β‐Caryophyllene Competes With NINJA/IAAs for TOPLESS Family Corepressors to Regulate Plant Physiological Activities

Summary statement β‐caryophyllene (BCP) plays diverse roles in plants, particularly in resistance induction and plant‐plant communication. This study reports the underlying mechanism: BCP competes with NINJA and IAA1/IAA10 for TOPLESS binding, thereby relieving the repression of JA and auxin signalling pathways.
