Arabidopsis wound-induced gene expression at elevated CO2
Increasing atmospheric CO2 levels are expected to decrease jasmonate-mediated defenses in C3 plants, increasing their susceptibility to chewing herbivores and necrotrophic pathogens. The aim of this project was to understand how elevated CO2 impacts wound-responsive gene expression in Arabidopsis thaliana and to investigate the role of CYP20-3 in regulating jasmonate biosynthesis at eCO2. Wildtype and cyp20-3 knockout arabidopsis were grown at ambient (450 ppm) or elevated (900 ppm) CO2. Undamaged and mechanically wounded plants were harvested for transcriptomic analysis.
