Scheres, Ben and Marta Laskowski, Professor of Biology. 2016. "Root Patterning: It Takes Two to Tangle." Journal of Experimental Botany 67 (5): 1201-1203. [review]. "The mechanisms that pattern lateral root primordia are essential for the elaboration of root system architecture, a trait of key importance for future crop breeding. But which are most important: periodic or local cues? In this issue of Journal of Experimental Botany (pages 1411-1420), Kircher and Schopfer manipulate growth direction to demonstrate the importance of both sources of patterning information."
