Impact of high atmospheric carbon dioxide on the biotic stress response of the model cereal species Brachypodium distachyon.

ABSTRACT: Losses due to disease and climate change are among the most important issues currently facing crop production. It is therefore important to establish the impact of climate change, and particularly of high carbon dioxide (hCO₂), on plant immunity in cereals, which provide 60% of human calories. The aim of this study was to determine if hCO₂ impacts Brachypodium distachyon immunity, a model plant for temperate cereals. Plants were grown in air (430 ppm CO₂) and at two high CO₂ conditions, one that is relevant to projections within the coming century (1000 ppm) and a concentration sufficient to saturate photosynthesis (3000 ppm). The following measurements were performed: phenotyping and growth, salicylic acid contents, pathogen resistance te
