To characterize the impact of ozone on the post-harvest performance of kiwifruit (<italic>Actinidia deliciosa</italic> cv. ‘Hayward’), fruits were cold stored (0 °C, 95% relative humidity) in a commercial ethylene-free room for 1, 3, or 5 months in the absence (control) or presence of ozone (0.3 μl l<sup>−1</sup>) and subsequently were allowed to ripen at a higher temperature (20 °C), herein defined as the shelf-life period, for up to 12 days. Ozone blocked ethylene production, delayed ripening, and stimulated antioxidant and anti-radical activities of fruits. Proteomic analysis using 1D-SDS-PAGE and mass spectrometry identified 102 kiwifruit proteins during ripening, which are mainly involved in energy, protein metabolism, defence, and cell structure. Ripening induced protein carbonylation in kiwifruit but this effect was depressed by ozone. A set of candidate kiwifruit proteins that are sensitive to carbonylation was also discovered. Overall, the present data indicate that ozone improved kiwifruit post-harvest behaviour, thus providing a first step towards understanding the active role of this molecule in fruit ripening.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name sortKey="Agrawal, Gk" uniqKey="Agrawal G">GK Agrawal</name></author><author><name sortKey="Job,

To characterize the impact of ozone on the post-harvest performance of kiwifruit (<italic>Actinidia deliciosa</italic> cv. ‘Hayward’), fruits were cold stored (0 °C, 95% relative humidity) in a commercial ethylene-free room for 1, 3, or 5 months in the absence (control) or presence of ozone (0.3 μl l<sup>−1</sup>) and subsequently were allowed to ripen at a higher temperature (20 °C), herein defined as the shelf-life period, for up to 12 days. Ozone blocked ethylene production, delayed ripening, and stimulated antioxidant and anti-radical activities of fruits. Proteomic analysis using 1D-SDS-PAGE and mass spectrometry identified 102 kiwifruit proteins during ripening, which are mainly involved in energy, protein metabolism, defence, and cell structure. Ripening induced protein carbonylation in kiwifruit but this effect was depressed by ozone. A set of candidate kiwifruit proteins that are sensitive to carbonylation was also discovered. Overall, the present data indicate that ozone improved kiwifruit post-harvest behaviour, thus providing a first step towards understanding the active role of this molecule in fruit ripening.</p></abstract><kwd-group><kwd><italic>Actinidia deliciosa</italic></kwd><kwd>antioxidants</kwd><kwd>anti-radical activity</kwd><kwd>ethylene</kwd><kwd>ozone</kwd><kwd>post-harvest storage</kwd><kwd>protein carbonylation</kwd></kwd-group><counts><page-count count="16"></page-count></counts></article-meta></front><body><sec><title>Introduction</title><p>Fruit ripening is a complex, genetically programmed senescence process, and its elucidation relies more on a holistic than on a single process study approach (<xref ref-type="bibr" rid="bib63">Ramina <italic>et al.</italic>, 2008</xref>). Fleshy fruits have been classified as climacteric or non-climacteric, depending on whether or not a fruit exhibits a peak in respiration and ethylene production during ripening (<xref ref-type="bibr" rid="bib28">Giovannoni, 2004</xref>). The major area of ripening research involves the post-harvest management, since horticultural industry faces huge economic losses every year as a result of ethylene-induced senescence (<xref ref-type="bibr" rid="bib45">Martínez-Romero <italic>et al.</italic>, 2007</xref>). Therefore, understanding the ripening programme is crucial to control ripening under post-harvest conditions and thus to reduce massive spoilage of fruits during storage (<xref ref-type="bibr" rid="bib46">Michailides and Manganaris, 2009</xref>).</p><p>Ozone (O<sub>3</sub>), also known as triatomic oxygen, is a naturally occurring highly reactive form of oxygen. Ozone signalling in the induction of cell death and defence genes and interaction with other reactive oxygen species and ethylene is well documented in plants (<xref ref-type="bibr" rid="bib20">Castagna <italic>et al.</italic>, 2007</xref>). In addition, recent studies have demonstrated the benefits of post-harvest ozone application on fleshy fruits and vegetables. However, the specific mode of action of this molecule is not yet fully understood.

