日本北海道农业试验场利用生物工程技术,对黄瓜花叶病毒的核糖核酸进行部分置换,试制成疫苗,对危害较大的番茄的黄瓜花叶病毒病进行防治,取得了良好的效果。黄瓜花叶病毒虽有几种类型,但是,其基因都是由五个核糖核酸所组成的,其中四个核糖核酸传递病害特征的遗传信息,一个是起控制病状作用的卫星核糖核酸。在引起番茄卷 Japan’s Hokkaido agricultural experiment site using bio-engineering technology, partial replacement of cucumber mosaic virus RNA, trial-made vaccine, the cucumber mosaic virus to control more harmful diseases, and achieved good results. Although there are several types of cucumber mosaic virus, its gene is composed of five ribonucleic acids, of which four transmit the genetic information of disease characteristics and one is the satellite RNA that controls the disease.
