Effects of 100 μm 2,3,5-triiodobenzoic acid (TIBA) in the presence and absence of 10 nm ECS. Plants were grown on vertically oriented plates, and root length was measured 20 ± 1 d after sowing. Relative root lengths are given as the percentage of root length of untreated wild-type plants. Error bars = ±se.
