Abstrakt: The nutritional integrity of wheat is jeopardized by rapidly rising atmospheric carbon dioxide (CO 2 ) and the associated emergence and enhanced virulence of plant pathogens. To evaluate how disease resistance traits may impact wheat climate resilience, 15 wheat cultivars with varying levels of resistance to Fusarium Head Blight (FHB) were grown at ambient and elevated CO 2 . Although all wheat cultivars had increased yield when grown at elevated CO 2 , the nutritional contents of FHB moderately resistant (MR) cultivars were impacted more than susceptible cultivars . At elevated CO 2 , the MR cultivars had more significant differences in plant growth, grain protein, starch, fructan, and macro and micro-nutrient content compared with susceptible wheat. Furthermore, changes in protein, starch, phosphorus, and magnesium content were correlated with the cultivar FHB resistance rating, with more FHB resistant cultivars having greater changes in nutrient content. This is the first report of a correlation between the degree of plant pathogen resistance and grain nutritional content loss in response to elevated CO 2 . Our results demonstrate the importance of identifying wheat cultivars that can maintain nutritional integrity and FHB resistance in future atmospheric CO 2 conditions.
