From: The piperazine compound ASP activates an auxin response in Arabidopsis thaliana
Effects of ASP in Arabidopsis auxin signaling mutants. Wild-type and tir1–1, axr2–1 and aux1–7 mutants were grown on 1/2 MS medium supplemented with 4 μM ASP for six days. DMSO was used as control. a: Hypocotyl length. b: Primary root length. Data of A and B represent Means ± SD (N = 30, P < 0.05). c: Root hair number. d: Root hair length. Data of C and D represent Means ± SD (N = 3, P < 0.05). The experiment was repeated three times with similar results. * P < 0.05, ** P < 0.01, *** P < 0.001 or different letters indicate means statistically different at P < 0.05
