1. The document discusses developing glowing plants through inserting luciferase genes from bioluminescent bacteria into plants. This could create natural street lighting and reduce CO2 emissions. 2. Luciferase produces a chemical reaction that causes bioluminescence in fireflies. Researchers aim to transfer the bacterial luciferase-luciferin system, including the lux operon genes, into plants like tobacco through Agrobacterium-mediated transformation. 3. Experiments have shown that luciferase expression can vary in transgenic tobacco plants depending on DNA insertion location, with expression in some veins but not others. This demonstrates challenges in stable, uniform luciferase expression across plant tissues.
