| Research Abstract |
In Arabidopsis thaliana, lateral root (LR) formation is initiated from asymmetric cell divisions (ACDs) of the xylem pole pericycle cells (XPPs) of the parent roots. We show that auxin-inducible LBD16/ASL18 was specifically expressed in a small number of XPP cells before the first ACD and functions redundantly with the other related LBD/ASL proteins in LR formation. Furthermore, the localized activity of auxin-inducible LBD/ASL proteins links to the establishment of asymmetry in the LR founder cells necessary for LR initiation.
