Ozone is an agricultural nuisance that routinely impacts citrus trees, yet our understanding of plant-ozone interactions remain limited due to the complexity of mechanisms behind these interactions. Uptake of ozone into plants is a key sink for ground-level ozone, but this uptake has consequences for both plant wellness and the emission of chemicals from plants. By closing the pores on their leaves, plants limit the uptake ozone at the cost of limiting uptake of carbon dioxide for photosynthesis. Plants can also release volatile chemicals to react with nearby ozone either as a defensive response or as a sign of damage. We share results from in-lab ozone fumigation experiments on Meyer lemon trees. We measured photosynthesis and chemical emissions over different concentrations and durations of ozone exposure. While tracking recovery, we found that lower concentrations of ozone led to stronger physiological suppression, whereas higher concentrations triggered more volatile emissions. These findings highlight how ozone exposure not only suppresses crop productivity but also shifts atmospheric chemistry, reinforcing the need to consider plant-atmosphere feedback both in agriculture and air quality models.
