中文摘要: 肉座菌科(Hypocreaceae)在世界热带和亚热带地区广泛分布,物种资源丰富。该科包括产生生物活性物质的种类、具有生物防治价值的菌生真菌、以及引起经济植物病害的病原真菌,是子囊菌门的重要类群。我国对该类群的研究虽然有70余年历史,但早期仅有零星报道,近年来对个别属进行过一些研究,但在科的水平上缺乏系统性和全面的工作。本项目拟在前人研究基础上,对我国该类资源进行广泛调查与收集,对获得的材料开展全面的分类研究,遵照新的国际命名法规进行命名方面的清理与订正;在分类学研究基础上,开展该类真菌的补充DNA条形码探索;同时,进行分子系统学研究,探讨肉座菌科的属间与种间演化关系。本项目的研究结果将全面展示我国该类资源的丰富程度,实现物种的快速、准确鉴定,建立正确的物种概念,完善科的系统学;为有益物种的利用提供科学信息,为揭示生物进化规律提供新的科学依据。

英文摘要: Fungi of the Hypocreaceae are widely distributed in tropical and subtropical regions of the world. The family contains fungi producing bioactive compounds, being of biocontrol functions, and causing plant diseases. This is an important ascomycotous group. Studies of the group in China began in the early 1930's when very few sepcies were reported. Although some more records were added to the Chinese fungus flora recently, information about the family of the country is scattered and incomplete. On the basis of the previous researches, this project is aimed at providing a clear overall picture of Hypocreaceae resources from China. Field investigations, re-examinations of herbarium materials, taxonomy, selection of supplementary DNA barcodes, and melecular systematics of Hypocreaceae will be combined to carry out this porposed research. The results of this study will be beneficial and useful to the related theoretical and applied sciences.
