Seven gene-edited cuttlefish glow red under fluorescent light
News from Science reports that neuroscientist Tessa Montague produced seven cuttlefish carrying a fluorescent protein gene in every cell. The work, posted as a preprint, is described as the first successful addition of a new gene to a cephalopod.
TLDR
News from Science reports that after six years and thousands of embryos, Montague produced seven cuttlefish that glow red under fluorescent light. Their eggs and sperm carry the gene, and their offspring glow too. The preprint describes the work as the first successful addition of a new gene to a cephalopod. Montague’s longer-term goal is to make neurons fluoresce as they fire, to study how cuttlefish control their camouflage.
