英、德、日等国科学家合作培育出一种转基因西红柿,其中胡萝卜素含量最高可达普通西红柿的3.5倍,有利于为人体补充维生素A。英国伦敦大学的彼得·布拉姆利教授及其外国合作者将一种细菌的基因植入西红柿,使西红柿中的八氢蕃茄红素转化为蕃茄红素,后者对合成胡萝卜素非常重要。 Britain, Germany, Japan and other countries scientists to cultivate a genetically modified tomatoes, including carotene content of up to 3.5 times the average tomato, is conducive to vitamin A supplement for the human body. Professor Peter Bramley of the University of London in the United Kingdom and his foreign collaborators planted a gene of bacteria into tomatoes and turned the ochradine lycopene in tomatoes into lycopene, which is important for the synthesis of carotenoids.
