Plant biotech is a set of techniques used to adapt plants for certain needs. With glow-in-the-dark trees, bushes, and grass, neighborhoods and urban spaces could be illuminated without the need for electricity, while also reducing light pollution.
BioGlow, a small biotech firm in St. Louis, has experimented with various types of plants, including the tobacco plant, to increase light output. This has been done by combining the plant's current genes with bioluminescent bacteria.
This has been the topic of scientists’ work for at least 10 years. However, the improvement and widespread use of glowing plants may not become achievable until the late 2030s.
