A consensus microsatellite-based linkage map of the turbot (Scophthalmus maximus) was constructed from two unrelated families. The mapping panel was derived from a gynogenetic family of 96 haploid embryos and a biparental diploid family of 85 full-sib progeny with known linkage phase. A total of 242 microsatellites were mapped in 26 linkage groups, six(More)
A genetic analysis of freshwater pearl mussel Margaritifera margaritifera populations from NW Spain, a peripheral area of its European distribution, was carried out using microsatellite markers. These populations were formerly reported as genetically differentiated on the basis of growth and longevity studies. Ten loci previously characterized in(More)
An analysis of Robertsonian polymorphism and variation in the number of active NORs has been carried out in several populations of brown trout (Salmo trutta) from Northwestern Spain. The karyotype of this species appears to be soundly established, and essentially no variation has been found in chromosome number. Interindividual and interpopulation variation(More)
Previous studies using mitochondrial markers and microsatellites revealed a new highly differentiated Atlantic lineage of brown trout in the Iberian Peninsula mainly confined to the Upper Duero Basin. Data suggest that Duero lineage (DU) hybridizes with previously described Atlantic (AT) lineages in that basin. However, nuclear and cytogenetic data suggest(More)
Gynogenesis was assessed by different methods in 2 families of gynogenetic offspring in turbot (Scophthalmus maximus). Karyotype analysis in embryos and larvae demonstrated high accuracy in estimation of ploidy level, but performance was uneven given the low quality and number of plates obtained. The use of silver staining to estimate the number of nucleoli(More)
The 5S multigene family consists of a highly conserved coding sequence of 120 bp forming arrays of hundreds to thousands of tandem copies, separated by variable non-transcribed spacers (NTS). These 5S genes are clustered in a single locus or in multiple loci [1]. There are few reports on the location of 5S rDNA in ¢sh chromosomes [2,3]. Salmo trutta (brown(More)
Allergy is on the rise worldwide. Asthma, food allergy, dermatitis, and systemic anaphylaxis are amongst the most common allergic diseases. The association between allergy and altered behavior patterns has long been recognized. The molecular and cellular pathways in the bidirectional interactions of nervous and immune systems are now starting to be(More)
The aim of this study was to analyze the morphological variation of brown trout (Salmo trutta) in the Duero basin, an Atlantic river basin in the Iberian Peninsula, where a spatial segregation of two divergent lineages was previously reported, based on isozyme, microsatellite and mtDNA data. In these studies, two divergent pure regions (Pisuerga and(More)
