Fluorescing mosquito larvae. Light micrograph of two genetically-modified Anopheles sp. mosquito larvae glowing under ultraviolet light. Adults of this mosquito carry the disease malaria. A gene for green fluorescent protein (GFP) has been introduced into these mosquitoes. The gene is from the jellyfish Aequorea victoria. Placing a gene from one organism into the genome of another is called transgenics. The glowing GFP shows that the 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. This would save millions of lives. Magnification unknown.
