Reconstruction of the phylogeny of the filamentous fungal order Mortierellales (Zygomycetes): A comprehensive taxonomical revision

被孢子菌目的成员构成了接合菌目真菌的一个非凡的类群。其中一些真菌是积累脂质的生物体(如高山被孢霉)，作为花生四烯酸等多不饱和脂肪酸的工业生产者，具有巨大的生物技术重要性。其他种类的被孢霉被认为是不同有机化合物的生物转换剂。本项目的目的是利用不同的显微、生理、分子和生物信息学方法，如电子显微镜和DNA序列分析，对该真菌目进行全面的系统发育研究。这组丝状真菌显示出极高的生态和生理多样性；对所有类型菌株的详细分析可以为合作伙伴和科学界提供具有重要科学和/或实用意义的重要新信息。该项目可能是建立研究这些或类似生物体的研究实验室和菌株收集网络的第一步，它可以为欧盟项目打开致力于接合菌类真菌的欧洲研究小组联合研究应用的大门。

Members of the order Mortierellales constitute a remarkable group of the Zygomycetes fungi. Some of these fungi are lipid accumulating organisms (such as Mortierella alpina) having great biotechnological importance as industrial producers of polyunsaturated fatty acids, like arachidonic acid. Other Mortierella species are known as biotransforming agents of different organic compounds. The aim of the present project is a complete phylogenetic revision of this fungal order using different microscopic, physiological, molecular and bioinformatic approaches, such as electron microscopy and DNA sequence analysis. This group of filamentous fungi shows extremely high ecological and physiological diversity; a detailed analysis involving all type strains could provide important new information of scientific and/or practical importance for both the partners and the scientific community. The project could be the first step towards the building up a network of research labs and strain collections working on these or similar organisms and it can open the door to a joint research application of the European research groups working on Zygomycetes fungi for an EU project.
