Auxinole is a potent auxin antagonist that binds to TIR1 and blocks the formation of the TIR1-IAA-Aux/IAA complex. Auxinole is an OsTIR1 inhibitor that suppresses leaky degradation of degron-fused proteins.
Auxinole causes reduction in IAA-triggered depolarization in root hair cells. Auxinole (20??M) also represses the transient increase in [Ca2+]cyt completely, and blocks Ca2+ response.[4]
