[Ca2+]c in response to auxin and auxin-analogs in 5-d-old Arabidopsis seedlings expressing aequorin in the cytoplasm and reconstituted in vivo with cp-CTZ. Seedlings were placed in a perfusion cuvette. The effector was given at t = 30 min and washed out at t = 90 min as indicated by the black bar. A, Upper trace, 1.0 mm IAA-methylester; lower trace, 0.1 mm IAA-methylester. B, Upper trace, 1.0 mm Na-butyrate; lower trace, 1.0 mm butyrate-methylester. All experiments were performed in KCl, MgCl2, and CaCl2 0.1 mm each with 1.0 mm MES/NaOH at pH = 5.7. All traces are averages of five. sds are given at t = 20, 40, 60, 80, 94, and 120 min.
