80年代起,基因工程陆续在培育抗病毒植物、抗虫植物、抗除草剂植物,创造植物的雄性不育、培育生产医用蛋白的植物和其他有重要价值的蛋白质的植物以及改变植物的质量性状等方面初露头角,为高产、优质、高效农业的发展展示了诱人的前景。 时至今日,通过向植物转入人类所需要的基因(转基因),得到了一系列符合人类要求的植物(转基因植物)。 一、转基因植物抗病毒 病毒病是植物病害中的一类严重病害,不仅会造成产量大幅度下降,也会影响质量。1986年,美国科学家Beachy等从烟草花叶病毒(TMVUI)株中分离出病毒的外壳蛋白基因,当把这
Since the 1980s, genetic engineering has been one of the hottest projects in cultivating antiviral plants, insect-resistant plants, herbicide-resistant plants, plant-creating male sterility, cultivating plants producing medical proteins and other valuable proteins, and altering plant quality traits And other aspects of emergence, showing an attractive prospect for the development of high yield, high quality and high efficiency agriculture. To date, a series of plants that meet human requirements (genetically modified plants) have been obtained by transforming the genes required by plants into humans (GMOs). First, the transgenic plant antiviral virus disease is a serious disease in plant diseases, not only will cause a substantial decline in output, but also affect the quality. In 1986, American scientist Beachy et al. Isolated the coat protein gene of the virus from tobacco mosaic virus (TMVUI) strain. When this
