Caption: 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.
