Enzyme Pathway Genetics

Enzyme pathway genetics refers to the hereditary traits controlling metabolic processes that produce cannabinoids, terpenes, and other secondary metabolites in cannabis. These pathways are governed by multiple genes working in sequence, each encoding enzymes that catalyze specific chemical reactions. Breeders studying enzyme pathway genetics examine how plant lineages accumulate or degrade particular compounds through multi-step biochemical chains. This classification is distinct from single-trait inheritance; understanding pathway genetics requires knowledge of gene expression, cofactors, and epistatic interactions. Seed banks and research programs increasingly catalog strains by their enzyme pathway characteristics to predict chemical profiles across generations.

Breeders leverage enzyme pathway genetics to stabilize desirable terpene and cannabinoid ratios without relying solely on phenotypic selection. Mapping which genes control rate-limiting steps in each pathway helps developers predict offspring chemistry and design crosses that combine complementary metabolic profiles.
