Mechanisms of glacial-to-future atmospheric CO₂ effects on plant immunity.

ABSTRACT: The impacts of rising atmospheric CO₂ concentrations on plant disease have received increasing attention, but with little consensus emerging on the direct mechanisms by which CO₂ shapes plant immunity. Furthermore, the impact of sub-ambient CO₂ concentrations, which plants have experienced repeatedly over the past 800 000 yr, has been largely overlooked. A combination of gene expression analysis, phenotypic characterisation of mutants and mass spectrometry-based metabolic profiling was used to determine development-independent effects of sub-ambient CO₂ (saCO₂ ) and elevated CO₂ (eCO₂ ) on Arabidopsis immunity. Resistance to the necrotrophic Plectosphaerella cucumerina (Pc) was repressed at saCO₂ and en
