Rapid and reversible root growth inhibition by TIR1 auxin signalling (Nature Plants)
Auxin mediates many of its effects through transcriptional changes via the well-known interaction between its co-receptors and transcriptional regulators (TIR1/AFB – Aux/IAA), but some auxin responses happen too quickly to be explained by transcriptional changes. Fendrych et al. demonstrate that root growth rate slows within 30 seconds of auxin application, and accelerates within 2 minutes […]
