Genetic diversity and population structure of Sicilian sheep breeds using microsatellite markers
2012
Abstract Genetic diversity studies in domestic animals aim at evaluating genetic variation within and across breeds mainly for conservation purposes. In Sicily, dairy sheep production represents an important resource for hilly and mountain areas economy. Their milk is used for the production of traditional raw milk cheeses, sometimes protected designation of origin (PDO) cheeses. In some cases, the quality of these products is linked to a specific breed, i.e. mono-breed labelled cheeses and it is therefore important to be able to distinguish the milk of a breed from that of others, in order to guarantee both the consumer and the breed itself. In order to investigate the genetic structure an…
Diversité génétique et aromatique de la truffe de Bourgogne
2013
Truffles are ectomycorrhizal Ascomycota fungi belonging to the Tuberaceae family and more specifically to the Tuber genus. More than thirty Tuber species are currently described in Europe. In this thesis, we specifically focused on the Tuber aestivum-uncinatum model. This truffle is commonly called "Burgundy Truffle" and has a gastronomic and cultural interest.The first part of this thesis focused on the taxonomic status of the Burgundy truffle (Tuber uncinatum). For this, we used a multi-marker approach combining several genetic markers commonly used at the interspecific scale. Our analyses showed that the two taxa, Tuber aestivum (summer truffle) and Tuber uncinatum are conspecific.In the…
Population genetics on Ambrosia genus: past, present and future
2014
National audience; A new Task Force within the COST-SMARTER has recently been created. This group is composed of population genetics experts from five European countries in charge of focusing on “Genetics on Ambrosia” (Austria, France, Germany, Hungary, Sweden). Their mission was to review molecular methods used in published genetics studies on common ragweed and to discuss about future projects. Two different types of molecular markers are generally used in the literature to investigate the genetic structure within and between introduced and/or native populations of common ragweed: microsatellite markers and amplified fragment length polymorphism (AFLP). These methods permit the researcher…
