Here I explored the effects of fungicide exposure on endophyte diversity in an experimental prairie, the Philips Tract, and tested the effects of soil fertilizers on the relationship between endophytes and their hosts. To measure fungicide effects on fungal diversity, fungal isolates were cultured and fungal DNA was sequenced from leaves of Andropogon gerardii, Sorghastrum nutans, Monarda fistulosa, Penstemon digitalis, and Pycnanthemum virginianum from control and fungicide-treated plots. Additionally, isolated fungi were screened for auxin and ammonia production and phosphate solubilization ability to determine potential plant growth-promoting phenotypes. To test the effects of fertilizers on these plant-fungal interactions, greenhouse plants were inoculated with fungal isolates and grown under control and fertilized soil conditions. Results from this study found that S. nutans had a significant decrease in fungal richness in fungicide-treated plots, fungicide did not affect fungal composition, two isolates produce auxin, all isolates produce ammonia, no isolate could solubilize phosphate, and that an Alternaria sp., Nemania sp., Hypoxylon sp., and Phoma sp. significantly increased change in height of their respective plant hosts only in either control or fertilized conditions. This study has thus highlighted the potential impacts that neighboring agricultural activity may be having on aboveground plant-fungal relationships in nearby prairie systems."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Fungicide and fertilizer-mediated changes in prairie plant-foliar fungal endophyte interactions"]}]}],"canonical_facts":{"dc:contributor":["Yannarell, Anthony","Dalling, James","Heath, Katy"],"dc:creator":["Brown, Noah"],"dc:date":["2024-07-16","2024-08"],"dc:description":["Submission original under an indefinite embargo labeled 'Open Access'.
