“…The increasing ozone concentration contributes to a decline in forestry productivity linked to economic losses (Felzer et al, 2007;Percy and Karnosky, 2007;Pye, 1988). A variety of detrimental changes at the biochemical, physiological and molecular levels have been demonstrated in conifers and deciduous trees (Koch et al, 1998;Kopper and Lindroth, 2003;Richet et al, 2011Richet et al, , 2012Zhang et al, 2014a). Experimental evidence indicates that not only species but also cultivars, genotypes and clones, show different sensitivity to O 3 (Calatayud et al, 2011;Castagna et al, 2015;Dumont et al, 2014;H€ aiki€ o, 2009;Paoletti and Grulke, 2010;Zhang et al, 2012Zhang et al, , 2014c.…”

a b s t r a c tConcentration-and flux-based O 3 doseeresponse relationships were developed for poplars in China. Stomatal conductance (g s ) of five poplar clones was measured to parameterize a Jarvis-type multiplicative g s model. The maximum g s and other model parameters varied between clones. The strongest relationship between stomatal O 3 flux and total biomass was obtained when phytotoxic ozone dose (POD) was integrated using an uptake rate threshold of 7 nmol m À2 s À1 . The R 2 value was similar between flux-based and concentration-based doseeresponse relationships. Ozone concentrations above 28 e36 nmol mol À1 contributed to reducing the biomass production of poplar. Critical levels of AOT 40 (accumulated O 3 exposure over 40 nmol mol À1 ) and POD 7 in relation to 5% reduction in total biomass for poplar were 12 mmol mol À1 h and 3.8 mmol m À2 , respectively.

“…Indicatively, O 3 -induced alterations have been reported as phenological (Augustaitis and Bytnerowicz, 2008;Bortier et al, 2000;El-Khatib, 2003), physiological (Hoshika et al, 2013a;Paoletti et al, 2008;Scebba et al, 2006a;Street et al, 2011;Zhang et al, 2001Zhang et al, , 2014, transcriptional (Street et al, 2011), biochemical (Paoletti et al, 2008;Watanabe et al, 2013;Zhang et al, 2001), and genetic (Kolliker et al, 2008;Muller et al, 1996;Olbrich et al, 2010;Street et al, 2011) variables. Evidence also shows that Ο 3 impact on plants is not only direct, but also indirect as, for example, in the case of annual carbon absorption that has been reported to be negatively affected by Ο 3 (Watanabe et al, , 2014.…”

“…The response of these functions to O 3 could be either a direct effect of O 3 or a defensive mechanism of plants to O 3 . Stomatal conductance is considered an important factor in controlling the uptake of O 3 by plants and thus has been extensively studied (Hoshika et al, 2012a(Hoshika et al, , 2012bKitao et al, 2009;Madkour and Laurence, 2002;Moraes et al, 2006;Novak et al, 2005;Oksanen and Holopainen, 2001;Paoletti et al, 2008Paoletti et al, , 2010Pearson and Mansfield, 1993;Reiner et al, 1996;Samuelson, 1994;Zhang et al, 2001Zhang et al, , 2010Zhang et al, , 2014. Other features of wild plants that have been reported to be negatively influenced by O 3 include: (a) maximum net carbon uptake at light and CO 2 saturation (P max : Handley and Grulke, 2008), (b) maximum rate of electron transport (J max : Hoshika et al, 2013a;Paoletti et al, 2010), (c) light-saturated photosynthesis (A max : Hoshika et al, 2012a: Hoshika et al, , 2013aPaoletti et al, 2008Paoletti et al, , 2010Zhang et al, 2014), (d) CO 2 assimilation rate (P net : Madkour and Laurence, 2002;Moraes et al, 2006;Torre et al, 1998), (e) net carbon assimilation rate at light saturation (A sat : Moraes et al, 2006;Zhang et al, 2014), (f) water use efficiency (Hoshika et al, 2012b), (g) actual photochemical efficiency of PSII in the saturated light (F v /F m ratio: Moraes et al, 2006;Paoletti et al, 2010;Zhang et al, 2014), and (i) steady-state leaf gas exchange (Hoshika et al, 2012a).…”

