PEET: Monographic Research in Agaricales and Aphyllophorales(Basidiomycotina, Fungi)

9521526彼得森在全世界数以千计的真菌种类中，体型较大、子实体往往很明显的担子菌，例如蘑菇和马鞭草，是比较知名的。尽管如此，它们的分类仍然依赖于地理上的限制处理(按地区或按政治实体)，经常导致科学名称的重复，并往往依赖于可能受到环境改造的形态特征，因此被证明是不稳定的。田纳西大学的罗纳德·彼得森博士召集了一个由同事和贡献者组成的团队，从世界范围内研究蘑菇目和非蘑菇目的几组真菌，并利用几条证据进行分类解析和系统发育分析。这些将包括传统的形态特征(加拿大的Scott Redhead博士和瑞士的Egon Horak博士等同事的贡献)；蛋白质电泳和DNA测序方面的新分子工具(与同事Karen Hughes博士)；实验室培养和交配试验，以评估密切相关物种之间的亲和性反应；以及所有这些将通过使用现有的标本馆收藏和通过在不同地区广泛的实地采集而组装的新收藏来进行。主要将重点放在对金针菇属、金针菇属和香菇属的专题处理上。对研究生和博士后的培训包括课程和研讨会，广泛的实验室和博物馆工作，以及在美国和通常在国外的实地收集。专题工作的许多方面的计算机化，包括标本数据库、形态和分子评价以及识别钥匙的建立，将通过大学的万维网服务器加强成果的传播。

9521526 Petersen Among the thousands of species of fungi worldwide, the larger basidiomycetes with often conspicuous fruiting bodies, the mushrooms and puffballs for example, are comparatively well known. Still, their classification rests upon geographically constrained treatments (by region or by political entity), frequently with consequent duplication of scientific names, and with reliance often placed upon morphological features that are subject to environmental modification and hence prove unstable. Dr. Ronald Petersen at the University of Tennessee has assembled a team of colleagues and contributors to study several groups of fungi in the orders Agaricales and Aphyllophorales from a worldwide perspective, and by employing several lines of evidence for taxonomic resolution and phylogenetic analysis. These are to include traditional morphological characters (with contributions from such colleagues as Dr. Scott Redhead in Canada and Dr. Egon Horak in Switzerland); new molecular tools in protein electrophoresis and DNA sequencing (with colleague Dr. Karen Hughes); laboratory culturing and mating trials, to assess compatibility reactions among closely related species; and all these to be pursued through the use of existing herbarium collections and new collections assembled from extensive field collecting in various regions. Primary emphasis will be given to monographic treatments of the genera Clavicorona, Flammulina, and Lentinellus. Training of graduate and postdoctoral students entails courses and seminars, extensive laboratory and museum work, and field collecting in the U.S. and usually abroad as well. Computerization of many aspects of the monographic endeavor, including specimen databasing, morphological and molecular evaluations, and construction of identification keys, will enhance the dissemination of results through the University's World Wide Web server.
