【摘要】 国内外已有许多关于芜菁花叶病毒分离株的报道。本文报道了从感病榨菜上得到的一个分离株(TuMVzc)。该分离株对供试的30种植物,能感染其中20种,如心叶烟、普通烟、榨菜、菠菜、萝卜等;不侵染甘蓝、百日草、假酸浆等10种植物。在寄主范围上与以前报道的分离株不同。病毒颗粒大多数为600毫微米长,11-12毫微米宽。感病组织中有无定形及晶状内含体,内含大量病毒,与细胞核邻接。另外又有圆柱状胞质内含体。我们认为TuMVzc是芜菁花叶病毒一个新的分离株。更多还原

【Abstract】 An isolate of turnip mosaic virus (TuMVzc) was isolated from Brassica juncea var. tsatsai in Chongqing, Sichuan province. Twenty of thirty species inoculated by sap were infected. Nicotiana glutinosa, N. tabacum, spinach,, radish can be infected, but cabbage, Zinnia elegans, Nicandra physaloides can not. Differences of some hosts between TuMVzc and other twenty isolates of TuMV which have been reported are found. TuMVzc has straight or slightly flexuous filamentous particles with width 11-12nm and normal length 600nm. Amorphous inclusion bodies near nucleus were observed with light microscope. Both crystal and amorphous inclusions which contained a large number of virus particles were found in ultrathin section. There were some passageways between the inclusion and the vacuole. Laminated aggregates, cylindrical inclusion, were also found in the section. TuMVzc as a new isolate of TuMV is discussed.更多还原
