Molecular characterisation of Sawadaea anamorphs in Australia.
To identify the species of Sawadaea in Australia from anamorphic material, the ribosomal DNA internal transcribed spacer region was amplified from a range of specimens (from the Australian Capital Territory, Victoria, Tasmania and New South Wales) and subjected to restriction fragment length polymorphism (RFLP) analysis. Specimens of known species were included for comparison. RFLP analysis revealed S. bicornis was found on Acer negundo, A. rubrum and A. pseudoplatanus, while S. polyfida var. japonica was found on A. japonicum and A. palmatum. This is the first record of S. polyfida var. japonica on A. japonicum. These results agree with reported host ranges for both species in Europe and Asia.
