Nat Talk: The Wonderful Journey of the Cannabis Plant

On May 9, 2021

Humankind has been cultivating and breeding Cannabis (family Cannabaceae) for fiber, food, medicine, and intoxication for the last 10,000 years. But in the last 100 years, its legal status has led to some drastic changes at a genetic level.

Those changes include an extraordinary acceleration in new high Tetrahydrocannabinol (THC) and Cannabidiol (CBD) varieties. Dr. Todd Michael is a research professor in the Plant Molecular and Cellular Biology Laboratory at the Salk Institute. Leveraging cutting-edge genome mapping technology, he and his team have traced the origin and mechanism of high THC and CBD in the cultivars found in the United States today. Curiously, the results also reveal a tie to an ancient example of a naturally genetically modified organism (GMO).
