Kinetics of IAA redistribution and differential ZMK1 expression during gravistimulation of coleoptiles. (A) Time-dependent IAA redistribution in upper (○) and lower (●) coleoptile halves after gravistimulation. The figure shows the IAA concentration per mg fresh weight (FW, n = 3 ± SE) in segments 0.5–1.5 cm behind the tip (compare with Fig. 5B). (B) Relative transcript content of ZMK1 in upper (open bars) and lower (solid bars) coleoptile halves 0.5–1.5 cm behind the tip after 0, 30, 60, and 90 min of gravistimulation. The mRNA content (n = 3 ± SE) was quantified as described in Materials and Methods. The level of ZMK1 mRNA in the upper half at t = 0 min was set to 1.0 (arbitrary units).
