Terpene Synthase

Terpene synthase is an enzyme class responsible for synthesizing terpenes—the volatile organic compounds that create cannabis aromatics. These enzymes catalyze the conversion of precursor molecules (geranyl pyrophosphate and farnesyl pyrophosphate) into the diverse terpene structures found across cannabis cultivars. Different terpene synthase variants produce different end products, meaning genetic variation in these enzymes directly influences which aromatic profiles appear in a plant. Cannabis breeders and researchers study terpene synthase activity to understand how lineages develop characteristic scent signatures. Expression levels and enzyme efficiency vary among strains, contributing to the range of terpene ratios observed in the cannabis genome.

Breeders working with terpene profiles examine terpene synthase genes and their expression patterns to select for or away from specific aromatic characteristics. Understanding synthase activity helps explain phenotypic consistency within families and informs crosses aimed at novel terpene combinations.
