Cbd Synthase

CBD synthase is an enzyme that catalyzes the conversion of cannabidiolic acid (CBDA) to cannabidiol (CBD) through a decarboxylation process. This enzymatic pathway is fundamental to understanding cannabinoid biosynthesis in cannabis plants. Strains with active CBD synthase expression commonly produce elevated CBD levels relative to THC, a trait controlled by genetic variants in the relevant synthase genes. Breeders working with CBD-dominant cultivars focus on preserving and selecting for robust CBD synthase activity, as this enzymatic capacity directly influences the cannabinoid ratio expressed in the final plant material.

CBD synthase activity is a key target in breeding programs developing high-CBD, low-THC cultivars for research and regulated markets. Understanding synthase expression patterns helps breeders predict cannabinoid profiles across generations and stabilize desirable chemotypes.
