REVSYS: Phylogenetic and Taxonomic Revision of Chytridiales (Chytridiomycota)

合胞菌是游动孢子菌，有320多种。作为藻类的寄生虫以及土壤和水生生态系统中花粉、纤维素、甲壳素和角蛋白的分解者，菊苣对环境具有重要影响，影响初级生产力，是食物链中的关键环节。尽管它们具有重要的生态意义，但人们对它们的生物多样性模式和脊椎动物的进化史知之甚少。在这个项目中，将从美国东南部和墨西哥湾沿岸各州的不同栖息地收集和培养海藻，重点是藻类寄生虫。表型结构的系统发育分析以及多个基因序列将用于鉴定分离株和进行系统发育分析。新发现的物种将被描述和专著。分类摘要，包括互动的关键和插图，将在一个网站上张贴，并在期刊上发表，使这些数据公开访问。许多新的培养物将提供给其他研究人员。将培训一名博士后研究人员，填补chytrid专家的空白，研究生和本科生将学习系统学和生物多样性研究的现代技术。计划参与者将向阿拉巴马州的科学运动高中教师举办研讨会，并将向生命百科全书贡献物种页面，向全球社区扩展蚂蚁的知识。

Chytridiales (=chytrids) are zoosporic fungi comprising over 320 species. As parasites of algae and decomposers of pollen, cellulose, chitin and keratin in soil and aquatic ecosystems, chytrids are environmentally important, impacting primary productivity and serving as critical links in food webs. Despite their ecological significance, patterns of biodiversity and the evolutionary history of chytrids are poorly known. In this project, chytrids will be collected and cultured from diverse habitats in southeastern and gulf coast US states, with an emphasis on algal parasites. Phylogenetic analyses of phenotypic structures, as well as multiple gene sequences, will be used to identify isolates and to conduct phylogenetic analyses. Newly discovered species will be described and monographed.Taxonomic summaries, with interactive keys and illustrations, will be posted on a web site and published in journals, making these data openly accessible. Many new cultures will be made available to other researchers. A post-doctoral researcher will be trained, filling the void of chytrid specialists, and graduate and undergraduate students will learn modern techniques in systematics and the study of biodiversity. Program participants will present workshops to Alabama Science in Motion high school teachers and will contribute species pages to the Encyclopedia of Life, expanding knowledge of chytrids to a global community.
