Scientists are developing ways of making trees glow so they can be used as natural streetlights without the need for electricity. A team of researchers are experimenting with genes to allow the trait that causes fireflies to glow -bioluminescence - to be implanted into a variety of different organisms.
科学家正在研究一种物质可以可以使“植物发光”，将来这种物质未来会代替“路灯”让树木不用任何“电能”产生出自然光造福人类。研究团队通过研究“促使萤火虫发光的基因”而希望能对植物以及不同的有机生物体产生类似的效果。
As well as replacing traditional streetlights, bioluminescent plants would be useful for people who are not hooked up to the electricity grid. And if more lights were ever required, they could simply be grown.
如果研究能成功，这种“荧光树”将会取代传统路灯，而成为依赖“电能”的人类的福音。未来如果人类需要更多光的话，那么种多一点“荧光树”就能达到目的了。
