Now, researchers have genetically modified cotton to produce seeds with little or no gossypol. 現(xiàn)在,研究者已經(jīng)研制出轉(zhuǎn)基因棉花,它所結(jié)棉籽的棉子酚含量很少,甚至不含這種毒素。
The earlier version removed gossypol from all parts of the plant, which was then attacked by a variety of insects. 較此更早的一種轉(zhuǎn)基因棉花中任何部分均不含棉子酚,但種植時(shí)招來(lái)多種害蟲(chóng)攻擊。
