Heard about similar experiments a couple of decades ago. Back then scientists immediately stopped the experiment. If glowing plants escape the lab it would seriously affect the natural day-night cycle in nature. Hard to predict what would happen to the night life in the forests. The pitch back then was to colonise space as plants would not need the sun for photosynthesis.

That's a stupid pitch. The light is required as an energy source for the photosynthesis. Making the plant glow would consume energy from the plant. If you could make a plant that glows without an outside energy source and use this light for photosynthesis while still being energy positive, you'd have broken a few fundamental laws of physics. Having these plants escape the lab and light up woods would be the least of my worries in that case.

Apparently this is done by injecting nanoparticles into each mature plant, not by gene-editing, so the plant's offspring won't glow.

I still can't see it being remotely practical as a light source.
