New research reveals the disease that wiped out millions of potatoes and led to widespread famine in Ireland is still around, and it’s more virulent than ever.  A new study led by NC State University plant pathologist Jean Ristaino investigates the history of the fungus-like organism that caused the Irish potato famine and how its genome has evolved since it first showed up in Ireland in the 1800’s.
