近几年,科学界提出了一种新的治虫方案,往植物体内插入能够产生毒素的基因,使植物的每个细胞都按基因的指令制造一定量的毒索,当害虫危害作物时被毒杀。 从理论上讲,这种方法有极大的吸引力:可以使选用基因产生的毒素只毒杀害虫,而对鸟类和高级动物毫不损伤;并且不污染环境。 In recent years, the scientific community has proposed a new pest control program, which inserts genes capable of producing toxins into plants so that each cell of the plant produces a certain amount of poisonous cords according to the instructions of the gene. When the pests harm the crops, they are poisoned kill. In theory, this approach is extremely attractive: it can make toxins produced by selected genes toxic to insects, without damage to birds and animals, and without contaminating the environment.
