Terpene Synthesis Pathway

Terpene synthesis pathways describe the biochemical routes cannabis plants use to produce aromatic compounds, beginning with fundamental building blocks like isoprene units and progressing through enzymatic steps to form monoterpenes, sesquiterpenes, and other volatile molecules. Understanding these metabolic pathways is central to cannabis genetics because terpene profiles are inherited traits shaped by specific genes encoding terpene synthases and related enzymes. Lineage records frequently report that distinct cultivars express different pathway emphases—some prioritizing limonene production, others favoring myrcene or pinene accumulation. Breeders working in this category examine these synthesis pathways to predict offspring terpene composition and select for consistent aroma expression across generations. The pathway approach bridges phenotype observation with underlying genetic arc

Breeders leverage terpene synthesis pathway knowledge to design crosses that combine complementary enzyme profiles, increasing the likelihood of stable, layered aroma expression. Selecting parent plants known to activate specific biosynthetic steps allows targeted development of cultivars with predictable volatile profiles.
