Metabolic Pathway Markers

Metabolic pathway markers are genetic and biochemical indicators that breeders use to track the biosynthetic routes responsible for cannabinoid and terpene production in cannabis. These markers help identify which enzymatic steps are active in a given plant, informing decisions about phenotype selection and trait inheritance. Understanding metabolic pathways—such as those leading to CBDA synthase or myrcene production—allows breeders to predict offspring chemistry with greater precision. Pathway markers are often identified through molecular genetics studies, lab analysis, or observational breeding records tracking consistent secondary metabolite profiles across generations. This classification is essential for developing stable cultivars with targeted cannabinoid ratios or terpene profiles.

Breeders leverage metabolic pathway markers to select parent plants that reliably express desired chemical outcomes without relying solely on phenotypic observation. By understanding which genetic and enzymatic pathways are active, cultivators can make more informed crosses aimed at amplifying specific secondary metabolites in offspring.
