The growth-stimulating effect of ECS is not diminished by 2,3,5-triiodobenzoic acid (TIBA). CPD-antisense 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 grown in parallel. Error bars = ±se. Similar results were obtained for wild-type, dwf1-6, and cbb3 plants (data not shown).
