Metabolic Pathway Genetics

Metabolic pathway genetics refers to the inherited biochemical processes that govern how cannabis plants synthesize secondary metabolites, including cannabinoids and terpenes. These pathways are controlled by multiple genes that regulate enzyme production and substrate availability throughout the plant's lifecycle. Breeders studying metabolic pathway genetics seek to understand and predict the chemical profiles their crosses will express. This involves tracking genes responsible for key enzymatic steps—such as those converting geranyl pyrophosphate into different terpene families, or CBGA into CBD/THC branches. Modern cannabis breeding increasingly relies on phenotypic observation and selective breeding to stabilize desired metabolic outcomes across generations.

Breeders working in cannabinoid and terpene enhancement focus on metabolic pathway genetics to develop stable, consistent cultivars. Understanding these pathways helps predict which crosses are likely to produce target chemical profiles without relying solely on phenotypic luck.
