We reported 31 microsatellite markers that have been developed from microsatellite-enriched and direct shotgun pyrosequencing libraries of Plasmopara viticola, the causal agent of grapevine downy mildew. These markers were optimized for population genetics applications and used to characterize 96 P. viticola isolates from three European and three North American populations.
We used 320 young-of-the-year (YOY) specimens of the highly migratory and overfished Atlantic bluefin tuna, Thunnus thynnus, Linnaeus 1758, to evaluate the hypothesis that Atlantic bluefin tuna comprises 2 stocks with spawning grounds in the Gulf of Mexico and in the Mediterranean Sea. Significant genetic differentiation at 8 nuclear microsatellite loci (F(ST) = 0.0059, P = 0.0005) and at the m...
We report the development of 18 new polymorphic microsatellite DNA markers derived from Crassostrea gigas expressed sequences tags. Genotyping of 48 wild adult oysters sampled from Marennes-Oléron bay (France) revealed 12 to 48 alleles per locus. Observed and expected heterozygosity levels ranged from 0.64 to 1 and from 0.77 to 0.97, respectively. The development of these new markers creates a ...
The fitness consequences of heterozygosity and the mechanisms underpinning them are still highly controversial. Using capture-mark-recapture models, we investigated the effects of individual heterozygosity, measured at 16 microsatellite markers, on age-dependent survival and access to dominance in a socially monogamous mammalian species, the alpine marmot. We found a positive correlation betwee...
For several years Y-chromosomal microsatellites (short tandem repeats, STRs) have been well established in forensic practice. In this context, the genetic characteristics of the Y chromosome (i.e. its paternal inheritance and lack of recombination) render STRs particularly powerful. However, genetic differences between male populations appear to be larger for Y-STRs than for autosomal STRs, a f...
The performance of a multiplex assay with 52 autosomal single nucleotide polymorphisms (SNPs) developed for human identification was tested on 124 mother-child-father trios. The typical paternity indices (PIs) were 10(5)-10(6) for the trios and 10(3)-10(4) for the child-father duos. Using the SNP profiles from the randomly selected trios and 700 previously typed individuals, a total of 83,096 c...
When populations or species have recently separated they often share genetic variation. However, it can be difficult to determine whether shared polymorphisms are the result of gene flow, the result of the persistence of variation in both populations since the time of common ancestry, or both of these factors. We have developed an empirical protocol for using loci that include unique nuclear DN...
Combining genotypes across datasets is central in facilitating advances in genetics. Data aggregation efforts often face the challenge of record matching-the identification of dataset entries that represent the same individual. We show that records can be matched across genotype datasets that have no shared markers based on linkage disequilibrium between loci appearing in different datasets. Us...
