德国科学家培育出一种转基因玉米,它可以通过释放一种吸引线虫的化学信号从而抵抗破坏性的根虫虫害,而线虫正是甲虫幼虫的天敌。许多植物当受到虫子
German scientists have bred a genetically engineered corn that can resist damaging rootworm pests by releasing a chemical signal that attracts nematodes, which are the predators of beetle larvae. Many plants are affected by insects
