Cornell researchers have found a new method plants use to regulate water under the leaf's surface, in addition to stomata on the leaf's surface. This discovery could potentially result in the breeding of more drought-tolerant crops. The study utilized AquaDust, a nanoscale sensor created by Cornell, to measure water levels inside leaves. This breakthrough in understanding plant water regulation could be crucial in developing climate-resilient agriculture practices and addressing water scarcity challenges in the face of climate change.
