摘要:: 围绕菌根共生体系中菌根真菌与宿主植物的互作机制展开研究，以石斛小菇Mycena dendrobii与铁皮石斛Dendrobium officinale为试验材料，建立二者的共生体系，对其〖JP2〗根系切片进行显微观察，并采用实时荧光定量PCR技术检测石斛基因的表达情况。结果表明：二者能成功形成菌根结构，分支酸合成酶基因和甘露糖特异结合植物血凝素基因在共生早期发生上调，参与了共生的调节。试验旨在为今后阐明菌根真菌与兰科植物的共生机制奠定理论基础。

Abstract:: The study focused on the interaction mechanisms between mycorrhizal fungi and host plants.Taking Mycena dendrobii and Dendrobium officinale as materials，the symbiotic system of M.dendrobii and D.officinale was constructed.The microscopic observation of microsection of symbiont showed that M.dendrobii-D.officinale mycorrhizal symbiont was established successfully.Simultaneously，the chorismate synthase gene and mannose-specific lectin gene were tested using fluorescent quantitative Polymerase Chain Reaction，showing that these genes were up-regulated in early symbiosis stage.The results showed that these genes participate in the regulation of symbiosis.This study laid the foundation for clarifying the interaction molecular mechanisms between orchid and mycorrhizal fungi.