Specifically, mild oxidants, which are usually produced during fruit ripening (<xref ref-type="bibr" rid="bib58">Pedreschi <italic>et al.</italic>, 2008</xref>), signal through chemical reactions with specific atoms of target proteins resulting in covalent protein modifications, including oxidation, tyrosine nitration, S-nitrosylation, glutathionylation, and disulfide formation. Importantly, protein oxidation is expected to be a major component of the oxidative signalling that regulates many physiological outputs (<xref ref-type="bibr" rid="bib49">Møller <italic>et al.</italic>, 2007</xref>; <xref ref-type="bibr" rid="bib80">Wong <italic>et al.</italic>, 2010</xref>). Amongst a variety of methods for assessing oxidative-based protein modifications, protein carbonylation has been used (<xref ref-type="bibr" rid="bib36">Job <italic>et al.</italic>, 2005</xref>).

Currently, the cultivation of <italic>Actinidia</italic> and the post-harvest behaviour of kiwifruit are considered to be very important in Greece. The economic importance is due to the fact that Greece is one of the largest producers of kiwifruit in the world and over one-half of Greece’s kiwifruit production is exported. Besides such socioeconomic considerations, kiwifruit provides an excellent experimental model for investigating the post-harvest action of ozone. Indeed, kiwifruit displays non-climacteric behaviour at temperatures ≤10 °C (e.g. during cold storage) and climacteric behaviour at temperatures in the order of 20 °C (e.g. during ripening in most storage/conditioning rooms following cold storage, herein referred to as the shelf life) (<xref ref-type="bibr" rid="bib4">Antunes, 2007</xref>).

In the present study, two different assay systems, namely the FRAP and DPPH assays, were employed to determine kiwifruit total antioxidant capacity (<xref ref-type="fig" rid="fig3">Fig. 3</xref>). The FRAP assay can measure only hydrophilic antioxidants. Therefore, compounds such as lipophilic carotenoids cannot be detected. On the other hand, the DPPH assay can detect antioxidants soluble in organic solvents such as alcohols or hydro-alcohol mixtures. However, this assay suffers from steric inaccessibility and a narrow linear range of absorbance versus concentration (<xref ref-type="bibr" rid="bib6">Apak <italic>et al.</italic>, 2007</xref>). The antioxidant activity, as evaluated with the FRAP assay, increased in kiwifruits after 12 d of shelf life following 1 month of cold storage (<xref ref-type="fig" rid="fig3">Fig. 3A</xref>). Also, the DPPH assay showed that fruit stored in an ozone-enriched cold atmosphere for 1 or 5 months and then exposed at 20 °C for 6 d exhibited a higher antioxidant activity than control fruits (<xref ref-type="fig" rid="fig3">Fig. 3D,F</xref>). Both assays indicated that the ozone treatment stimulated antioxidant capacity after 3 months of cold storage plus 12 d of shelf life (<xref ref-type="fig" rid="fig3">Fig. 3B,E</xref>). Notably, both antioxidant assays revealed that ozone treatment stimulated antioxidant synthesis after 1 d of shelf life (<xref ref-type="fig" rid="fig3">Fig. 3A–F</xref>). Furthermore, ozone-treated fruits generally exhibited higher levels of ascorbic acid content compared with control fruits, particularly after 1 d of shelf life (<xref ref-type="fig" rid="fig4">Fig. 4A–C</xref>). In addition, the total phenolic content was increased throughout the shelf-life period in fruits subjected to 1-month cold storage in an ozone-enriched atmosphere (<xref ref-type="fig" rid="fig4">Fig. 4D</xref>), as well as in fruits subjected to a 3-month exposure to ozone in cold conditions followed by 12 d of shelf life (<xref ref-type="fig" rid="fig4">Fig. 4E</xref>).

