CEP peptides provide a new paradigm for improving N-fixation and root shape

Two pivotal goals of agronomic research are to extend the benefits of symbiotic nitrogen fixation resulting from legume interactions with rhizobia, and to improve root architecture so that plants more effectively acquire nutrients and water. This project aims to discover new regulators that are central players in both processes. Applying these regulators to roots should enable legumes to nodulate more, to fix more nitrogen, and to fundamentally alter important aspects of root architecture. Thus, these regulators will be used to enhance nitrogen fixation more widely in legumes and to alter their root architecture to enhance growth. These regulators may find wide utility in improving agriculture in developed and developing countries.
