Between 750,000 and 1 million Irish died during the potato famine in the mid-19th century. Now, for the first time, scientists have sequenced the genome, or genetic script, of the pathogen that caused such devastation.

Reporting in the journal eLife, molecular biologists from the U.S. and Europe said they were able to put together the genetic script of the potato blight using dried potato specimens collected during the famine and preserved.
