Turnip mosaic virus ( tumv ) is a member of the potyvirus genus . it occurs worldwide and can infect more than 300 species in 156 genera of 43 plant families . it was found to be one of the most important ( only second to cucumber mosaic virus ) 芜菁花叶病毒( tumv )是植物病毒中最大的属? ?马铃薯y病毒属的一个重要成员,在世界范围内广泛分布,能侵染43科、 156属的300多种植物,其为害仅次于黄瓜花叶病毒( cmv ) 。
Dsmv is proved as the predominating virus - pathogen on aroid plants from zhejiang province and other regions in china . cdna of dsmv rna 3 " end partial sequence and subgenomic rna promoter region of cucumber mosaic virus ( cmv ) rna3 were used as probes for detection of dsmv and cmv respectively . total rna extracted from field samples were used for rna dot - hybridization 用侵染马蹄莲的dsmv3末端序列和黄瓜花叶病毒( cmv )的亚基因组启动子区互补dna序列为标记探针,对自然感病的天南星科植物进行rna斑点杂交,并结合双链rna分析、病毒提纯和形态学观察,对杭州等地16属天南星科植物的81个样品进行了病毒鉴定。
