“…Simultaneous stresses of pathogen infection and elevated O 3 may result in altered host immune response on the resistant cultivar. Oxidative damage of the plant cuticle caused by elevated [O 3 ] can increase exposure to pathogens, thus, impacting disease severity [ 99 ]. Complementing this current study with host transcriptomics will explain if such host defense alteration may be what explains the increased susceptibility on resistant cultivar in presence of elevated O 3 .…”

“…Specifically, previous work has shown that plants grown under abiotic stress conditions show increased disease susceptibility due to induction of the abscisic acid (ABA) pathway, which antagonizes the salicylic acid (SA) pathway involved in pathogen defense (63,64). Moreover, the oxidative damage of the plant cuticle caused by elevated [O 3 ] might leave plants more exposed to pathogens, thus increasing disease severity (65). Higher disease severity in plants exposed to pathogens was also seen in O 3 tolerant tomato (66) and spot blotch fungus in barley (67).…”

“…It has been reported that many abiotic stress conditions may weaken the defense mechanisms of plants and enhance their susceptibility to pathogenic infection ( Atkinson and Urwin, 2012 ). Berner et al. (2015) observed that though the economic yield was not affected under CO 2 and O 3 interaction in brassica, however, the plants became more susceptible to pathogen and insect attack.…”

“…(2020) there is a need to quantify the O 3 impacts on crops along with other environmental stresses. Higher O 3 levels may increase the plant's susceptibility by seriously damaging the cuticle layer of the plants, leaving them exposed to pathogen and insect attack ( Berner et al., 2015 ) and increase in plant diseases. Exposure to elevated O 3 doesn't have any direct effect on fungal pathogens, but may increase the tendency of necrotrophic pathogens to colonize plants weakened by O 3 ( Manning and Tiedemann, 1995 ).…”
