Terpene Synthase Activity

Terpene synthase activity refers to the enzymatic processes in cannabis that produce volatile aromatic compounds. These enzymes catalyze the conversion of precursor molecules (geranyl pyrophosphate and farnesyl pyrophosphate) into hundreds of distinct terpenes. Different cannabis lines express varying levels and ratios of terpene synthase enzymes, resulting in distinct aromatic profiles across cultivars. Terpene synthase expression is influenced by both genetic factors and environmental conditions including light, temperature, and nutrient availability. Understanding terpene synthase activity helps breeders identify and stabilize specific aroma characteristics across generations. This enzyme family represents a key biochemical target in cannabis breeding programs focused on aromatic diversity.

Breeders select parent plants with desired terpene synthase activity patterns to concentrate specific aromatic profiles in offspring. Monitoring terpene synthase expression during plant development allows breeders to identify phenotypes that reliably produce target terpene ratios, supporting consistency in seed lines and clone selection.
