Unlike most animals, plants have the capacity to constantly develop new organs post-embryonically throughout their lifespan. A prime example of this feature is the de novo formation of lateral roots . Lateral roots are formed in a regular pattern along the primary root axis. This regular pattern is ensured by a periodic specification of founder cells. In this project, we aim at dissecting the gene regulatory networks underlying this event in Arabidopsis using cutting edge technologies.