In the present study, kiwifruit ripening was monitored during shelf life at 20 °C, following cold storage (0 °C, 95% relative humidity) in the absence (control) or presence of ozone (0.3 μl l<sup>−1</sup>) by measuring their tissue firmness, soluble solids content, titratable acidity, ethylene production, and respiration rate. Results showed that kiwifruits soften rapidly after transfer from low-temperature storage conditions (0 °C) to ripening temperatures (20 °C), which is consistent with the characteristic softening behaviour of this fruit (<xref ref-type="bibr" rid="bib38">Koukounaras and Sfakiotakis, 2007</xref>). However, it should be noted that ozone-treated kiwifruits displayed higher firmness retention, especially after 5 months of cold storage (<xref ref-type="fig" rid="fig1">Fig. 1A–C</xref>), than control fruits. This observation along with previous data (<xref ref-type="bibr" rid="bib77">Tzortzakis <italic>et al.</italic>, 2007a</xref>; <xref ref-type="bibr" rid="bib66">Rodoni <italic>et al.</italic>, 2010</xref>) suggests that ozone is efficient in promoting higher firmness retention. In addition, ozone-treated kiwifruits displayed lower soluble solids contents than control fruits. (<xref ref-type="fig" rid="fig1">Fig. 1D–F</xref>). Collectively, these data suggest that ozone is effective at suppressing ripening and senescence process, and therefore can extend kiwifruit post-harvest life.</p><p>Kiwifruit has a typical climacteric behaviour with ethylene playing a major role in the ripening process (<xref ref-type="bibr" rid="bib5">Antunes and Sfakiotakis, 2002</xref>). Control fruits showed a climacteric behaviour by starting autocatalytic production of ethylene when placed at 20 °C, though the exact starting time may depend on the duration of cold storage (<xref ref-type="fig" rid="fig2">Fig. 2A–C</xref>). Results regarding the impact of ozone on ethylene production during fruit ripening are contradictory and limited (<xref ref-type="bibr" rid="bib73">Skog and Chu, 2001</xref>; <xref ref-type="bibr" rid="bib56">Palou <italic>et al.</italic>, 2002</xref>; <xref ref-type="bibr" rid="bib77">Tzortzakis <italic>et al.</italic>, 2007a</xref>). The present study found that ozone delayed climacteric ethylene rise and totally blocked ethylene production in kiwifruits after intermediate (3 month) or extended (5 month) cold storage, respectively. Since the ethylene climacteric rise is tightly linked with kiwifruit softening (<xref ref-type="bibr" rid="bib5">Antunes and Sfakiotakis 2002</xref>), the present data revealed a key post-harvest function of ozone that could be the main aetiological reason for the markedly retarded ripening process (<xref ref-type="fig" rid="fig1">Fig. 1</xref>). This regulatory ozone-driven mechanism may provide an excellent model for further studies addressing the role of ethylene signal transduction pathway and ripening phenomena in climacteric fruits. The present data also demonstrated' that kiwifruit are characterized by a time lag between the increase in respiration rate and the induction of ethylene production, confirming previous observations (<xref ref-type="bibr" rid="bib70">Sfakiotakis <italic>et al.</italic>, 1997</xref>). In addition, respiration rates are enhanced by ozone treatment after short (<xref ref-type="fig" rid="fig2">Fig. 2D</xref>) or intermediate (<xref ref-type="fig" rid="fig2">Fig. 2E</xref>) cold storage and subsequent transfer to 20 °C. This fact, which was also observed by <xref ref-type="bibr" rid="bib27">Forney et al<italic>.</italic> (2007)</xref> in cold-stored vegetables, may indicate that kiwifruits experience physiological injury as a result of the oxidative stress caused by ozone exposure. However, the respiration rate is reduced in ozone-treated kiwifruits following extended cold storage compared with control fruits (<xref ref-type="fig" rid="fig2">Fig. 2F</xref>). This specific reduction in respiration may be related to the absence of climacteric peak of ethylene production in fruits exposed to ozone for 5 months (<xref ref-type="fig" rid="fig2">Fig. 2C</xref>), as previously suggested (<xref ref-type="bibr" rid="bib5">Antunes and Sfakiotakis, 2002</xref>).</p></sec><sec><title>Ozone acts as an antioxidant and anti-radical elicitor in kiwifruits during ripening</title><p>As kiwifruit is a good source of phytochemicals (<xref ref-type="bibr" rid="bib76">Tavarini <italic>et al.