Background:

Auxinole is a potent auxin antagonist of TIR1/AFB receptors, binding TIR1 to block the formation of the TIR1-IAA-Aux/IAA complex and so inhibits auxin-responsive gene expression.

Auxinole is a potent auxin antagonist of TIR1/AFB receptors, and binds TIR1 to block the formation of the TIR1-IAA-Aux/IAA complex and then inhibits auxin-responsive gene expression. In addition, Auxinole competitively inhibits various auxin responses in planta[1]. Auxinole causes reduction in IAA-triggered depolarization in root hair cells. Auxinole (20 µM) also represses the transient increase in [Ca2+]cyt completely, and blocks Ca2+ response[2].
