Pathogen Response Volatiles
Pathogen Response Volatiles (PRVs) are secondary metabolites plants emit when facing microbial, fungal, or insect pressure. In cannabis, these compounds include terpenes like limonene, pinene, and humulene, which serve defensive roles in living plants. Breeders and cultivators study PRV expression as an indicator of plant vigor and environmental stress tolerance. Understanding this aroma class helps contextualize terpene profiles beyond simple sensory description—they reflect active plant physiology. Documentation of PRV-dominant phenotypes remains limited in formal cannabis research, though cultivation reports frequently note their appearance under specific stressors.

Breeders working in resilience-focused programs monitor PRV expression as a marker for disease resistance and stress response capacity. Selecting for stable, heritable PRV production may support the development of cultivars suited to challenging growing environments.
