草莓镶脉病毒(Strawberry vein banding virus,SVBV)是一种双链DNA病毒,属于花椰菜花叶病毒属,病毒粒子呈球形,直径为45 nm[1]。SVBV基因组全长7 876 bp,包括7个开放阅读框,其编码的蛋白分子量分别为37.8、18.3、16.6、56.0、81.1、59.0和12.6 k Da[2]。SVBV为半持久性蚜传病毒,传毒媒介较多,有草莓瘤钉毛蚜、桃蚜、托马斯毛管蚜等。美国、加拿大、中国、日本、智利、巴西以及欧洲的一 Strawberry vein banding virus (SVBV) is a double-stranded DNA virus belonging to the genus Cauliflower mosaic virus. The virus particles are spherical with a diameter of 45 nm [1]. The full length of SVBV genome is 7 876 bp, including 7 open reading frames. The molecular weight of SVBV is 37.8, 18.3, 16.6, 56.0, 81.1, 59.0 and 12.6 kDa, respectively [2]. SVBV is a semi-persistent aphid-borne virus with more vectors of virus transmission, such as strawberry anemone peach aphid, Myzus persicae and Thomas capillary aphid.
