Cannabigerol Pathway

The cannabigerol (CBG) pathway represents the biosynthetic route through which cannabis plants produce cannabigerol, a non-intoxicating cannabinoid that serves as a precursor to major cannabinoids like THC and CBD. In most cannabis strains, CBG exists in relatively low concentrations because it is enzymatically converted into other cannabinoids during plant development; however, selective breeding has produced 'CBG-dominant' or 'CBG-rich' cultivars that retain higher proportions of cannabigerol at harvest. Breeders working in this category typically focus on genetic lines with mutations or polymorphisms in key enzymes (particularly THCA synthase and CBDA synthase) that slow or inhibit downstream conversion. Understanding the CBG pathway is valuable for researchers and seed developers studying cannabinoid biochemistry, plant metabolism, and the genetic mechanisms governing minor cannabino

Breeders pursuing CBG-dominant phenotypes select for plants exhibiting reduced enzymatic activity in the conversion pathways to THC and CBD, often through repeated backcrossing and genetic screening. CBG-rich genetics are also valuable as genetic resources for studying cannabinoid biosynthesis and for crossing programs aimed at creating novel minor-cannabinoid profiles.
