Ever wonder how plant roots respond to drought? You probably thought it would be super complex. Turns out a simple change in the development of shoot-borne roots explains much of the architectural differences. In a new paper from the lab published in PNAS we described how grass species suppress crown root growth to slow the extraction of water from soil and preserve this precious resource for a longer time. We think this may allow grass plants to better survive drought. Interestingly, maize and millet still make some crown roots under drought and this may make these domesticated plants more water hungry. Check out the highlight of this work in the BBC!
Our pre-print for Rubén’s manuscript on the GLO-Roots imaging system now available at BioRxiv. It describes an integrated imaging system for studying root architecture, gene expression, root-root, root-soil and root microbe interactions using luminescence reporters. Comments are very welcome!
New review by Neil Robbins II is out online at Journal of Experimental Botany! Review covers the response of roots to moisture at the micro and macro scales and discusses research related to osmo-sensing and hydropatterning in roots. Neil did a great job communicating concepts in physiology with clarity. Enjoy!
