Sammanfattning

Patterns of colonization of conifer roots by dark septate endopyhtes of the Phialocephala fortinii s. lat. species complex in nurseries in Switzerland and Lithuania were studied. The potential for man-mediated genotype flow was estimated for two Swiss nurseries based on customers' addresses and the number of delivered plants. Two hundred and forty-nine strains from three Swiss and five Lithuanian nurseries and an afforestation site were characterized using a combination of inter-simple sequence repeat-anchored PCR (ISSR-PCR), single-copy RFLP analysis, and sequence analysis. P. fortinii s. lat. was abundant in nursery seedlings, but the frequency of seedlings colonized varied considerably among and within nurseries. Ten cryptic species (CSP) of P. fortinii s. lat. were identified, including four hitherto undiscovered CSP. P. helvetica was the dominant species in Swiss nurseries, whereas P. fortinii s. str. was the most abundant species in Lithuanian nurseries and the afforestation site. Swiss nurseries deliver plants over distances of more than 200 km indicating the high potential for man-mediated genotype flow in P. fortinii s. lat. (C) 2008 The British Mycological Society.
