Technical Abstract: Rising carbon dioxide (CO2) can change the nutritional content of wheat and increase the severity of Fusarium head blight (FHB), a devastating fungal disease of wheat that reduces yield and contaminates grain with harmful mycotoxins. At elevated CO2, FHB susceptible and moderately resistant wheat had disproportionate losses in protein and mineral content, with moderately resistant cultivars more severely impacted. Furthermore, on the grain with the most severe loss of nutritional content some Fusarium graminearum strains increased production of the mycotoxin deoxynivalenol. Future climate conditions may provide a pathogenic advantage on hosts with lower nutritional content, threatening global food safety and security. Wheat growers may be less likely to choose moderately resistant cultivars with reduced end use quality. Therefore, FHB control strategies should consider the climate resilience of wheat nutritional content.
