An international research team has decoded the genome of the notorious organism that triggered the Irish potato famine in the mid-19th century and now threatens this season's tomato and potato crops across much of the US. The study reveals an unusually large genome size -- more than twice that of closely related species -- and an extraordinary genome structure, which together appear to enable the rapid evolution of genes, particularly those involved in plant infection.
