Metabolic Pathway Regulation

Metabolic pathway regulation refers to the biochemical mechanisms by which cannabis plants control the production and accumulation of secondary metabolites, including cannabinoids and terpenes. These regulatory systems involve enzyme activity, gene expression, and environmental signaling that determine which compounds are synthesized and in what concentrations. Understanding these pathways is foundational to cannabis genetics, as they explain phenotypic variation across cultivars and how genetic lineages express different chemical profiles. Breeders studying metabolic regulation examine how parent plants allocate resources between growth, defense, and cannabinoid/terpene production. This knowledge informs selection strategies for developing cultivars with consistent or novel chemical compositions.

Breeders working with metabolic pathway genetics aim to stabilize desirable terpene and cannabinoid profiles across generations. By selecting parent plants that demonstrate predictable biochemical output, cultivators can work toward consistent secondary metabolite expression in offspring.
