The isolates were isolated from beet in Xinjiang. After they are inoculated to beet induce ring spot and line Patters along vein of leave. The ring spot and line patterns is eventually formed into necrosis. The virus particles are icosahedra and about an averege of 28 nm in diameters

在新疆甜菜的根部和叶片分离到两种病毒分离物。回接到甜菜上均产生环斑和沿脉线纹。最后形成坏死斑。病毒粒体为20面体,平均直径28nm。除侵染甜菜外还侵染苋色藜,昆诺阿藜、番杏、菠菜等,引起局部坏死斑,在普通烟、心叶烟、菜豆、黄瓜、番茄上无症状侵染,病毒致死温度为70℃,10分钟,体外存活期13天以上,冻干病叶三年后仍有侵染力。通过PEG沉淀。差速离心,琼脂糖柱层折及蔗糖梯度离心,可得到较高浓度的纯化病毒,病毒的紫外吸收最低值在245nm,最高值在260nm。病毒外壳蛋白的分子量为54000道尔顿,病毒基因组核酸为两个组份。在琼脂双扩散实验中,能与番茄黑环病毒(TBRV)抗血清产生较弱的沉淀线,与黄瓜花叶病毒(CMV),烟草坏死病毒(TMV)。烟草环斑病毒(TRSV)不发生反应,从上述结果可以初步认为这两种分离物为番茄黑环病毒侵染甜菜的一个株系。

wo virus isolates were found in beet in Xinjiang.After they are inoculated to beet the isolates induced yellow ring spot and line patterns along vein of leave.The rmgspot and line patterns eventuallyformed necrosis.The virus infected Chenopodium amaranticolor C.quinoa, Telragnia axpansa and Spinacia oleracea and induced local necrotic leeions.The virus infected Nicltiana tabacum,N. glolionosa,Pelunia hy brida,bean,cucumber and tomato but without showing symptoms.The virus particles have icosahedramorphology with an averege diameter of 28nm,In sap the virus thermal inactivation point(10min)is70℃.Infectivity is retained for 13 days at room temperatue about 20℃ and for 7 years in refrigerat ed dry leaves.The highly purified virus is easily obtained from C.amaranticolor by precipitation withPEG and differential centrifugation,Absorption spetrum of the virus is maximum in 260nm and minimum in 245nm.Protein subunits have M,W.27000.Cenome nucleic acid of the virus consists of three species with sizes of 3.08kb,1.28kb and 0.85kb,respectively,In the agar-double-diffusiontest,the virus reacted tomoto black ring virus antiserum,the faintly precipitation lineis observed, but we did not see reaction of the viurs to antiserum of tabacco ring spot virus,carnation ring spot virus,tabacco necrotic virus,cucumber moseic virus.

在新疆甜菜的根部和叶片分离到两个球状病毒分离物。从病毒形态、生物学及物化性质等研究结果证明这两个分离物实是一种病毒。病毒粒体力20面体,直径约28nm,回接到甜菜上产生环斑和沿脉线纹最后形成坏死斑。此外还侵染苋色藜,昆诺阿黎,番杏,菠菜等,引起局部坏死斑。在普通烟,心叶烟,菜豆,黄瓜,蕃茄上无症状侵染,病毒致死温度为70℃,10分钟。体外存括期13天以上,冻干病叶7年后仍有侵染力。通过PEG沉淀、差速离心、琼脂糖柱层析及蔗糖梯度离心,可得到较高浓度的纯化病毒,病毒的紫外吸收最低值在245nm,最高值在260nm。经SDS-PAGE测定,病毒外壳蛋白的分子量为2.7×10 ̄4道尔顿,病毒基因组核酸为三个组份,分子量分别为3.08kb,1.28kb和0.85kb。在琼脂双扩散实验中,能与番茄黑环病毒(TBRV)抗血清产生较弱的沉淀线,与黄瓜花叶病毒(CWV)、烟草环斑病毒(TRSV)、烟草坏死病毒(TNV)、香石竹环斑病毒(CaRSV)的抗血清不发生反应。

During 1995~1998,the author had made investigation about beet mosaic disease in the main productive region of beet in Xinjiang,191 samples were obtained and identified.The results indicate,there are four types of beet mosaic diseases,distributing in different places and caused by different viruses.These viruses are Beet Mosaic Virus,Cucumber Mosaic Virus and an isolate of Furoviruses.This is the first report of CMV maturally infecting sugarbeet in China.

1995~ 1 998年对新疆甜菜主产区甜菜花叶病的发生进行了调查 ,采集花叶标样 1 91个 ,并对毒原种类做了分离鉴定。结果表明 ,甜菜花叶病有 4种症状类型 ,且有不同的地区分布 ,又由不同的病毒侵染所致。这些病毒是甜菜花叶病毒 ( BMV) ,黄瓜花叶病毒 ( CMV)和真菌传杆状病毒属 ( Furoviuses)分离物。CMV自然感染甜菜在国内尚属首次报道。
