Plants can sense increasing resource levels

Posted by hhbruun on 07 Jun 2010 at 06:43 GMT

It has been known for long that plants are able to sense spatial differences in nutrient availability in different parts of the soil, and that they are able to respond to it by deploying new root in nutrient-rich compartments. The new and cool stuff in this paper is that plants can also sense temporal patterns in nutrient availability. And, they can respond to such differences by preferentially deploying new roots in areas with an upward trend in nutrient availability, even when such areas initially have relatively low nutrient availability levels.
