据《科技日报》1992年11月19日报道,日本植物技术研究所的一个研究小组最近用生物基因拼接技术培育出两个水稻品种,可以抵抗由水稻条纹病毒带来的侵害。他们的报告发表在1992年10月15日出版的《国家科学学术汇编》上。 水稻条纹病毒是由一种名为褐飞虱的昆虫在吞噬作物叶子时带入作物体内的。它会阻碍水稻秧苗的发育,在成熟作物的叶子上产生黄色条纹,还会减少稻种的产量。 为解决这个问题,科学家们将现代生物技术与传统农业技术结合起来。传统的方法叫病毒交叉保护,即在作物幼苗中注射相对良性的病毒,使之阻碍更具破坏力的病毒进入作物体内。生物工程使这一 According to a report by Science and Technology Daily dated November 19, 1992, a team of researchers at the Institute of Botany at the Japanese Institute of Plant Technology recently developed two rice cultivars using biosimilatory splicing to resist the invasion by the rice stripe virus. Their report was published in the National Science and Technology Collection, published on October 15, 1992. Rice stripe virus is introduced into the crop by a species of insect called brown planthopper that swallows the leaves of the crop. It hinders the development of rice seedlings, produces yellow streaks on the leaves of mature crops, and reduces the production of rice seeds. To solve this problem, scientists have combined modern biotechnology with traditional farming techniques. The traditional method is called cross-protection of the virus by injecting relatively benign viruses into crop seedlings, hindering more damaging viruses from entering the crop. Bioengineering makes this one
