项目摘要

9318232 McLaughlin Among the estimated 16,000 species of basidiomycete fungi, the familiar mushrooms and puffballs and bracket fungi of the world, are forms without conspicuous fruiting bodies but possessing microscopic spore-bearing structures. The taxonomic relationships of these numerous fungal forms are little studied, although many economically important crop pathogens and ecologically significant saprobic groups are included here. As well, the phylogenetic or genealogical affinities of these fungi, among themselves and with the ascomycete fungi, are poorly known. New molecular methods of DNA sequencing promise large quantities of comparative data for integration with current morphological and ultrastructural findings for eventual taxonomic and phylogenetic synthesis. Dr. David McLaughlin at the University of Minnesota and postdoctoral associate Dr. Eric Swann have started a major project to acquire DNA sequence data for numerous representatives of the simple septate groups of Heterobasidiomycetes, and to integrate these new molecular data with traditional taxonomic characters. Molecular phylogenetic analyses of the fungi hold great promise for improving taxonomic recognition of the major lines of evolution and for resolving longstanding controversies about the origin and morphological diversification of saprobic and pathogenic groups of basidiomycetes.

9318232 McLaughlin 在估计的 16,000 种担子菌中，世界上常见的蘑菇、马勃和支架真菌是没有明显子实体但具有微观孢子结构的形式。尽管这里包括了许多经济上重要的作物病原体和生态上重要的腐生菌群，但对这些众多真菌形式的分类学关系的研究却很少。同样，这些真菌之间以及与子囊菌真菌的系统发育或谱系亲缘关系也鲜为人知。 DNA 测序的新分子方法有望提供大量比较数据，以便与当前的形态学和超微结构发现相结合，以实现最终的分类学和系统发育合成。明尼苏达大学的 David McLaughlin 博士和博士后助理 Eric Swann 博士启动了一个重大项目，旨在获取异担子菌纲简单隔膜群的众多代表的 DNA 序列数据，并将这些新的分子数据与传统的分类特征相整合。真菌的分子系统发育分析对于改善主要进化系的分类学识别以及解决关于担子菌腐生和致病类群的起源和形态多样性的长期争议具有巨大的希望。
