  分子生物学与动物善养研究
• 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 ） 。
• In this study , a new approach of plant virus - resistance was expored by making up the cdna of ppiv . nib gene was amplified from plasmid pysr , which is plant expression vector containing potyvirus y nib gene . the nib gene was fused with the fragment encoding the mature part of papaya proteinase iv
  将番木瓜蛋白酶的cdna序列以全长、去除信号肽部分和成熟酶部分分别连接到细菌表达载体中，表达结果表明，只有含去除信号肽部分cdna的载体才能检测到相应的表达的蛋白条带。
• Up to now , some progress on pathogenic mechanisms and means of management for plant viruses have been achieved . but the ideal ways to control the most common viral diseases , such as mosaic syndrome caused by cmv infection are still unrealized . although the inclusion characteristics of potyvirus in host cells have been well discribed , the pathogenesis of tumv is not yet fully understood
  迄今，对cmv的致病机理和防治研究均取得了一定进展，但仍然不能有效控制其危害；尽管人们已清楚马铃薯y属( potyvirus )病毒在寄主细胞中形成内含体的特征，但是对于该属病毒tumv的致病机理尚缺少全面了解。
