Rescue of lateral root initiation by globally or locally elevating the auxin level. (A) Number of lateral root primordia (LRPs) and lateral roots (LRs) in InAGN9 seedlings that germinated on MS plates containing DEX or EtOH that had been supplemented with 0.1 μM NAA. Data represent the mean±SD (n=10). (B) Formation of LRPs at the site of curving of DEX- or EtOH-treated roots. Samples were analysed in triplicate (n=15 for EtOH- and n=46 for DEX-treated roots). (C) Formation of lateral roots at the site of curving of roots. (This figure is available in colour at JXB online.)
