在自然界,能发光的生物有某些细菌、甲壳动物、软体动物、昆虫和鱼类,但能发光的植物却不多见。基因工程的发展使科学家了解到,生物冷光也是由DNA分子中的基因协调控制的基因工程学家已能把发光基因导入植物细胞中,培育出夜晚能发磷光或萤光的植物。 In nature, glowing creatures have some bacteria, crustaceans, molluscs, insects and fish, but plants that glow are rare. The development of genetic engineering made scientists understand that biological cold light is also coordinated by genes in DNA molecules. Gene engineering scientists have been able to introduce luminescent genes into plant cells and produce plants capable of emitting phosphorescence or fluorescence at night.
