A radical plan to preserve the beloved elm
A radical plan to preserve the beloved elm A project to breed an elm tree that is naturally
resistant to Dutch elm disease has begun at the University of
Guelph's Arboretum. Dutch elm disease is a fungus which is carried
from tree to tree by the bark beetle, and is deadly to elms. The
researchers hope that they can develop trees which can naturally
produce high enough levels of anti-fungal compounds called
phytoalexins that they can survive the disease. The project is
expected to take about thirty years. 9 APRIL 1999
