Secondary Metabolite Regulation

Secondary metabolite regulation refers to the genetic and biochemical mechanisms controlling production of cannabinoids, terpenes, and flavonoids in cannabis. Unlike primary metabolites (sugars, proteins, amino acids) necessary for basic plant survival, secondary metabolites accumulate in trichomes and contribute distinctive chemical signatures. Cannabis breeders working in this category focus on heritable traits governing when and how intensively these compounds are synthesized during flower development. Understanding regulation pathways helps explain why genetically related plants can express vastly different chemotypes despite identical environmental conditions. Lineage records frequently report secondary metabolite diversity emerging from single-parent selections, suggesting complex polygenetic inheritance. This family remains central to modern breeding as cultivators seek stable, pr

Breeders targeting specific cannabinoid ratios or terpene dominance work directly with secondary metabolite regulation traits, attempting to stabilize and intensify expression across generations. Crosses combining complementary regulation alleles often yield offspring with enhanced or novel metabolite accumulation patterns.
