Seeds of Silene vulgaris were sampled from natural populations as 28 maternal half-sib families (seeds from a single maternal plant, but where multiple sires are possible), with two families from each of 14 localities. The seed families were used for inoculation experiments, testing the relationship between infection rates (proportions that became diseased following exposure to the pathogen) for an endemic pathogen of S. vulgaris (the anther-smut pathogen Microbotryum silenes-inflatae) and a foreign pathogen (anther-smut pathogen Microbotryum lychnidis-dioicae that normally occurs on a different host, Silene latifolia) and a foreign necrotrophic pathogen (Stemphylium solani). The endemic pathogen, M. silenes-inflatae, was collected as the spore contents of a diseased S. vulgaris flower from one of the populations (coordinates, 44.212, 7.672). The foreign pathogen, M. lychnidis-dioicae, was collected from a diseased S. latifolia plant in Lamole, Italy (coordinates, 43.551, 11.358). The necrotrophic foliar pathogen, Stemphylium solani, was isolated from an S. vulgaris plant in the introduced range in Bernardston, MA (coordinates, 42.682, -72.544) and cultured on malt extract agar. Its identity was confirmed by the DNA sequence of the internal transcribed spacer region of the ribosomal RNA (GenBank accession MN856663). Data show the locations of the seed collections and the proportions of plants that became diseased following exposure to the pathogen or lesion size (cm2), also showing sample sizes.
