Ask HN: Are there plants that can open a window?

There are genetically engineered bacteria that can send a signal when the water gets polluted: http://news.discovery.com/tech/biotechnology/engineered-bacteria-send-a-signal-when-water-gets-polluted-150811.htm

Are there genetically engineered plants that for example emit light in a particular part of the spectrum to directly control valves/actuators in greenhouses to provide them with more or less water, nutrients, etc.?

At first this actuator that is artificially encoded in their genes will not be used as such by the plant itself. However, through evolution the plants that incorporate this genetic circuit in such a way that they can control the lights/water/nutrients will be selected for.
