Transgenic Plant
Low temperatures induce the expression of many cold-induced genes. Transgenic plants with improved cold tolerance have been produced by

expressing the protein that activates expression of these genes all the time in plants
cooling plants using the Peltier effect
expressing a gene for production of antifreeze (ethylene glycol) in plants
increasing evaporative cooling from leaf surfaces
