There are glow in the dark plants (<a href="http:&#x2F;&#x2F;www.glowingplant.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.glowingplant.com&#x2F;</a>) but there are not plants genetically engineered to produce photosynthetically useful light that I know of. And they definitely don&#x27;t exist in anything close to a commercially useful form.<p>I&#x27;m not really sure how the text of your question relates to the headline though. There are plants that can open a window as they grow over time, but there isn&#x27;t a plant that can just do it in response to stimuli.<p>I&#x27;m not sure how useful this technology would be when it&#x27;s already so easy, low cost, and sustainable to incorporate it mechanically without the added regulatory, r&amp;d, and cost hurdles associated with genetic engineering. I would also mention GE issues with patents and environmental damage.
