| Summary: | Cold-adapted organisms with current arctic-alpine distributions have persisted during the last glaciation in multiple ice-free refugia, leaving footprints in their population structure that contrast with temperate plants and animals. However, pathogens that live within hosts having arctic-alpine distributions have been little studied. Here, we therefore investigated the geographical range and population structure of a fungus parasitizing an arctic-alpine plant. A total of 1437 herbarium specimens of the plant Silene acaulis were examined, and the anther smut pathogen Microbotryum silenes-acaulis was present throughout the host’s geographic range. There was significantly greater incidence of anther smut disease in more northern latitudes and where the host locations were less dense, indicating a major influence of environmental factors and/or host demographic structure on the pathogen distribution. Genetic analyses with seven microsatellite markers on recent collections of 195 M. silenes-acaulis individuals ... : Herbaria-CollectionsResults from herbaria collection of specimens of the plant Silene acaulis partially infected with the pathogen Microbotryum silenes-acaulis. Data has been recorded between 2001 to 2013 from the following herbaria: U.S. Forest Service Herbarium (USFS), New York Botanical Garden (NY), Museum National d'Histoire Naturelle (P), Oregon State University (OSC), University of California, Berkeley (UC), University of Iowa and Iowa State University (ISC), University of Minnesota (MIN), University Washington (WTU), Washington State University (WS), British Museum of Natural History (BM).Microsatellite-DataMicrosatellite data file resulting from genotyping of 255 individuals of Microbotryum silenes-acaulis with 23 markers. Second sheet represents the Structure Input File for the global data set (195 Individuals) analysed with 16 previously developed markers. Third sheet represents the Structure Input File for the Norway/Svalbard Set (110 Individuals) analysed with seven newly-developed markers. ... |
