据美国报纸报道说，日本科学家正利用遗传基因重组技术，培养抗旱、抗盐和抗冻的“三抗”农作物。报道说，科学家用一种十字花科的芥菜进行了实验。它们在这种芥菜中植入了复制控制基因。这种基因能够促使忍耐恶劣环境的基因发挥作用。仅在干燥和低温的情况下，复制控制基因就 According to the U.S. newspaper reports, Japanese scientists are using genetic recombination techniques to cultivate “three anti-drought” crops that are drought-resistant, salt-tolerant and antifreeze. Reported that scientists conducted experiments with a cruciferous mustard. They implanted replication control genes in this mustard. This gene can contribute to enduring the harsh environment of genes play a role. Only in the case of dry and cold, copy the control gene
