在大多数苗圃的花架上,我们可以看到各色各样的花朵,它们像彩虹一样绚烂多姿——黄色的、白色的、粉红色的、紫色的、红色的,还有绿色的。但在花的世界里,有一种颜色却很不寻常——就像蓝月亮一样。是什么使牵牛花长出了蓝色而不是该植物为人熟知的典型的红色或紫色花瓣?如今,科学家揭开了其中的秘密。他们发现,蓝色牵牛花是基因突变的结果——植物细胞内的两个“泵”失去了作用。通常情况下,这两个“泵”能确 On the shelves of most nurseries, we can see a variety of flowers that are as colorful as the rainbow - yellow, white, pink, purple, red, and green. But in the world of flowers, one color is unusual - just like Blue Moon. What made typical petals of red or purple petals that make morningglory blue instead of the plant? Today, scientists have uncovered the secrets. They found that blue morning glory was the result of a genetic mutation - the two “pumps” in plant cells lost their effect. Under normal circumstances, these two “pump ” can be sure
