“…The decrease in Rubisco protein subunits could be interpreted from damage by ROS to chloroplasts and photosynthetic electron transport (under publication). In contrast to the results from Eckardt and Pell (1994) who found that LSU was less responsive to ozone than SSU in Solanum tuberosum but matching previous results gained from Phaseolus vulgaris (Junqua et al 2000) and Zea mays (Leitao et al 2007), we showed that both subunits of Rubisco in rice cultivars were equally reduced by an ozone dose. Such similar reductions might reflect distinct ozone impact.…”

This study evaluates the influences of nickel and ozone exposure individually and/ or in combination on growth performance, antioxidant activity and genes up regulation of two rice cultivars Sakha 101 and Giza 178. Ni treatment at high doses (100 µM Ni) and 75 ppb O 3 alone reduced the fresh weight, mineral content, membrane integrity and Rubisco content. There was an increase in SOD and APX activity in the shoots of rice cultivars, whereas, there was a decrease in GR and GST in the roots and shoots. In contrast combined stresses appeared to be stimulatory for growth and mineral contents, Rubisco content and antioxidant enzymes. Nonspecific lipid transfer protein and transmembrane protein genes were up regulation in rice cultivars in response to Ni stress. Carotenoid cleavage dioxygenase is upregulated in response to ozone stress; RNA pseudouridine synthase, heat shock proteins and cytochrome P450-like were upregulated in response to combined stresses. The results revealed that the interactive effects of both stresses were antagonistic on growth parameters and antioxidant activities to overcome the adverse effects of both pollutants.

“…For these two parameters, O 3 exposure had the same effect or nearly the same effect on the two genotypes depending on sampling times. The reduction in Rubisco content and activity has been recorded in leaves of many species undergoing an oxidative stress and has been linked to several mechanisms such as (1) an increase in its proteolysis (Peñarrubia and Moreno ), (2) protein and/or mRNA synthesis inhibition (Brendley and Pell , Pelloux et al , Bohler et al ) and (3) protein fragmentation or structure modification due to ROS production (Ishida et al , Pell et al , Junqua et al , Abat et al ). An increase in PEPC activity was distinctly observed for the two genotypes; that kind of O 3 ‐induced effect has been previously mentioned for poplar trees (Landolt et al , Dizengremel ).…”

Cell capacity for cytosolic NADPH regeneration by NADP-dehydrogenases was investigated in the leaves of two hybrid poplar (Populus deltoides × Populus nigra) genotypes in response to ozone (O3 ) treatment (120 ppb for 17 days). Two genotypes with differential O3 sensitivity were selected, based on visual symptoms and fallen leaves: Robusta (sensitive) and Carpaccio (tolerant). The estimated O3 flux (POD0 ), that entered the leaves, was similar for the two genotypes throughout the treatment. In response to that foliar O3 flux, CO2 assimilation was inhibited to the same extent for the two genotypes, which could be explained by a decrease in Rubisco (EC 4.1.1.39) activity. Conversely, an increase in PEPC (EC 4.1.1.31) activity was observed, together with the activation of certain cytosolic NADP-dehydrogenases above their constitutive level, i.e. NADP-G6PDH (EC 1.1.1.49), NADP-ME (malic enzyme) (EC 1.1.1.40) and NADP-ICDH (NADP-isocitrate dehydrogenase) (EC1.1.1.42). However, the activity of non-phosphorylating NADP-GAPDH (EC 1.2.1.9) remained unchanged. From the 11th fumigation day, NADP-G6PDH and NADP-ME profiles made it possible to differentiate between the two genotypes, with a higher activity in Carpaccio than in Robusta. At the same time, Carpaccio was able to maintain high levels of NADPH in the cells, while NADPH levels decreased in Robusta O3 -treated leaves. All these results support the hypothesis that the capacity for cells to regenerate the reducing power, especially the cytosolic NADPH pool, contributes to improve tolerance to high ozone exposure.

“…The last atmosphere was an unchambered ambient air control (AA), in order to monitor possible OTC effects. Complete descriptions of OTCs, technical characteristics of the fumigation system, and recording of ozone data are detailed elsewhere (Junqua et al, 2000). Extra ozone was added to non-filtered air (NF) from 10:00 to 17:00 h Greenwich mean time (GMT) in order to simulate the normal period of ozone exposure.…”

The Impact of Ozone on Juvenile Maize (Zea mays L.) Plant Photosynthesis: Effects on Vegetative Biomass, Pigmentation, and Carboxylases (PEPc and Rubisco)

The impact of ozone on crops was more studied in C (3) than in C (4) species. In C (3) plants, ozone is known to induce a photosynthesis impairment that can result in significant depressions in biomass and crop yields. To investigate the impact of O (3) on C (4) plant species, maize seedlings ( ZEA MAYS L. cv. Chambord) were exposed to 5 atmospheres in open-top chambers: non-filtered air (NF, 48 nL L (-1) O (3)) and NF supplied with 20 (+ 20), 40 (+ 40), 60 (+ 60), and 80 (+ 80) nL L (-1) ozone. An unchambered plot was also available. Leaf area, vegetative biomass, and leaf dry mass per unit leaf area (LMA) were evaluated 33 days after seedling emergence in OTCs. At the same time, photosynthetic pigments as well as carboxylase (PEPc and Rubisco) activities and amounts were also examined in the 5th leaf. Ozone enhanced visible symptoms characterizing foliar senescence. Across NF, + 20, + 40, and + 60 atmospheres, both chlorophylls and carotenoids were found to be linearly decreased against increasing AOT40 ( CA. - 50 % in + 60). No supplementary decrease was observed between + 60 and + 80. Total above-ground biomass was reduced by 26 % in + 80 atmosphere; leaf dry matter being more depressed by ozone than leaf area. In some cases, LMA index was consistent to reflect low negative effects caused by a moderate increase in ozone concentration. PEPc and Rubisco were less sensitive to ozone than pigments: only the two highest external ozone doses reduced their activities by about 20 - 30 %. These changes might be connected to losses in PEPc and Rubisco proteins that were decreased by about one-third. The underlying mechanisms for these results were discussed with special reference to C (3) species. To conclude, we showed that both light and dark reactions of C (4) photosynthesis can be impaired by realistic ozone doses.
