利用植物基因工程技术,将烟草花叶病毒和黄瓜花叶病毒的外壳蛋白基因通过载体将其拼接到烟草上,实现基因重组,达到同时抗烟草花叶病毒和黄瓜花叶病毒侵染的双抗烟草植株,率先由中国科学院微生物所、河南省农科院植保所和中国农科院烟草所协同攻关培育成功,1992年6月10日在京通过技术鉴定。经十代大田试验证实,利用基因工程方法,培育的双抗优质烟草,烟碱、总氮、香气质量、香型燃烧性等方面均保持了原有优质烟草的品质,而且叶大、株高,亩产量和上等烟的比例都有所提高。历来烟草花叶病毒和黄瓜花叶病毒严重影响我国烟草产量,
Using plant genetic engineering technology, the coat protein genes of tobacco mosaic virus and cucumber mosaic virus are spliced to the tobacco through a vector to achieve gene recombination, so as to achieve the double anti-infiltration resistance to tobacco mosaic virus and cucumber mosaic virus simultaneously Tobacco plants, the first by the Chinese Academy of Sciences Institute of Microbiology, Plant Protection Institute of Henan Academy of Agricultural Sciences and the Chinese Academy of Agricultural Sciences Tobacco Institute coordinated the successful cultivation of breeding, June 10, 1992 in Beijing through technical appraisal. After ten generations of field experiments confirmed that the use of genetic engineering methods to cultivate double-resistant high-quality tobacco, nicotine, total nitrogen, aroma quality, flavor burning and other aspects of the quality of the original high-quality tobacco, and leaves large, Mu production and the proportion of superior smoke have increased. Traditionally tobacco mosaic virus and cucumber mosaic virus seriously affect our country’s tobacco production,
