组装真菌生命树项目的一个主要目标是创建一个可搜索的数据库，其中包括从已发表的和新的数据中挑选出的超微结构和生化特征，用于系统发育和其他分析。在开发这个数据库时，解决了诸如评估已发表的显微照片中的标本固定质量、组织数据以适应依赖于位置和发育阶段的特征以及要求数据贡献者的责任等问题。描述了隔孔器、核分裂和纺锤体极体周期三个性状的特征状态，并以最简约的方式解决了这些特征状态，并绘制在已知的真菌系统发育关系的概要分支图上。这些分析说明了这些特征的内在系统发育信号，在亚细胞研究中缺乏可比较的特征和特征状态，以及建立一个全面的真菌结构和生化数据库的挑战。
A major goal of the Assembling the Fungal Tree of Life project is to create a searchable database < http://aftol.umn.edu > of selected ultrastructural and biochemical characters from published and new data for use in phylogenetic and other analyses. While developing this database such issues as evaluating specimen fixation quality in published micrographs, organizing data to accommodate characters that were dependent on location and developmental stage, and requiring accountability of data contributors were addressed. Character states for three traits, septal pore apparatus, nuclear division and spindle pole body cycle, are illustrated, and character states are resolved with maximum parsimony and plotted on a summary cladogram of known phylogenetic relationships of the Fungi. The analysis illustrates the inherent phylogenetic signal of these characters, the paucity of comparable characters and character states in subcellular studies and the challenges in establishing a comprehensive structural and biochemical database of the Fungi.
