美国加利福尼亚州的基因工程师开发出一种可存放2～3个月而不会烂的西红柿新品种。生物学家说,用这种西红柿的基因操纵技术,可以用来大大地延长其他水果和蔬菜如香蕉、苹果等的上架时间,还可以推迟花朵的凋谢。科学家向西红柿植株植入基因材料,阻止一个促成西红柿成熟的基因发挥功能。
Genetic engineers in California, USA, have developed a new tomato variety that can be stored for 2 to 3 months without rot. Biologists say using this tomato genetic manipulation technique can be used to greatly extend the shelf life of other fruits and vegetables such as bananas and apples, and delay flower blight. Scientists plant tomato plants with genetic material that blocks the functioning of a gene that causes tomatoes to mature.
