Secondary Metabolite Pathways

Secondary metabolite pathways in cannabis refer to the biochemical routes plants use to produce compounds beyond primary growth and energy needs—including terpenes, phenols, and cannabinoids. These pathways are shaped by genetics, environmental stress, and cultivation conditions, making them central to breeding programs seeking specific chemical profiles. Understanding these pathways helps breeders select for consistency and predict how offspring may express aromatic and chemical traits. Lineage records frequently show that parent plants with active secondary metabolism tend to produce offspring with more pronounced terpene expression. This metabolic activity varies significantly between cultivars and is influenced by both nuclear and cytoplasmic genetic factors.

Breeders working in this category select for plants showing robust secondary metabolite production to stabilize aromatic compounds across generations. Knowledge of these pathways informs decisions about which parent plants are likely to produce chemically diverse offspring.
