First identification of polymorphic microsatellite markers in the Burgundy truffle, Tuber aestivum (Tuberaceae)

2014

SPEIPMCT2Pour cette revue, la version de l'éditeur est autorisée mais il y a un embargo d'un an (mentionné dans les Conditions générales : "On Institutional Repositories after 12 months").On peut donc mettre la PJ en "publique" mais il faut indiquer une date d'embargo (un an à partir de la date de publication). L'embargo sera levé automatiquement. Laissée lors du dépôt en workflow par prudence.; Premise of the study: Tuber aestivum, the most common truffle in Europe, plays an important role in the commercial truffle market. For the first time, microsatellite primers were developed to investigate polymorphism within this species. • Methods and Results: Using direct shotgun pyrosequencing, 15…

Genetic and aromatic diversity of the Burgundy truffle

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…

Genetic diversity of Tuber aestivum / uncinatum

2012

SPE IPM CT2 (vu VM)SPEIPMCT2 (vu VM); Tuber aestivum and Tuber uncinatum share a complicated common history from a taxonomic point of view. Indeed, different previous studies have shown contradictory conclusions. For some authors, Tuber aestivum and Tuber uncinatum are a single species and for others, they are two different species. In another study, we used 9 molecular markers: ITS1, ITS2, nuSSU, nuLSU, mtLSU, mtSSU, EF1α, β-tubulin and RPB2. The results show some genetic differences between samples for some of the analyzed sequences. However, no genetic differentiation that would support the separation of two different species was observed. We have concluded that Tuber aestivum and Tuber …
