Metabolite Biosynthesis

Metabolite biosynthesis in cannabis refers to the biochemical pathways through which the plant produces secondary compounds—including cannabinoids, terpenes, and flavonoids. These pathways are governed by genetic expression and environmental factors, determining the chemical profile of individual cultivars. Understanding metabolite biosynthesis is central to cannabis genetics research, as it explains how different strain families develop distinct cannabinoid ratios and aromatic signatures. Breeders and geneticists study these pathways to identify which genes regulate terpene production, THC/CBD ratios, and other phytochemical traits. This knowledge underpins selective breeding programs aimed at stabilizing desirable chemotypes across generations.

Breeders use metabolite biosynthesis data to predict offspring chemistry and select parents carrying favorable alleles for cannabinoid or terpene pathways. Mapping biosynthetic gene expression helps stabilize high-CBD or balanced 1:1 THC:CBD lines, and enables targeted development of terpene-rich cultivars.
