REVSYS: Phylogenetic and Revisionary Systematics of North American Truffles (Tuber, Ascomycota)

该项目支持对属于块茎属(真菌、子囊菌门、小菌目)的北美松露真菌的基本分类研究。松露出产的地下蘑菇被人类和觅食动物广泛用作食用菌；作为菌根真菌，松露也是健康森林生态系统的重要组成部分。这个项目的主要目标是：1)建立一个基于DNA证据的权威块茎物种系统发育分类系统；2)在几个物种复合体和广泛分布的类群中定义分类群；3)整合和分配环境样本(菌根和土壤样本)中的未知块茎物种；4)建立一个北美、欧洲和亚洲物种的数据库，包括描述、数字图像和基于网络的未知松露物种鉴定工具。这将是第一次基于现代方法，使用DNA序列和经典分类学方法来总结我们对全球块菌多样性的知识。该研究项目还将为几名研究生和本科生提供真菌学和分子生态学方面的培训。外联活动包括与业余和商业松露团体的讲习班和伙伴关系，包括开发在线资源。

This project supports basic taxonomic studies on North American truffle fungi belonging in the genus Tuber (Fungi, Ascomycota, Pezizales). Truffles produce underground mushrooms that are widely sought as edible fungi by humans and foraging animals; as mycorrhizal fungi, truffles are also important components of healthy forest ecosystems. The primary aims of this project are: 1) To establish an authoritative phylogenetic classification system for Tuber species based on DNA evidence; 2) To define taxonomic groupings within several species complexes and widely distributed taxa; 3) To integrate and assign unidentified Tuber species from environmental samples (mycorrhiza and soil samples); 4) To establish a database for North American, European and Asian species with descriptions, digital images, and tools for web-based identification of unknown truffle species.This will be the first study to summarize our knowledge of global truffle diversity based on modern methods using DNA sequences combined with classic taxonomic approaches. This research project will also provide training in mycology and molecular ecology for several graduate and undergraduate students. Outreach activities include workshops and partnerships with amateur and commercial truffling groups, including development of online resources.
