瑞士科学家近日说 ,把黄水仙等植物的基因植入水稻可以提高大米的营养价值 ,从而可以帮助千百万人防止贫血和失明。在实验室中育成这种基因改良水稻的瑞士科学家说 ,这种基因改良方法可以提高水稻所含的铁和维生素Ａ成分 ,并且能抵消大米中所含的阻碍人体吸收铁的一种酸。研究 Swiss scientists recently said that implanting genes from plants such as daffodils into rice would increase the nutritional value of rice and could help millions to prevent anemia and blindness. Swiss scientists breeding such genetically modified rice in laboratories say the genetic modification increases the iron and vitamin A components contained in rice and neutralizes an acid contained in the rice that hinder the human body from absorbing iron. the study