Ambient ozone (O 3 ) poses a growing threat to the global ecosystems due to its high phytotoxicity: it may possibly reduce the productivity of wild plants as well as the species' biodiversity. Asia hosts a remarkable number of wild plant species; thus, studies dealing with Asian species' responses to O 3 are of great importance. We have retrieved, from scientific databases, 195 papers dealing with the response of 473 wild plants species to O 3 . Some species we characterize as "ozonophobic" have been reported to be negatively affected by O 3 , even at O 3 levels lower than the AOT40 threshold. This review revealed the lack of research dealing with the effects of O 3 on endangered or threatened plant species, as well as on important medical plants. Such research is needed not only from an ecological point of view or in terms of biodiversity value, but also from an anthropocentric point of view. Several wild species carry unique substances that are used in medicines for healing human diseases or in agro-industry for the production of agrochemicals, thus securing human welfare.

“…The detrimental effects of O 3 on potential photosystem II (PSII) photochemical efficiency (F v /F m ), actual photochemical efficiency of PSII in the saturated light (F v '/F m '), light-adapted apparent quantum efficiency of PSII ( PSII ) and the percentage of open photosynthetic reaction centers (qP) have been widely reported (e.g. Feng et al, 2011b;Pellegrini, 2014;Zhang et al, 2014), suggesting that photochemistry was depressed and the production of NADPH and ATP for CO 2 reduction may be decreased. A reduction of maximum rate of RuBisCo-limited carboxylation (V cmax ) has also been considered a main factor being responsible for impairment of photosynthesis (Matyssek et al, 1991;Zheng et al, 2002;Morgan et al, 2004;Fiscus et al, 2005;Pellegrini et al, 2011).…”

a b s t r a c tUrban green spaces (UGS) offer several ecosystemical benefits to the urban environment. However, these advantages may be weakened by alterations of plants photophysiological mechanisms due to increasing tropospheric ozone (O 3 ) concentrations, a serious problem for China. To evaluate their utilization in UGS, we selected three widely-used urban plant species (smoke tree, Cotinus coggygria Scop.; marigold, Tagetes erecta Linn.; rose, Rosa chinensis Jacp.) to investigate their biometric and photophysiological responses to (i) ambient air (AA), (ii) AA + 60 ppb O 3 (AA + 60), and (iii) AA + 120 ppb O 3 (AA + 120) (9 h d −1 , from 8:30 am to 5:30 pm). Considering visible injury and biomass production, smoke tree and marigold seem to be O 3 -sensitive, whereas rose should be considered more tolerant. The exposure to the pollutant gas reduced photosynthetic efficiency in all seedlings. However, different features were shown throughout our study by the three species here monitored. In smoke tree, stomatal limitations seemed to be its principal weakness. In marigold, the reduction of the photosynthetic performance was mainly ascribable to impairments of both light and dark reactions of photosynthesis. Here, stomatal closure maybe not the cause to limit the photosynthetic rate, but a down-regulated response. Unexpectedly, CO 2 assimilation increased in roses exposed to AA + 60 and did not change in those treated with AA + 120 after one month from the beginning of the exposure (FBE). This seemed due to a better efficacy of these plants in dark reactions of photosynthesis. This feature was confirmed also a month later. In conclusion, the results of this study indicate that non-invasive methods such as gas exchange and chlorophyll fluorescence for monitoring photosynthetic performance of urban plants can be useful to give guidelines to manage UGS in the "climate change era". Generally, in severe O 3 -polluted areas as those of several cities of China, the plants with high-efficient biochemical processes driving a well photosynthetic performance (such as rose) might be a recommended choice. © 2016 Elsevier GmbH.
