A set of 52 (CT)n and 23 (GT)n microsatellites in honeybee, 24 (CT)n and 2 (GT)n microsatellites in bumble-bee (n > 6) have been isolated from partial genomic libraries and sequenced. On average, (CT)n and (GT)n microsatellites occur every 15 kb and 34 kb in honeybee and every 40 kb and 500 kb in bumble-bee, respectively. The prevailing categories are imperfect repeats for (CT)n microsatellites...
We have screened the nearly complete DNA sequence of the human Y chromosome for microsatellites (short tandem repeats) that meet the criteria of having a repeat-unit size of > or = 3 and a repeat count of > or = 8 and thus are likely to be easy to genotype accurately and to be polymorphic. Candidate loci were tested in silico for novelty and for probable Y specificity, and then they were tested...
Genome-Wide Mining, Characterization, and Development of Microsatellite Markers in Gossypium Species
Although much research has been conducted to characterize microsatellites and develop markers, the distribution of microsatellites remains ambiguous and the use of microsatellite markers in genomic studies and marker-assisted selection is limited. To identify microsatellites for cotton research, we mined 100,290, 83,160, and 56,937 microsatellites with frequencies of 41.2, 49.1, and 74.8 micros...
Polymerase chain reaction primer pairs for a total of 25 nuclear-encoded microsatellites (loci) were developed from genomic DNA libraries of lane snapper ( Lutjanus synagris ), mutton snapper ( Lutjanus analis ), and yellowtail snapper ( Ocyurus chrysurus ). The microsatellites include 24 perfect (21 dinucleotide and three trinucleotide) and one imperfect (combination tetranucleotide/tetranucle...
The construction of high-density linkage maps for use in identifying loci underlying important traits requires the development of large numbers of polymorphic genetic markers spanning the entire genome at regularly spaced intervals. As part of our efforts to develop markers for rainbow trout (Oncorhynchus mykiss), we performed a comparison of allelic variation between microsatellite markers dev...
Single nucleotide polymorphisms (SNPs) are appealing genetic markers due to several beneficial attributes, but uncertainty remains about how many of these bi-allelic markers are necessary to have sufficient power to differentiate populations, a task now generally accomplished with highly polymorphic microsatellite markers. In this study, we tested the utility of 37 SNPs and 13 microsatellites f...
UNLABELLED PREMISE OF THE STUDY Tuber aestivum, the most common truffle in Europe, plays an important role in the commercial truffle market. For the first time, microsatellite primers were developed to investigate polymorphism within this species. • METHODS AND RESULTS Using direct shotgun pyrosequencing, 15 polymorphic microsatellites were identified out of the 7784 perfect microsatellite...
AIMS To develop an assay which would determine the parentage of hydatidiform molar pregnancies. METHODS DNA was extracted from formalin fixed, paraffin wax embedded tissue from hydatidiform molar pregnancies and spontaneous abortions after separation of chorionic villi and decidua. PCR amplification of dinucleotide repeat sequences ("microsatellites") was performed using three different prime...
Microsatellite DNA markers isolated from wild species khinjuk (Pistacia khinjuk Stocks.) were used to evaluate the genetic diversity available in Iranian pistachio cultivars. Out of the 27 SSR primers tested initially, 25 could amplify the DNA in different pistachio cultivars, of which 19 primer pairs produced clear bands. Based on the amplification profiles of the genotypes by the remaining pr...
Thirteen nuclear-encoded microsatellites from a genomic DNA library of Serra Spanish mackerel, Scomberomorus brasiliensis, were isolated and characterized. The microsatellites include 10 perfect repeats (eight tetranucleotide and two dinucleotide) and three imperfect repeats (two tetranucleotide and one dinucleotide). An additional five microsatellites, isolated originally from two congeneric s...
