Uncovering the mystery of a major threat to wheat
Date:6/1/2010

hat the stem rust pathogen had overcome the resistance commonly found in U.S. varieties of barberry.

Instead, they found barberry serving as a sexual or "alternate" host for stripe rust. When the overwintering spores of the stripe rust fungus germinate in the spring, they produce spores that reach barberry leaves, forming structures on the top of the leaves that allow mating between races or strains of the fungus. Spores resulting from this mating can, in turn, infect wheat.
