Key Findings
VOC emission within 30min of damage
Neighbor defense priming 2h pre-contact
Methyl jasmonate as primary signal
Original Abstract
Rosemary plants emit distinct methyl jasmonate profiles within 30 minutes of herbivore damage. Neighboring plants receiving these VOCs upregulate proteinase inhibitor genes 2 hours before physical contact with herbivores, demonstrating airborne defense priming.
