The genus Tuber, known commonly as 'the true truffles', are highly valued for their delicious and beguiling underground fruit bodies. In spite of their notoriety, taxonomy of Tuber species is still in a confused state. This research will employ multi-locus DNA sequencing approaches to assess phylogenetic relationships and species concepts of Asian, European and North American Tuber species. This research will test whether phylogeographic patterns of Tuber reflect vicariant speciation and whether plant host associations are conserved within clades of Tuber. This research will integrate the majority of known species of Tuber across its natural range, providing a phylogenetic basis for their taxonomy. Many Tuber species are commercially valued and are harvested on a large-scale. A broader impact of this research will be the development of molecular tools to aid in the identification and management of wild and cultivated germplasm. This research will directly contribute toward graduate training for a Ph.D. student, and will also provide unique opportunities for collaborative partnerships between truffle experts from US, Europe and Asia.

块茎属通常被称为“真正的松露”，以其美味而迷人的地下水果体而受到高度重视。 尽管他们臭名昭著，但块茎物种的分类学仍然处于困惑状态。这项研究将采用多洛克萨斯DNA测序方法来评估亚洲，欧洲和北美块茎物种的系统发育关系和物种概念。 这项研究将测试块茎的植物地理学模式是否反映了植物宿主的相关性，以及植物宿主的关联是否在块茎的进化枝内保存。这项研究将在其自然范围内整合大多数已知的块茎物种，为其分类学提供系统发育基础。许多块茎物种具有商业价值，并在大规模上收获。这项研究的更广泛的影响将是开发分子工具，以帮助鉴定和管理野生和培养的种质。 这项研究将直接有助于博士学位的研究生培训。学生，还将为我们，欧洲和亚洲的松露专家之间的合作伙伴关系提供独特的机会。
