Cannabinoid Biosynthesis Loci
Cannabinoid biosynthesis loci refer to the chromosomal regions and genetic sequences responsible for the enzymatic pathways that produce cannabinoids like THC and CBD. These loci contain genes encoding key enzymes—such as cannabinoid synthases and their precursor oxidases—that catalyze the conversion of geranylpyrophosphate and olivetolic acid into cannabinoidal compounds. Cannabis plants express variable allelic combinations at these loci, resulting in distinct cannabinoid profiles across strains and cultivars. Understanding these genetic locations is foundational to modern cannabis breeding, as they directly influence the ratio and abundance of major and minor cannabinoids in mature plants. Research into cannabinoid biosynthesis loci has revealed both monogenic and polygenic inheritance patterns, complicating phenotypic prediction in crosses.

Breeders leverage cannabinoid biosynthesis loci data to select for specific cannabinoid ratios, stabilize high-CBD or high-THC lines, and develop novel chemotypes. Marker-assisted selection targeting known loci accelerates the identification of desired genotypes in seedling or early vegetative stages.