</italic>, 2008</xref>), the present study evaluated the antioxidant potency of kiwifruit extracts during shelf-life period. An induction of antioxidant activity, as measured by both FRAP and DPPH assays, was observed in ozone-treated kiwifruits, particularly after 1 d of shelf life (<xref ref-type="fig" rid="fig3">Fig. 3</xref>). These data indicated that the exposure of kiwifruits to ozone stimulated their antioxidant activity, presumably because of its action as a signal molecule for the activation of antioxidant-stress responses in kiwifruit, which possibly experienced an oxidative stress during the cold storage period. Although a variety of negative and positive interactions have been reported between ozone with either ascorbic acid (<xref ref-type="bibr" rid="bib3">Allende <italic>et al.</italic>, 2007</xref>; <xref ref-type="bibr" rid="bib76">Tavarini <italic>et al.</italic>, 2008</xref>) or phenolic compounds (<xref ref-type="bibr" rid="bib3">Allende <italic>et al.</italic>, 2007</xref>; <xref ref-type="bibr" rid="bib8">Artés-Hernández <italic>et al.</italic>, 2007</xref>; <xref ref-type="bibr" rid="bib78">Tzortzakis <italic>et al.</italic>, 2007b</xref>) in fruits undergoing post-harvest ripening, the present study further showed that ozone application may increase ascorbic acid and phenol content in kiwifruits, especially after 1 d of shelf life (<xref ref-type="fig" rid="fig4">Fig. 4</xref>).</p><p>Because of the differential patterns of the antioxidant-related parameters between ozone-treated and untreated kiwifruits ripened for 1 d at 20 °C after 1, 3, or 5 months cold storage (<xref ref-type="fig" rid="fig3">Figs. 3</xref> and <xref ref-type="fig" rid="fig4">4</xref>), this study investigated the relative phenolic-dependent anti-radical activity of kiwifruit extracts with respect to their protective abilities to counteract pBR322 DNA strand scission against HO, ONOO<sup>−</sup>, or ROO. Phenolics extracted from untreated fruits were quite effective at protecting radical-derived DNA scission (<xref ref-type="fig" rid="fig5">Fig. 5A,C,E</xref>), thus confirming earlier observations that kiwifruit extracts can protect DNA from oxidation (<xref ref-type="bibr" rid="bib22">Collins <italic>et al.</italic>, 2001</xref>). Both in-gel assay (<xref ref-type="fig" rid="fig5">Fig. 5A,C</xref>) and quantitative analysis (<xref ref-type="fig" rid="fig5">Fig. 5B,D</xref>) revealed that the phenolic extracts of ozone-treated kiwifruits were very potent in inhibiting DNA breakage induced by HO or ONOO<sup>−</sup>, thereby lending evidence that ozone acts as a potent anti-radical elicitor against commonly encountered oxidant and nitrosant damaging agents.</p></sec><sec><title>Characterization of kiwifruit proteome during ripening</title><p>Despite increasing interest in plant proteomics (<xref ref-type="bibr" rid="bib1">Agrawal <italic>et al.</italic>, 2011</xref>; <xref ref-type="bibr" rid="bib35">Job <italic>et al.</italic>, 2011</xref>), no systematic analysis of the kiwifruit proteome has been published. To fill this gap, 1D-PAGE coupled with mass spectrometry analysis was applied to characterize the reference proteomic map in kiwifruit during ripening at 20 °C. This allowed the characterization of 102 kiwifruit proteins (<xref ref-type="table" rid="tbl1">Table 1</xref>; see also <ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1">Supplementary Table S2</ext-link>), which is a substantial increase because on 25 August 2011 only 17 reviewed kiwi proteins were listed in the Uniprot/Swiss-prot database, of which only three were from kiwifruit (<ext-link ext-link-type="uri" xlink:href="http://www.uniprot.org/uniprot/?query=kiwi&sort=score">http://www.uniprot.org/uniprot/?query=kiwi&sort=score</ext-link>). The largest functional group of identified kiwifruit proteins is related to energy (<xref ref-type="fig" rid="fig6">Fig. 6B</xref>). This is a diverse group of proteins that includes proteins playing a role mainly in glycolysis and the tricarboxylic acid cycle. These proteins are expected to provide the necessary energy metabolites for the ongoing ripening process, as previously suggested in peach fruit (<xref ref-type="bibr" rid="bib61">Qin <italic>et al.