Pathogen Detection

Pathogen Detection is not a terpene itself, but rather a descriptive term sometimes used in cannabis breeding to reference volatile organic compounds (VOCs) and secondary metabolites that plants produce in response to microbial stress or infection. Cannabis plants, like many species, generate characteristic chemical profiles when exposed to fungal, bacterial, or viral threats—these defensive compounds can include elevated levels of sesquiterpenes, phenolics, and other trace volatiles. Breeders and cultivators monitoring plant health may reference 'pathogen detection signatures' when observing shifts in aroma or chemical expression that suggest disease pressure. This concept intersects with terpene science because terpene production itself is often upregulated during plant stress responses, making volatile fingerprinting a potential cultivation tool rather than a consumable trait.

Plant geneticists and breeders working on disease resistance programs sometimes map stress-response terpene profiles to identify cultivars with robust defensive chemistry. Understanding these VOC signatures helps differentiate between healthy plants and those under pathogenic pressure during selection.
