“…An effective method to reduce yield loss could be to breed O 3 -resistant genotypes by adding the O 3 -resistant genes using modern molecular biology techniques. Some genes conferring O 3 -resistance have been determined in rice and soybean (Frei et al, 2010;Frei, 2015;Gillespie et al, 2011).…”

“…Rice (Oryza sativa) is the major staple crop throughout Asia, and it is strongly affected by tropospheric ozone because its cropping season overlaps with peak ozone concentrations, especially in South and East Asia (Frei, 2015). Previous studies estimated around 3.7% of global rice yield loss and regionally more than 10% of rice yield loss due to elevated tropospheric ozone, and this trend will exacerbate in the future with increasing concentrations (Ainsworth, 2008;Van Dingenen et al, 2009).…”

“…A number of previous studies have determined genetic factors associated with ozone tolerance in rice, suggesting that this trait is controlled by multiple medium-effect loci rather than a single large-effect locus (Frei, 2015;Ueda et al, 2015). In a study by Frei et al (2008), several ozone-related quantitative trait loci (QTLs) were identified using a mapping population derived from the contrasting cultivars Nipponbare (susceptible) and Kasalath (tolerant).…”

“…However, the genetic basis for the differential sensitivity remains elusive, although some recent studies with O 3 ‐sensitive and O 3 ‐resistant Arabadopsis thaliana (Xu et al., 2015) and crops such as rice (Frei, 2015) have identified multiple qualitative trait loci potentially involved in regulating the O 3 response. Furthermore, and in contrast to many other environmental stresses, there is a limited functional pattern to O 3 sensitivity.…”

Risks associated with exposure of individual plant species to ozone (O3) are well documented, but implications for terrestrial biodiversity and ecosystem processes have received insufficient attention. This is an important gap because feedbacks to the atmosphere may change as future O3 levels increase or decrease, depending on air quality and climate policies. Global simulation of O3 using the Community Earth System Model (CESM) revealed that in 2000, about 40% of the Global 200 terrestrial ecoregions (ER) were exposed to O3 above thresholds for ecological risks, with highest exposures in North America and Southern Europe, where there is field evidence of adverse effects of O3, and in central Asia. Experimental studies show that O3 can adversely affect the growth and flowering of plants and alter species composition and richness, although some communities can be resilient. Additional effects include changes in water flux regulation, pollination efficiency, and plant pathogen development. Recent research is unraveling a range of effects belowground, including changes in soil invertebrates, plant litter quantity and quality, decomposition, and nutrient cycling and carbon pools. Changes are likely slow and may take decades to become detectable. CESM simulations for 2050 show that O3 exposure under emission scenario RCP8.5 increases in all major biomes and that policies represented in scenario RCP4.5 do not lead to a general reduction in O3 risks; rather, 50% of ERs still show an increase in exposure. Although a conceptual model is lacking to extrapolate documented effects to ERs with limited or no local information, and there is uncertainty about interactions with nitrogen input and climate change, the analysis suggests that in many ERs, O3 risks will persist for biodiversity at different trophic levels, and for a range of ecosystem processes and feedbacks, which deserves more attention when assessing ecological implications of future atmospheric pollution and climate change.
