花色是给人们的第一印象,人们看花,首先是观花色。花色丰富多彩是转基因花卉的一个重要特征。现在人们已经能够通过转基因技术任意改变和调整花的颜色。首次成功地进行花卉颜色遗传工程实验的是德国科学家。他们将能制造花葵素(天竺葵的砖红颜色)的一种酶的基因转移到矮牵牛花中。后来,由荷 Color is the first impression to people, people see flowers, the first is the concept of flowers. Variety of colors is an important feature of genetically modified flowers. Now people have been able to change and adjust flower color arbitrarily by transgenic technology. The first German scientists to successfully carry out floral color genetic engineering experiments. They transferred the gene that encodes an enzyme that produces pelargonid (the reddish-brown color of geranium) into petunia. Later, by the Dutch
