但发光的绿色植物也能帮助我们了解植物本身,它们是如何新陈代谢的,以及它们对周围环境的反应。
The team worked on two species of tobacco plant. And, unlike previous genetically engineered glowing plants, which used bioluminescent bacteria or firefly DNA, these plants were engineered using the DNA of bioluminescent fungi.
这个团队研究了两种烟草。此前经过基因改造的发光植物利用的是生物发光细菌或萤火虫的DNA,但这些植物不一样,是利用生物发光真菌的DNA改造的。
"Although bacterial bioluminescence genes can be targeted to plastids to engineer autoluminescence, it is technically cumbersome and fails to produce sufficient light," the researchers wrote in their paper.
研究人员在论文中写道:“虽然生物发光细菌基因可以针对质体设计自发光,但技术很复杂,发的光也不够。”
"The caffeic acid cycle, which is a metabolic pathway responsible for luminescence in fungi, was recently characterised. We report light emission in Nicotiana tabacum and Nicotiana benthamiana plants without the addition of any exogenous substrate by engineering fungal bioluminescence genes into the plant nuclear genome."
“真菌发光的代谢途径最近被确定为咖啡酸循环,我们通过将真菌生物发光基因导入植物核基因组就使烟草和本氏烟发光了,无需添加任何外源底物。”
