Abstract

Atmospheric CO2 concentrations are predicted to double within the next century. Despite this trend, the extent and mechanisms through which elevated [CO2] affect plant diseases remain uncertain. Triticum aestivum (var. PBW 343) plants were exposed to two different CO2 concentrations (390/550 ppm) in free-air CO2 enrichment technology (FACE). Survey of Triticum aestivum for natural disease incidence revealed that elevated [CO2] increased yellow rust incidence. To assess the mechanisms underlying these changes, we conducted leaf structural,
