Terpene Synthase Family

Terpene synthases are a class of enzymes responsible for constructing the volatile organic compounds that define cannabis aroma and flavor profiles. These proteins catalyze the conversion of precursor molecules (geranyl pyrophosphate and farnesyl pyrophosphate) into diverse terpene structures through cyclization and rearrangement reactions. Different terpene synthase variants produce distinct terpenes—limonene synthase yields citrus notes, myrcene synthase produces herbal-piney compounds, and pinene synthase generates conifer-like aromatics. Cannabis breeders and geneticists study terpene synthase gene expression and allelic variation to understand which chemotypes emerge from specific cultivars. The regulation and activity of these enzymes varies significantly across plant tissues, developmental stages, and environmental conditions, making terpene synthase genetics a core focus in canna

Breeders working with terpene profiles commonly select parent plants based on terpene synthase activity patterns to stabilize desirable aroma and flavor compounds in offspring. Understanding terpene synthase polymorphisms helps geneticists predict chemotype stability and develop cultivars with consistent volatile profiles across generations.
