Plant that glows when thirsty

There are fish that glow in polluted water, fluorescent pigs (and rabbit?)... now students at Singapore Polytechnic have created a plant that can communicate with people by glowing when it needs water.

The students have genetically modified a plant using a green fluorescent marker gene from jellyfish, so that it "lights up" when it is stressed as a result of dehydration.

The light can be seen using an optical sensor developed in collaboration with students at Nanyang Technological University.

The development of such plants could help farmers to develop more efficient irrigation of crops.
