Researchers identify genes that give cannabis its flavour
UBC scientists have scanned the genome of cannabis plants to find the genes responsible for giving various strains their lemony, skunky or earthy flavours, an important step for the budding legal cannabis industry.
“The goal is to develop well-defined and highly-reproducible cannabis varieties. This is similar to the wine industry, which depends on defined varieties such as chardonnay or merlot for high value products,” said Jörg Bohlmann, a professor in the Michael Smith Laboratories and faculty of forestry at UBC. “Our genomics work can inform breeders of commercial varieties which genes to pay attention to for specific flavour qualities.”
The research is part of an ongoing collaboration between Bohlmann, graduate student Judith Booth, and Jonathan Page, an adjunct professor in the botany department who founded the cannabis testing and biotechnology company Anandia Labs.
They found about 30 terpene synthase genes that contribute to diverse flavours in cannabis. This number is comparable to similar genes that play a role in grapevine flavour for the wine industry. The genes the researchers discovered play a role in producing natural products like limonene, myrcene, and pinene in the cannabis plants. These fragrant molecules are generally known in the industry as terpenes.
