摘要

在湖北武昌芝麻上分离到的矮化坏死分离物(DNe-I)侵染芝麻引起严重矮化,叶片皱缩坏死。它能够摩擦接种侵染7科14种植物。在苋色藜、千日红上引起局部坏死斑,侵染油菜和百日菊引起系统花叶和黄化。DNe-I能够被桃蚜、花生蚜以非持久性方式进行传播。病毒体外稳定性状:存活期4天,钝化温度60～65℃,稀释限点4×10~(-4)。提纯病毒为线状粒体,长度为770nm。病毒外壳蛋自为单一亚基组成,分子量为30,700±600D。制备抗血清微量沉淀法测定其效价为1:256。在油菜病组织中,观察到风轮状及长直片层叠聚体类型的胞质内含体。在血清学性质上,该分离物与芜菁花叶病毒密切相关,与花生轻斑驳病毒和花生斑驳病毒弱相关,与大豆花叶病毒和西瓜花叶病毒不相关。基于上述性质,DNe-I被鉴定为芜菁花叶病毒。这是国内芜菁花叶病毒自然侵染芝麻的首次报道。

Abstract

A virus was isolated from diseased sesame (Sesamum indicum) plantwith symptom of dwarf crinkle necrosis both on leaves and stems in Wuchang,Hubei in 1986.The plants of 43 species (cultivars) among 8 families were inoculated withthe virus isolate which can infect those of 14 species involved in 7 families,for instance, infecting Chenopodium amaranticolor, C. oinoa, Gomphrenaglobosa locally and Brassica campestris, Zinnia elegans systemically. My- zus persicae and Aphis craccivora transmitted the isolate in n...
