笃斯越橘菌根真菌多样性

Mycorrhizal fungi diversity of Vaccinium uliginosum L

摘要:

摘要:【目的】为了了解大兴安岭北部地区野生笃斯越橘的菌根真菌多样性状况。【方法】采用形态学和rDNA ITS序列分析相结合的方法。【结果】从笃斯越橘根样中分离得到的真菌分为6个类群:膜盘菌属(Hymenoscyphus)、Phialocephala、粒毛盘菌属(Lachnum)、Cadophora、担子菌小皮伞属(Marasmius)和担子菌小菇属(Mycena)。子囊菌Ascomycotina 占87.10%，担子菌Basidiomycotina 占12.90%。【结论】与笃斯越橘根共生的真菌类群较丰富，且是一个异源的群体，这些共生真菌在笃斯越橘的整个生长期的侵染时间不同。

Abstract:［Objective］The diversity of mycorrhizal fungi isolated from Vaccinium uliginosum L in the northern region of Daxing’anling mountains was examined for the first time.［Methods］Morphology and ITS sequence analysis were used to identify the fungal communities.［Results］Six groups of fungi were isolated from Vaccinium uliginosum root samples: one belongs to Hymenoscyphus; one to Phialocephala; one to Lachnum; one to Cadophora; one to Marasmius and one to Mycena．Among them，87.10% belong to ascomycetes and 12. 90% belong to Basidiomycotina.［Conclusion］ The diversity of fungi associated with Vaccinium uliginosum is abundant and the fungi are from heterogenous group.
