Relationship and genetic structure among autoecious and heteroecious populations of Cronartium pini in northern Fennoscandia
Epidemics of Scots pine blister rust, caused by Cronartium pini, have become an increasing problem in northern Finland and Sweden. The biology of the rust fungus is complex, with two different life cycle forms that cannot be morphologically distinguished, and it is unclear to what extent the two for...
