8th Biennial Meeting of the International Society for Evolutionary Protistology; College Park, MD; July 1990

原生生物是一组不同的真核生物，包括藻类、真菌和原生动物，它们的中间组织水平介于原核生物(细菌和蓝藻)和更有组织的动植物群体之间。在细胞生物学的实验室研究中，原生生物通常被用作实验有机体。藻类、真菌和原生动物是由不同的研究人员群体研究的，这一事实阻碍了对原生生物群体之间进化关系的理解。然而，在过去几年里，已经组织了几个工作队，研究这三个组之间的相似和不同之处，并为它们共有的结构建立标准命名法。这项仔细的研究应该允许研究人员将源于共同祖先(同源)的相似之处与因共同功能(类比)而引起的相似之处分开。即将完成的第一项工作是鞭毛器和细胞骨架问题工作队。研究结果将在马里兰州大学公园举行的第八届国际进化原生动物学会会议上公布。拟议的工作队会议及其相关议事录将产生广泛影响。这一合成将在细胞生物学家、进化生物学家和研究藻类、真菌和原生动物的系统学家之间展开新的讨论。这些发现将有助于为更好地理解高等生物的古代多样性扫清道路。

The protists are a diverse group of eucaryotic organisms, including the algae, fungi, and protozoa, united by their intermediate level of organization between the procaryotes (bacteria and blue-green algae) and the more highly organized groups of plants and animals. Protists are commonly used as experimental organisms in laboratory studies of cell biology. Understanding the evolutionary relationships among protists groups has been impeded by the fact that algae, fungi, and protozoans are studied by separate communities of investigators. During the past few years, however, several Task Forces have been organized to study the similarities and differences across the three groups, and to establish standard nomenclature for structures that are shared by them. This careful study should allow investigators to separate similarities that are due to common ancestry (homologies) from similarities due to common function (analogies). The first such effort to be completed is the Task Force on the Flagellar Apparatus and the Cytoskeleton. The results will be presented at the 8th meeting of the International Society of Evolutionary Protistology, in College Park, Maryland. The proposed Task Force meeting and its associated proceedings volume will have wide impact. This synthesis will open new discussions between cell biologists, evolutionary biologists, and systematists working of algae, fungi, and protozoans. These findings will help to clear the path leading to a better understanding of the ancient diversification of higher organisms.
