing platform (ion torrent PGM™) to obtain a large number of microsatellites for S. biddulphi, for the first time. A total of 40577 contigs were asse...
Fourteen new microsatellite loci were developed and tested on Atlantic herring Clupea harengus with 39 individuals from Iceland and 49 individuals from Norway. The microsatellites, which contain di, tri and tetranucleotide repeats, are polymorphic (7-30 alleles), with observed heterozygosity ranging between 0·69 and 1·00 and expected heterozygosity between 0·55 and 0·97.
We describe and test a Markov chain model of microsatellite evolution that can explain the different distributions of microsatellite lengths across different organisms and repeat motifs. Two key features of this model are the dependence of mutation rates on microsatellite length and a mutation process that includes both strand slippage and point mutation events. We compute the stationary distri...
