Plant signaling

Deconstructing auxin sensing

Sensing of the plant hormone auxin involves formation of a co-receptor complex consisting of an F-box protein and an AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) transcriptional repressor. Distinct co-receptor combinations might provide cells with an unexpectedly broad range of auxin-sensing capacities and contribute to diverse transcriptional programs activated by different auxin levels in various developmental contexts.
