Abstract:
All isolates examined of the phytopathogenic fungus Leptosphaeria maculans that are aggressive to Brassica napus and Brassica rapa have a repetitive element, LMR1. Horizontal transfer of LMR1 to an isolate of a closely related species of Leptosphaeria correlates with the expansion of the host range of this isolate to include Brassica juncea.
