Gppp Precursor Pathway
The GPPP (geranyl pyrophosphate) precursor pathway is a fundamental biochemical route in cannabis that generates the substrate for monoterpene and sesquiterpene synthesis. This pathway converts isopentenyl pyrophosphate (IPP) into geranyl pyrophosphate, which serves as the C10 building block for molecules like limonene, myrcene, and pinene. Breeders and researchers track this pathway because its activity directly influences the terpene profile—and thus the aromatic character—of a cultivar. Understanding GPPP flux helps explain why some genetic lines reliably produce bright citrus or pine notes, while others develop earthier, more complex terpene ratios.

Cannabis breeders select for lines showing robust GPPP pathway activity to stabilize desirable monoterpene-forward profiles. Manipulating this metabolic checkpoint through selective breeding can shift a cultivar's aromatic expression without direct gene editing.
