[3H]IAA transport (A–C) and histochemical localization of DR5::GUS activity (2h at 37 °C) in root tips (D–F). Seedlings were grown for 2 weeks in hydroponic media containing phosphate (LP, 2 μM; SP, 300 μM) and nitrate (LN, 0.02mM; SN, 2.5mM) with or without 2.5 μM GR24. (A, D) Wild type; (B, E) strigolactone-synthesis mutant d10; (C, F) strigolactone-synthesis mutant d27. RT, root tip; LI, lateral root initiation and emergence zone; LE, lateral root elongation zone; ML, mature lateral root zone. Bars, 1mm. Data are mean±SE. Different letters in the same root zone indicate significant differences (P<0.05, ANOVA) (this figure is available in colour at JXB online).
