PEO-IAA is an indole-3-acetic acid (IAA) antagonist. PEO-IAA is an auxin antagonist that binds to transport inhibitor response 1/auxin signaling F-box proteins (TIR1/AFBs).
PEO-IAA is also an α-alkyl-IAA, and shows more potent anti-auxin activity in auxin-responsive gene expression and in the cell division and elongation pathway that is mediated via SCFTIR1/AFBs. PEO-IAA suppresses not only the expression of an auxin-responsive ZmSAUR2 gene, but also gravitropic curvature. PEO-IAA blocks the auxin response in Arabidopsis, rice, moss and maize.
