棉铃虫曾是困扰棉花生产的一大难题,转基因抗虫棉的出现为山东省棉花生产带来了曙光。由此本文谈到,许多国家都认为发展转基因植物是突破增产极限、改善食物品质、防止环境污染、生产生物工程药物的重要手段;转基因技术还突破了物种间基因交流的障碍,动物、微生物的基因也可以转给植物,人类迈出了由必然王国走向自由王国的一大步。
Cotton bollworm once plagued cotton production a major problem, the emergence of transgenic cotton has brought the dawn of cotton production in Shandong Province. Therefore, this article states that many countries believe that the development of genetically modified plants is an important means to break through the limits of production increase, improve food quality, prevent environmental pollution and produce bioengineered drugs. Transgenic technology also breaks the barrier of gene exchange among species, animal and microbe Genes can also be transferred to plants, and humankind has taken a major step toward a free kingdom from the necessary kingdoms.
