巨孢囊霉目(Gigasporales)真菌因其形态特征显著而被认为是较易归类和鉴定的一类丛枝菌根真菌(AMF)。近十余年来随着研究技术的进步,基于无性孢子形态特征而建立的AMF分类、鉴定方法得以不断补充和完善,也使得巨孢囊霉目真菌的系统分类一直处于不断变化和更新的状态。文中主要介绍了该目真菌基于形态特征的鉴定方法上的最新变化以及最新的分类系统,着重归纳已报道科、属、种分类特征,旨在为开展我国AMF资源调查、丰富其多样性提供便利。
The Gigasporales fungi are considered as a class of arbuscular mycorrhizal fungi (AMF) which can be easily classified and identified because of their morphological characteristics. In recent ten years, with the progress of research techniques, the AMF classification and identification method based on the morphological characteristics of asexual spores has been constantly supplemented and improved, and the system classification of giantosporangium fungi has been constantly changing and updating . In this paper, the latest changes in morphological characterization methods and the latest taxonomic classification of this fungus are mainly introduced, and the taxonomic, genera and taxonomic characteristics of the fungi are summarized. The aim is to facilitate the AMF resource survey in China and enrich its diversity .
