Frequency of the two mating types in the soil under productive and non-productive trees in five French orchards of the Périgord black truffle (Tuber melanosporum Vittad.)
The Périgord black truffle (Tuber melanosporum Vittad.) is an ectomycorrhizal fungus forming edible fructifications. The production of T. melanosporum relies mainly on man-made plantations. T. melanosporum is a h...

Open AccessSoil temperature and hydric potential influences the monthly variations of soil Tuber aestivum DNA in a highly productive orchard
Tuber aestivum, also known as the summer or Burgundy truffle, is an ectomycorrhizal Ascomycete associated with numerous trees and shrubs. Its life cycle occurs in the soil, and thus soil parameters such as temper...

New insights into black truffle biology: discovery of the potential connecting structure between a Tuber aestivum ascocarp and its host root
According to isotopic labeling experiments, most of the carbon used by truffle (Tuber sp.) fruiting bodies to develop underground is provided by host trees, suggesting that trees and truffles are physically conne...

Influence of annual climatic variations, climate changes, and sociological factors on the production of the Périgord black truffle (Tuber melanosporum Vittad.) from 1903–1904 to 1988–1989 in the Vaucluse (France)
From 1903–1904 to 1988–1989, the two World Wars and sociological factors as rural desertification and changes in land uses mainly explained the decline of black truffle production in the Vaucluse department, w...

Temporal changes of bacterial communities in the Tuber melanosporum ectomycorrhizosphere during ascocarp development
Ectomycorrhizae create a multitrophic ecosystem formed by the association between tree roots, mycelium of the ectomycorrhizal fungus, and a complex microbiome. Despite their importance in the host tree’s physi...

Certainties and uncertainties about the life cycle of the Périgord black truffle (Tuber melanosporum Vittad.)
Several aspects of the life cycle of the Périgord black truffle have been elucidated only recently, while others remain either controversial or unstudied. In this paper, we present a revised li...

The Black Truffles Tuber melanosporum and Tuber indicum
The European species Tuber melanosporum and the Asian species T. indicum are phylogenetically and morphologically very close. T. indicum is formed by a complex of cryptic species or ecotypes spread from India to ...

Study of nitrogen and carbon transfer from soil organic matter to Tuber melanosporum mycorrhizas and ascocarps using 15N and 13C soil labelling and whole-genome oligoarrays
We previously showed by 13CO2 host labelling that almost all of the constitutive carbon allocated to the truffles originated from the host. The objective of this present work was to determine the putative capacit...

Climatic variations explain annual fluctuations in French Périgord black truffle wholesale markets but do not explain the decrease in black truffle production over the last 48 years
Production of the black truffle (Tuber melanosporum Vittad.) has experienced a decline in France over the last century. Different sociological factors as well as climate change have been suggested as possible exp...
