(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, …[Read More]
