Terpenoid Biosynthesis

Terpenoid biosynthesis refers to the biochemical pathways through which cannabis plants produce terpenes—volatile organic compounds responsible for aroma and flavor profiles. These pathways begin with basic building blocks (isoprene units) and are regulated by plant genetics, environmental stress, light exposure, and nutrient availability. Understanding terpenoid production is fundamental to breeding work, as terpene expression directly correlates with strain identity and chemical phenotype. Different cultivars exhibit distinct terpenoid profiles due to variations in enzyme expression and genetic regulation of biosynthetic enzymes. Breeders studying terpenoid biosynthesis can identify and stabilize desirable aroma/flavor combinations across generations. This family encompasses the genetic and enzymatic mechanisms underlying terpene diversity in cannabis.

Breeders working with terpenoid biosynthesis focus on selecting plants with stable, heritable terpene profiles and optimizing cultivation practices that enhance natural terpenoid expression. Knowledge of biosynthetic pathways helps breeding programs identify genetic markers associated with specific terpene ratios and develop cultivars with consistent aromatic identity.
