Transformed Taters

Researchers managed to genetically engineer a gene from a fluorescent jellyfish into a potato. Why? The gene that makes something glow (fluoresce) is tied to the potato plant's need for water. When the plant is low on water, the gene turns on and the plant glows green, signaling the farmer to water it. These transformed taters would be sprinkled throughout the regular crop, serving as low-water or drought signals. The glowing plants would be removed before harvest so they wouldn't be consumed.
