Secondary Metabolite Pathways

Secondary metabolite pathways are biochemical processes through which cannabis plants synthesize compounds beyond those required for basic growth and survival. These pathways produce cannabinoids, terpenes, flavonoids, and other specialized molecules that vary significantly across cultivars and environmental conditions. Understanding these pathways is essential for cannabis genetics work, as they determine the chemical profile breeders can select for across generations. Research into secondary metabolism has revealed that expression of these compounds is controlled by multiple genes, environmental factors, and developmental stages. Breeders working with secondary metabolite traits often assess plant tissue at specific growth phases to identify genetic potential. This classification encompasses the genetic and biochemical mechanisms underlying strain diversity.

Breeders use secondary metabolite pathway knowledge to select parent plants with desired terpene or cannabinoid profiles, as these traits are heritable and responsive to selective breeding. Understanding pathway regulation helps breeders predict offspring chemistry and develop cultivars with consistent secondary metabolite expression across generations.
