Isoprenoid Pathway

The isoprenoid pathway is a fundamental biochemical process in cannabis that produces a wide range of secondary metabolites, including terpenes, cannabinoids, and flavonoids. This metabolic route begins with simple five-carbon building blocks (isoprene units) and assembles them into increasingly complex molecules. Cannabis plants allocate significant genetic and energetic resources to isoprenoid synthesis, which accounts for much of the plant's distinctive chemical profile. Understanding isoprenoid biosynthesis helps breeders and researchers connect plant genetics to the chemical compounds present in different varieties. The pathway is regulated by multiple genes and environmental factors, making it a key focus for studying chemical diversity across cannabis lineages.

Breeders studying isoprenoid pathway genetics can identify and select for plants that favor different endpoint products—whether targeting higher terpene diversity, specific cannabinoid ratios, or particular flavonoid expressions. Mapping genes involved in isoprenoid regulation allows for more intentional strain development and helps stabilize desired chemical profiles across generations.
