  text: Root system architecture depends on lateral root (LR) initiation that takes
    place in a relatively narrow developmental window (DW). Here, we analyzed the
    role of auxin gradients established along the parent root in defining this DW
    for LR initiation. Correlations between auxin distribution and response, and spatiotemporal
    control of LR initiation were analyzed in Arabidopsis thaliana and tomato (Solanum
    lycopersicum). In both Arabidopsis and tomato roots, a well defined zone, where
    auxin content and response are minimal, demarcates the position of a DW for founder
    cell specification and LR initiation. We show that in the zone of auxin minimum
    pericycle cells have highest probability to become founder cells and that auxin
    perception via the TIR1/AFB pathway, and polar auxin transport, are essential
    for the establishment of this zone. Altogether, this study reveals that the same
    morphogen-like molecule, auxin, can act simultaneously as a morphogenetic trigger
    of LR founder cell identity and as a gradient-dependent signal defining positioning
    of the founder cell specification. This auxin minimum zone might represent an
    important control mechanism ensuring the LR initiation steadiness and the acropetal
    LR initiation pattern. © 2011 The Authors. New Phytologist © 2011 New Phytologist
