Cannabinoid Biosynthesis Pathway
Cannabinoid biosynthesis pathways describe the enzymatic chains through which cannabis plants convert precursor molecules into cannabinoids like CBGA, THCA, and CBDA. These pathways are controlled by genetic loci, particularly synthase genes (THCAS, CBDAS, CBCAS) that determine the ratio and type of cannabinoids produced. Understanding these pathways is fundamental to cannabis genetics because a plant's cannabinoid profile is largely determined by which synthase enzymes are expressed and their relative activity levels. Different lineages and breeding populations show distinct biosynthetic patterns—some populations express high THCAS activity, others favor CBDAS, and many produce balanced or trace amounts of both. Breeders working to stabilize or shift cannabinoid ratios must select for these enzymatic traits across generations.

Breeders use cannabinoid pathway knowledge to predictably shift ratios between major cannabinoids in offspring. Selecting parent plants with known synthase genotypes (THCAS/CBDAS expression profiles) allows controlled development of high-THC, high-CBD, or balanced populations.
