Wow, cAMP production appears to be the key for activating canonical auxin signalling, not AUX/IAA degradation!
Also annoying - I need to revise quite a many teaching slides to update auxin signalling 😀

TIR1-produced cAMP as a second messenger in transcriptional auxin signalling - Nature
cAMP produced by the TIR1/AFB receptors of the main endogenous developmental plant hormone auxin acts as a true second messenger, revising the established paradigm of transcriptional auxin signalling.
