(Schematic cross-section showing leaf stomatal O_3 uptake, chloroplast oxidative stress, and the resulting downregulation of Earth’s global photosynthetic carbon uptake (GPP)) We usually think of ozone as a shield high in the atmosphere or as an air pollutant that harms human lungs near the ground. But plants also “breathe” ozone. Through microscopic pores called stomata, leaves take in carb ...[Read More]
