Amplified fragment length polymorphism (AFLP) markers were used to investigate the genetic variation in a sample of seven goat (Capra hircus) populations. A total of 210 individuals (30 per population) were analysed using seven selected AFLP primer combinations that produced 219 clear polymorphisms. Four autochthonous goat breeds (Bionda dell'Adamello,(More)
The present study was designed to address the physiological role played by cAMP on gap junction (GJ) mediated communications between oocyte and cumulus cells during in vitro maturation. Cyclic AMP was stimulated by different collection and maturation media known to induce different rates of nuclear maturation and developmental competence as well as(More)
The effectiveness of single nucleotide polymorphisms (SNPs) for the assignment of cattle to their source breeds was investigated by analysing a panel of 90 SNPs assayed on 24 European breeds. Breed assignment was performed by comparing the Bayesian and frequentist methods implemented in the STRUCTURE 2.2 and GENECLASS 2 software programs. The use of SNPs(More)
Two pig cell lines derived from kidney and trachea tissues and referred to as newborn swine kidney (NSK) and newborn pig trachea (NPTr) were established following serial culture of primary cells. They were characterized by an epithelial-like morphology, high capacity to replicate and stability of the cell monolayer for several days after seeding. Their(More)
We have tested amplified fragment length polymorphism (AFLP) technology, in comparison with isoenzyme analysis, for the simultaneous detection of inter- and intraspecific cell line cross-contaminations (CCCs) in the cell line collection held at the Istituto Zooprofilattico della Lombardia e dell'Emilia Romagna. Isoenzyme analysis identified four cases of(More)
The Neolithic introduction of domestic cattle into Europe was followed by differential adaptation, selection, migration and genetic isolation, leading ultimately to the emergence of specialized breeds. We have studied the differentiation of European cattle by amplified fragment length polymorphism (AFLP) fingerprinting. Combining AFLP data sets from two(More)
The Etruscan culture developed in Central Italy (Etruria) in the first millennium BC and for centuries dominated part of the Italian Peninsula, including Rome. The history of the Etruscans is at the roots of Mediterranean culture and civilization, but their origin is still debated: local or Eastern provenance? To shed light on this mystery, bovine and human(More)
The verification of the breed origin of animal products is relevant for food safety and authenticity. We assessed the suitability of AFLP molecular markers in the assignment of cattle individuals to their breed of origin. Three hundred and ninety-six animals belonging to 16 cattle breeds genotyped with 141 AFLP markers were used as reference data set.(More)
The aim of this study was to assess the genetic diversity of four autochthonous cattle breeds of Tuscany and their relationships in comparison with Italian Friesian and Italian Brown, using amplified fragment length polymorphism markers. A total of 212 individuals were genotyped with three primer combinations generating 102 polymorphic markers. Average(More)
BACKGROUND Several approaches can be used to determine the order of loci on chromosomes and hence develop maps of the genome. However, all mapping approaches are prone to errors either arising from technical deficiencies or lack of statistical support to distinguish between alternative orders of loci. The accuracy of the genome maps could be improved, in(More)
