Well, now I guess I've heard it all! Check out this article about a plant that glows when it's thirsty.
Now as well as the familiar watering jug, you'll have to own a gizmo with which you detect the glow of your thirsty plants. The reason you'll need that tool is that the "glow" is not apparent to the naked eye. Supposedly it should be helpful for farmers, but I'll bet there will soon be a "homeowners version" upon which we can spend our hard earned money.
Tell me, can't you tell when your plants are thirsty? Do we really need to alter the plant's genes in order to use a device which will scan the plant to let us know that it needs water? Come on gardeners, raise your voices in laughter. This sounds pretty lame to me!

It's funny - I thought they glowed when they were NOT thirsty, and looked pale and limp when they were.

Perhaps the device (whatever it is?) could be handy for valuable trees and shrubs which may not necessarily show their stress until too late, when the normal watering may no longer be effective.

My feeling about all of this is that like humans, by time you're thirsty, you're already dehydrated!
A good gardener has good instincts. We need to get that water to our plants BEFORE they're desperate for it! That's why we water heavily before winter sets in and why we water when it's hot! Wouldn't you agree?
