Summary

Tropospheric ozone (O3) is now considered as the most widespread and toxic gaseous pollutant in our environment. To date, unsustainable resource utilization has turned this secondary pollutant into a major component of global climate change, and a prime threat to agricultural production. The projected levels to which O3 will increase are critically alarming, and have become a major issue of concern for global food production. Plants are “soft targets” for O3. Ozone enters plants through stomata, where it can be dissolved in the apoplastic fluid. Ozone has several potential effects on plants: direct reaction with cell membranes; generation of ROS and H2O2 (which alters cellular function by causing cell death); induction of premature senescence; and up- or down-regulation of responsive components such as genes, proteins, and metabolites. In this chapter, we make an attempt to present an overview picture of agricultural crops and O3 interactions. We summarize the vast number of available reports on plant responses to O3 at the morphological, physiological, cellular, and biochemical levels, and also address effects on crop yield, and on “-omics” level.
