Researchers have genetically engineered silkworms to produce colored fluorescent silks, which are starting to be used in textiles, including in a wedding dress created by Japanese designer Yumi Katsura

The researchers inserted glowing proteins, borrowed from corals and jellyfish, into the silkworm genome near the gene for the silk protein fibroin.

They then raised more than 20,000 transgenic silkworms, which expressed fibroin proteins with the fluorescent molecules attached.
