Genetically modified mosquito larvae. Larvae of the mosquito (Anopheles stephensi), glowing green under ultraviolet light. The gene for enhanced green fluorescent protein (EGFP), has been introduced into the mosquito genome. EGFP is a version of the green fluorescent protein (GFP) from the jellyfish Aequorea victoria that had been mutated in the lab to give a brighter glow. The green glow shows that the EGFP gene has been successfully introduced. This raises hopes that a gene could be introduced that would make the mosquitoes unable to carry the Plasmodium sp. protozoa that cause malaria, which would save millions of lives.
