      abstract     = {The formation of lateral roots (LRs) is a key driver of
                      root system architecture and developmental plasticity. The
                      first stage of LR formation, which leads to the acquisition
                      of founder cell identity in the pericycle, is the primary
                      determinant of root branching patterns. The fact that
                      initiation events occur asynchronously in a very small
                      number of cells inside the parent root has been a major
                      difficulty in the study of the molecular regulation of
                      branching patterns. Inducible systems that trigger
                      synchronous lateral formation at predictable sites have
                      proven extremely valuable in Arabidopsis to decipher the
                      first steps of LR formation. Here, we present a LR
                      repression system for cereals that relies on a transient
                      water-deficit treatment, which blocks LR initiation before
                      the first formative divisions. Using a time-lapse approach,
                      we analysed the dynamics of this repression along growing
                      roots and were able to show that it targets a very narrow
                      developmental window of the initiation process.
                      Interestingly, the repression can be exploited to obtain
                      negative control root samples where LR initiation is absent.
                      This system could be instrumental in the analysis of the
                      molecular basis of drought-responsive as well as intrinsic
                      pathways of LR formation in cereals.},
