马缨杜鹃菌根真菌的种类组成

摘要

To explore the species of mycorrhizal fungi of R.delavayi,and provide technical reserves for cultivation and application of R.delavayi,the molecular biological method rDNA-ITS-PCR was employed to identify the isolated mycorrhizal fungi of R.delavayi.Results:six kinds of mycorrhizal fungi closely related to ERM were isolated, including Phialocephala sp (CK007137 ), Oidiodendron sp (HM208742.1 ),Oidiodendron sp. shylhs04 (AY268186.1 ), two kinds of different Epacris root associated fungus,which were the relatives of ERM and fungal sp.R38 which was a new type of ERM respectively.%为探明马缨杜鹃菌根真菌的种类，采用 rDNA-ITS-PCR分子生物学方法对分离的马缨杜鹃菌根真菌进行鉴定。结果表明：从马缨杜鹃菌根共分离出6种与杜鹃花类菌根真菌 Phialocephala sp （CK007137）、Oidiodendron sp（HM208742．1）、Oidiodendron sp．shylhs04（AY268186．1）、2个不同的 Ep-acris root associated fungus 类菌株和 fungal sp．R38亲缘关系十分密切的真菌。其中，前5种真菌与其他ERM 植物的菌根真菌同源或近缘，fungal sp．R38是 ERM 植物菌根真菌的新类型。
