Phenolic Biosynthesis

Phenolic biosynthesis refers to the metabolic pathways through which cannabis plants produce phenolic compounds—a broad class of secondary metabolites that includes flavonoids, phenolic acids, and related aromatic molecules. These compounds are synthesized primarily through the shikimic acid and phenylpropanoid pathways, which convert simple precursors into complex structures. Phenolic compounds contribute to plant pigmentation, structural integrity, and aromatic profiles across cannabis genetics. Breeders and researchers study phenolic expression patterns to understand terpene co-expression, pigmentation variation, and chemotype diversity. Selective breeding for specific phenolic profiles has become increasingly relevant in strain development, particularly as cannabis taxonomy moves toward chemotype-based classification.

Breeders monitor phenolic biosynthesis pathways to predict and stabilize aromatic complexity, pigmentation intensity, and secondary metabolite ratios across generations. Understanding phenolic gene expression helps create consistent chemotypes and supports marker-assisted selection for desirable trait combinations.
