Potato plants exposed to the pathogen that causes late blight, the disease
responsible for the Irish potato famine, soon wither and die (left). The
plant on the right has been engineered to resist the devastating disease
through incorporation of a gene found in a wild Mexican potato, as part
of research by John Helgeson, professor of plant pathology and Jiming Jiang,
professor of horticulture and others.
