Within the framework of the Mycorrhizal Genomics Initiative (MGI), we are sequencing a phylogenetically and ecologically diverse suite of mycorrhizal fungi, which include the major clades of symbiotic species associating with trees and woody shrubs. Analyses of these genomes will provide insight into the diversity of nutritional and developmental transitions in mycorrhizal fungi.

More specifically, the genome of Tuber brumale was sequenced as part of a project seeking to densely sample members of the Tuberaceae to examine functional diversity of truffles with a shared evolutionary history.

Tuber brumale – the Winter Truffle

The Winter Truffle (Tuber brumale) belongs to the Tuberaceae (Pezizales, Pezizomycetes). This ectomycorrhizal Ascomycota establishes a mutualistic symbiosis with various tree species and is considered a competitor of the Black Truffle of Périgord (T. melanosporum). This truffle is widespread in Europe and its edible hypogeous ascomata is harvested during Winter. This species is phylogenetically related to T. indicum and T. melanosporum.
