Terpene Synthase Family

Terpene synthases are the enzyme family responsible for biosynthesizing all cannabis terpenes from precursor molecules like geranyl pyrophosphate (GPP) and farnesyl pyrophosphate (FPP). These catalytic proteins are expressed across different tissues and developmental stages, allowing plants to produce the volatile and semi-volatile compounds commonly tagged in strain chemotypes. The terpene synthase gene family has been partially characterized in Cannabis sativa, revealing multiple isoforms that produce distinct monoterpenes (C10), sesquiterpenes (C15), and diterpenes (C20). Understanding terpene synthase expression helps breeders and researchers recognize how environmental factors, genetics, and plant maturity influence final cannabinoid and terpene profiles.

Breeders working toward specific terpene-dominant phenotypes benefit from knowledge of terpene synthase regulation, as selective breeding can favor lines with higher enzyme activity in desired pathways. Tissue-specific and stress-responsive terpene synthase expression also informs cultivation strategies aimed at optimizing secondary metabolite accumulation.
