中国菌寄生属资源、分类及该属的分子系统学研究

菌寄生属真菌物种多样性丰富，通常寄生于其他真菌的子实体上，主要分布于温带和热带地区，在生物医药和工农业等方面具有较高的经济重要性。本项目拟对我国菌寄生属的馆藏标本进行收集和整理，选择具有适宜生境的自然保护区和不同区域的食用菌栽培基地对该属真菌开展补点资源调查、标本采集、菌株分离培养、分类和分子系统学研究。将形态解剖、培养特性、无性型特征和寄主种类等经典生物学性状与多基因联合分析的方法相结合，确定区分物种的关键特征，建立正确的物种概念，全面认识我国菌寄生属的物种多样性和地理分布特点，探讨该属的种间系统发育关系及其在肉座菌科中的地位，为真菌资源利用和生物进化理论研究提供基础信息和科学依据。

Fungi of Hypomyces are worldwide distributed mainly in temperate and tropical regions and parasitic on other fungi, and show high species diversity. They are economically important, especially in biomedicine, industry and agriculture. Through examinations of herbarium materials, collecting specimens from representative areas of China, obtaining pure cultures, and taxonomic treatments of materials of the genus, this study is aimed to explore species diversity of the genus in China, establish clear species concepts and connections between anamorph and teleomorph, reveal host specificity, and distribution range of the group. By using multilocus sequence analyses, the phylogenetic relationships among species of the genus and the position in the family of Hypocreaceae will be revealed. The results will provide useful information to utilization of the nature resources and theoretical evidences for fungal evolution.
