Short tandem repeat (STR) variation has been proposed as a major explanatory factor in the heritability of complex traits in humans and model organisms. However, we still struggle to incorporate STR variation into genotype-phenotype maps. We review here the promise of STRs in contributing to complex trait heritability and highlight the challenges that STRs pose due to their repetitive nature. W...

the hla class ii genes of human major histocompatibility complex (mhc) exhibit an extensive degree of genetic polymorphism. this region subdivides into four sub-regions dp, do, dq, and dr. there are five different dr haplotypes that all contain a highly polymorphic allele called hla-drb1. in most recent studies, the association between hla-drb1 and a large number of diseases such as multiple sc...

Hematopoietic stem cell transplantation is the curative option for patients with myelodysplastic syndrome; however, it requires a long post-transplantation follow-up. A 53-year-old woman with a diagnosis of myelodysplastic syndrome underwent related donor allogeneic hematopoietic stem cell transplantation in July 2006. Three months after transplantation, a comparative short tandem repeat analys...

Morphology-based taxonomy via exiguously reproductive organ has severely limitation on bamboo taxonomy, mainly owing to infrequent and unpredictable flowering events of bamboo. Here, we present the first genome-wide analysis and application of microsatellites based on the genome of moso bamboo (Phyllostachys edulis) to assist bamboo taxonomy. Of identified 127,593 microsatellite repeat-motifs, ...

In order to identify new markers around the glaucoma locus GLC1B as a tool to refine its critical region at 2p11.2-2q11.2, we searched the critical region sequence obtained from the UCSC database for tetranucleotide (GATA)n and (GTCT)n repeats of at least 10 units in length. Three out of four potential microsatellite loci were found to be polymorphic, heterozygosity ranging from 64.56% to 79.59...

Infection with Neospora caninum is regarded as a significant cause of abortion in cattle. Despite the economic impact of this infection, relatively little is known about the biology of this parasite. In this study, mini and microsatellite DNAs were detected in the genome of N. caninum and eight loci were identified that each contained repetitive DNA which was polymorphic among different isolate...

A set of 13 simple sequence repeat markers was developed from D. trimaculatus genomic DNA, tested for D. auripinnis and characterized using 40 individuals per species. All the loci were polymorphic with a number of alleles ranging from three to 30. Observed heterozygosities varied from 0.23 to 0.89 for D. trimaculatus and from 0.11 to 0.85 for D. auripinnis. Early results show that these will b...

A set of 46 grapevine denominations was genotyped at 11 microsatellite loci in order to discriminate them. Ninety four alleles with a mean number of 8.55 alleles per locus were observed in a total of 37 detected unique genotypes. Previously assumed synonyms were confirmed and several cases of homonymy resolved. Comparison of the data obtained in this study with data of 32 genotypes previously r...

We investigated how queens share parentage (skew) in the Argentine ant, Linepithema humile, a social insect with multiple queens (polygyny). Overall, maternity of 546 male and female sexuals that mated successfully was determined with microsatellites in 26 colonies consisting of two queens and workers. The first main finding was that queens all contributed to sexual production. However, there w...

Hitch-hiking to a site under balancing selection is expected to produce a local increase in nucleotide polymorphism and a decrease in population differentiation compared with the background genomic level, but empirical evidence supporting these predictions is scarce. We surveyed molecular diversity at four genes flanking the region controlling self-incompatibility (the S-locus) in samples from ...
