Caryophyllene Synthase

Caryophyllene synthase is a sesquiterpene synthase enzyme that catalyzes the production of β-caryophyllene (BCP), a major sesquiterpene in cannabis. This enzyme is encoded by genetic pathways active during late-stage flower development and is particularly abundant in resinous trichome tissue. Breeders and researchers have observed that plants with elevated caryophyllene synthase activity often produce cannabis material commonly associated with spicy, peppery, woody, and clove-like aromatics. Understanding the enzymatic basis of terpene biosynthesis helps distinguish naturally high-caryophyllene lineages from other terpenoid profiles, supporting both preservation and directed breeding efforts.

Breeders working in chemotype selection have begun tracking caryophyllene synthase expression as a marker for stable, high-BCP phenotypes. Crosses between lineages with documented caryophyllene-forward genetic backgrounds can yield offspring with predictable sesquiterpene profiles, though environmental stress and harvest timing also influence final enzyme activity and aromatic output.
