Co-receptor assembly kinetics vary with ligand. A series of commercially relevant synthetic auxins was compared to the IAA response for TIR1 (a) and AFB5 (b). (a) Calculated kd’s for TIR1: IAA500kd = 0.73 × 10–3 s–1; IAA50kd = 1.1 × 10–3 s–1; Fluroxypyr kd = 0.93 × 10–3 s–1; Triclopyr kd = 3.4 × 10–3 s–1; IBA kd = 6.9 × 10–3 s–1. X2 for the set = 0.31. (b) Calculated kd’s for AFB5: IAA500kd = 1.8 × 10–2 s–1; IAA50kd = 3.0 × 10–2 s–1; Fluroxypyr kd = 3.3 × 10–2 s–1; Triclopyr kd = 8.1 × 10–2 s–1; IBA no binding. X2 for the set = 1.81. In all cases a control with no added auxin was included (red).
