项目摘要

9304086 Andersen Advances in electron microscopy and in molecular analyses of DNA have renewed interest in many aspects of the biology of protists (unicellular algae, fungi, and protozoa). Two primary reasons are their roles in bridging the evolutionary gap between prokaryotes (bacteria) and the multicellular plants and animals, and their roles as model experimental systems in cell and molecular biology. Despite the interest of many biologists in the phylogeny of protists, few scientists have addressed the basic problems in terminology and homology that were created by the classical academic separation of the fields of phycology, mycology, and protozoology. In an attempt to resolve problems in communication and synthesis, a NSF sponsored task force was established in 1987. The Cell Surface Components Task Force will complete its studies this year, and it will present its findings at the 1993 American Institute of Biological Sciences annual meeting. Leading national and international scientists will participate in two symposia that summarize recent advances in the study of protistan cell surfaces. Proceedings of the meetings and additional solicited review papers will be published in international journals. %%% Experts in the biology of unicellular algae, fungi, and protozoa will meet at the annual meetings of the American Institute of Biological Sciences to synthesize recent ultrastructural and molecular data on protis tan organisms. The principal goal is to synthesize a single, coherent terminology for homologous features of protistan cell surfaces, hitherto obscured by the separate academic traditions of studying these organisms in phycology, mycology, and protozoology departments.

9304086 Andersen 电子显微镜和 DNA 分子分析的进展重新引起了人们对原生生物（单细胞藻类、真菌和原生动物）生物学的许多方面的兴趣。两个主要原因是它们在弥合原核生物（细菌）与多细胞动植物之间进化差距方面的作用，以及它们作为细胞和分子生物学模型实验系统的作用。尽管许多生物学家对原生生物的系统发育很感兴趣，但很少有科学家解决了由藻类学、真菌学和原生动物学领域的经典学术分离所造成的术语和同源性方面的基本问题。为了解决通讯和合成方面的问题，一个由 NSF 赞助的工作组于 1987 年成立。细胞表面成分工作组将于今年完成其研究，并将在 1993 年美国生物科学研究所年会上展示其研究结果。国内外领先的科学家将参加两次研讨会，总结原生生物细胞表面研究的最新进展。会议记录和其他征集的评论论文将在国际期刊上发表。 %%% 单细胞藻类、真菌和原生动物生物学专家将在美国生物科学研究所年会上齐聚一堂，综合有关原生生物的最新超微结构和分子数据。主要目标是为原生生物细胞表面的同源特征合成一个单一的、连贯的术语，迄今为止，这些术语被藻类学、真菌学和原生动物学部门研究这些生物体的不同学术传统所掩盖。
