Enzyme Expression Polymorphism
Enzyme Expression Polymorphism refers to genetic variation in how cannabis plants produce and regulate enzymatic activity, particularly affecting secondary metabolite synthesis. Different cultivars express varying levels of key enzymes involved in cannabinoid and terpene biosynthesis pathways, resulting in distinct chemical profiles from genetically similar lineages. This polymorphism occurs due to allelic variation and differential gene regulation rather than major structural mutations. Breeders and geneticists study these expression patterns to understand how plants produce divergent chemotypes—such as high-THC versus high-CBD phenotypes—from related parentage. Documentation of enzyme polymorphisms helps explain why sibling plants can develop markedly different terpene and cannabinoid ratios under identical cultivation conditions.

Understanding enzyme expression polymorphism allows breeders to select parents showing desired metabolic output without relying solely on phenotypic screening. Identifying cultivars with consistent expression profiles for target enzymes (such as those favoring limonene or myrcene production) supports development of more reliable, reproducible strain lines.
