About this event
Almost two decades ago, karrikins were identified in smoke as germination stimulants of plants that emerge after fire. Karrikins have since been shown to affect many aspects of plant development, putatively because they mimic an unknown endogenous hormone. I will present our current understanding of how karrikins are perceived by plants and how karrikin signaling is attenuated through feedback control mechanisms.
