Scientists clone ‘survivor’ American elm trees

Scientists at a Canadian univeristy have found a way to successfully clone American elm trees that survived epidemics of Dutch elm disease. Using tissue samples collected from shoot tips and dormant buds, researchers at the University of Guelph in Canada employed in vitro technology to produce genetic copies of trees that survived multiple Dutch elm disease outbreaks.
