Data on contrasting sensitivities to seasonal warming among co-occurring diseases

The included data provide observational and experimental information on the temperature sensitivities of the fungal pathogens, Microbotryum silenes-inflatae (anther smut) and Thecaphora melandrii (receptacle smut), when affecting the host plant, Silene vulgaris. The data show counts of plants observed in natural populations of numbers of plants that displayed the smut diseases caused by the two fungi or were healthy, recorded in spring, summer or fall seasons. Also included are data on the disease symptoms of infected plants experimentally exposed to summer-time temperatures, data on disease symptoms of plants inoculated in the field under summertime temperatures, and data on disease symptoms of plants inoculated under growth chamber conditions matching summertime or spring/fall temperatures. The data can be used in manners that comply with a CC0 license waiver, including to distribute, remix, adapt, and build upon the material in any medium or format, with no conditions. There were no legal or ethical considerations related to the data collection.

Methods
Seasonal field surveys in natural populations indicate the numbers of plants of the status of showing the smut diseases caused by the two fungi or were healthy with 100-sequare-meter plots, recorded in spring, summer or fall seasons. Data on infected plants showing disease symptoms experimentally exposed to summer-time temperatures included pairs of M. silenes-inflatae and T. melanrdii pathogens at 3 to 30 days of exposure to the temperatures and replicated in two blocks. Among all these plants, all produced flowers were assessed for symptoms and counted as healthy or diseased. For data on plants inoculated under field conditions, either as M. silenes-inflatae (M) or T. melandrii (T) or a mixture of the two fungi, those showing symptoms of the two diseased or remaining healthy were counted. For data on plants inoculated under growth chamber conditions of spring/fall or summertime temperatures with either of the two pathogens, the numbers showing disease symptoms or remained healthy were counted.
