Genetics behind deadly oat blight — ScienceDaily

A multi-institution team co-led by a Cornell University researcher has identified the genetic mechanisms that enable the production of a deadly toxin called Victorin — the causal agent for Victoria blight of oats, a disease that wiped out oat crops in the U.S. in the 1940s. Victoria blight is caused by the fungus Cochliobolus victoriae, […]
