“…However, several studies indicate that ROS may be important components of signal transduction pathways that influence plant defense responses and PCD for a wide variety of stimuli, including pathogens such as fungi, bacteria, and viruses (Lamb and Dixon 1997;Jabs 1999). The production of secondary ROS due to the O 3 degradation in the apoplast induces an endogenous, enzymatic ROS generation or "oxidative burst" similar to that seen in the HR-mediated cell death (Baier et al 2005) triggering a series of signaling cascades that work simultaneously, alternatively, or in series (Vaultier and Jolivet 2015) by amplifying the ROS wave in different subcellular compartments ( Fig. 9.1).…”

Among various contaminants, ozone (O 3 ) is considered the most ubiquitous and phytotoxic atmospheric pollutant in industrialized and developing countries. It causes extensive risks for plant life, in terms of survival and productivity of wild and cultivated species. Plant response to O 3 resembles the biotic defense reactions and includes two steps: the first is a biphasic oxidative burst with a massive, rapid, and transient increase in apoplastic reactive oxygen species (ROS) production; the second is the induction of the hypersensitive response (HR) and systemic acquired resistance (SAR). In particular, the acute O 3 exposure (high concentrations for a few hours) results in the activation of programmed cell death (PCD) response that interacts with the synthesis of several hormones and other signaling molecules. The cross talk among all these molecules and their complex and interconnected signaling pathways are more important to determine (1) the initiation, propagation, and containment of O 3 -induced cell death, (2) the degree of the sensitivity of plants to this contaminant, and (3) the regulatory potential that plants have to promptly respond to oxidative stress. The present chapter reviews the role of phytohormones (such as ethylene, abscisic acid, gibberellins, auxins, and cytokinins) and other signaling molecules (such as salicylic and jasmonic acids, proline, and brassinosteroids), as well as their synergistic and antagonistic effects, in the complex signaling pathway involved in plant responses to O 3 stress.

“…In order to elicit and decipher signalling processes, trees were exposed to acute O 3 dose (>150-200 ppb) for few hours. In these conditions, some signalling actors, as calcium or protein kinases, were well characterized in herbaceous plants (Baier et al 2005;Vainonen and Kangasjarvi 2014;Vaultier and Jolivet 2015). However, O 3 -induced signalling is by far less documented in trees.…”

Abstract& Key message Ozone, one of the major atmospheric pollutants, alters tree growth, mainly by decreasing carbon assimilation and allocation to stems and roots. To date, the mechanisms of O 3 impact at the cellular level have been investigated mainly on young trees grown in controlled or semi-controlled conditions. In the context of climate change, it is necessary to introduce a valuable defence parameter in the models that currently predict O 3 impact on mature trees and the carbon sequestration capacity of forest ecosystems.

“…Ozone was the most reactive air pollutant. Production of forests and cultivation of crops around the world, such as wheat, soybeans, rice and maize, were severely affected by high ozone concentration (Vaultier and Jolivet, 2015;Dingenen et al, 2009;Tai et al, 2014;Avnery et al, 2011). There have been several studies indicating that ozone could cause severe effects on plant physiology, for instance, the reduction of photosynthesis and visible injury due to changing of lipid metabolism, membrane permeability and nutrient leaching consequently decreasing the crop production (Feng et al, 2016;Sicard et al, 2016;Díaz-De-Quijano et al, 2012).…”

Generally, when ozone enters plant leaves through stomata, it would quickly filtrate and react with apoplastic fluid in cell membrane causing free radicals and other reactive oxygen species (ROS), which damages structure and function of cell membrane (Vaultier and Jolivet, 2015;Heath, 2008). Strong oxidants ROS that also act as signal molecules in plants would initiate hypersensitive responses (HR), including the activation ethylene, salicylic acid jasmonate and the programmed cell death in response to ozone (Kangasjärvi et al, 1994).…”

Ozone is the most oxidative air pollutant and considered as an abiotic stress which harm to vegetation and crop. Similarly, biological stressor such as plant pathogen could cause severe damage to crops. Combination effects from both stresses will potentially lead to economic loss. Basically, plants will response to both abiotic stress and pathogenic stressor by generate antioxidants and phytoalexins. The concentration of these chemical indicate stress level in plant and also defence system response. This research is aimed to investigate the combination effects of ozone and Xanthomonas oryzae pv. oryzae on antioxidants and phytoalexins in rice (Oryza sativa L. cv. KDML 105). In this study, 45-day-old rice plants were used. Ozone was elevated at concentrations of 100, 200 and 300 ppb in the fumigating chambers for 12 hours. Xanthomonas oryzae pv. oryzae which caused bacterial blight disease in rice was selected as plant pathogen. Combining effects of ozone and Xanthomonas oryzae pv. oryzae were examined using ozone at a concentration of 100 ppb and Xanthomonas oryzae pv. oryzae 1x10 8 cells/ml inoculation. The experimental design was a completely randomized design with 2×2 factorials treatment and three replications required. Temperature, relative humidity and light intensity in fumigating chambers were controlled. The results of the combining effects showed the amount of antioxidants and phytoalexins were higher than those in single treatment. The experimental data indicated that the combining effects will result in more stress in rice. This suggests that, in rice plantation area with experience of ozone episode, pathogenic resistance rice strain should be considered to reduce combining effects.
