Scotland's Edinburgh University produced a genetically engineered potato that has its leaves glow when it needs water.

Researchers added a jellyfish gene to the potato plant in the five-year-old project. The glowing foliage can be seen through a special hand-held device.

The scientists at the university's Institute of Cell and Molecular Biology said the breakthrough would make food production more efficient and cost effective by reducing the over use of water.

They said the technology could be used with other root vegetables as well.
