Contributor to the Human Genome Project and cannabis viral expert
Kevin McKernan debuts on the show for a DEEP DIVE into viral
cannabis pathogens! Kevin starts by breaking down the science of
what a viroid is, how it differs from a virus, and what it's role
in the natural world is. He discusses hop latent viroid in
cannabis, and explains the mechanisms by which it replicates itself
using the plant's energy, and stops the expression of desirable
traits like potency, terpene expression, and more. This leads to a
conversation about the hops industry, where instead they opted to
breed cultivars that would carry the virus but resist it- as
opposed to the cannabis approach of testing for viruses and culling
any positives. Kevin wraps up the show by talking about tobacco
mosaic virus, why it's so misdiagnosed, and just how many varieties
there are of these types of plant virals...