</italic>, 2009b</xref>). The present analysis also showed the presence of various forms of malate dehydrogenase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 6, 14–17), enolase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 8–13), isocitrate dehydrogenase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 11), transaldolase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 14), glyceraldehyde-3-phosphate dehydrogenase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 15 and 17), fructose-bisphosphate aldolase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 15–20), NADPH quinone oxidoreductase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 18), and oxidoreductase NAD-binding (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 22 and 23), suggesting that during ripening, specific energy-related isoforms of kiwifruit proteins are presented. Another enzyme that may be linked to the energy group is the mitochondrial ATP synthase (F1) subunit β, which was also identified (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 8 and 9), possibly due to the increased demand for ATP during starch–sugar conversion in ripening kiwifruits. An interesting detection was the identification of maturase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 7). Chloroplast maturases evolved into general group II intron splicing factors, potentially mirroring a key step in the evolution of spliceosomal introns. The presence of the maturase in the kiwifruit proteome is indicative of ‘generation of precursor metabolites and energy’ as well as ‘metabolic compound salvage’ linking the splicing organellar introns to global signals that regulate gene expression in response to energy state (<xref ref-type="bibr" rid="bib48">Mohr and Lambowitz, 2003</xref>), thus suggesting a role for this maturase as an effector protein during kiwifruit ripening.</p><p>The second major functional group consisted of proteins involved in protein metabolism and modification (<xref ref-type="fig" rid="fig6">Fig. 6B</xref>), including proteins with chaperone function such as HSP70 (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 4). The accumulation of heat-shock proteins (HSPs) seems to be a common ripening regulatory mechanism in fruits (<xref ref-type="bibr" rid="bib30">Giribaldi <italic>et al.</italic>, 2007</xref>; <xref ref-type="bibr" rid="bib15">Bianco <italic>et al.</italic>, 2009</xref>; <xref ref-type="bibr" rid="bib51">Muccilli <italic>et al.</italic>, 2009</xref>; <xref ref-type="bibr" rid="bib42">Manganaris <italic>et al.</italic>, 2011</xref>) as these proteins play pivotal role in the degradation of damaged or misfolded peptides as occurs during fruit ripening (<xref ref-type="bibr" rid="bib26">Faurobert <italic>et al.</italic>, 2007</xref>). Also, the identification of 60S ribosomal protein (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 21 and 31) and eukaryotic translation initiation factor 5A (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 28) in kiwifruits during ripening is in accordance with the characterized role of these proteins in the regulation of pineapple fruit senescence (<xref ref-type="bibr" rid="bib50">Moyle <italic>et al.</italic>, 2005</xref>). Additionally, many proteins were identified, such as actinidin (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 9), cysteine protease (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 14), actinidin chain A (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 21), chymopapain (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 21), leucine aminopeptidase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 28), and cystatin (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 31), which are responsible for proteolysis and nitrogen recycling and could be involved in the degradation of damaged or misfolded peptides during ripening (<xref ref-type="bibr" rid="bib26">Faurobert <italic>et al.</italic>, 2007</xref>). Finally, the present study identified the biotin-dependent methylcrotonoyl-CoA carboxylase, an enzyme involved in leucine catabolism in all living cells and which in plants is strongly induced during leaf senescence (<xref ref-type="bibr" rid="bib2">Alban <italic>et al.</italic>, 2000</xref>). Therefore, this enzyme might be involved in maintaining leucine homeostasis during kiwifruit ripening.</p><p>A third major functional group consisted of proteins playing a role in plant defence. Considering that both low-temperature storage and fruit ripening are associated with oxidative processes (<xref ref-type="bibr" rid="bib58">Pedreschi <italic>et al.</italic>, 2008</xref>), the presence of reactive oxygen species-scavenging proteins in kiwifruits, such as glutathione reductase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 10) and peroxidase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 15), could be required for satisfying the cellular oxidative conditions favourable for ripening. In addition, 2-Cys peroxiredoxin (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 25) and small GTP-binding protein (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 26) were also identified. 2-Cys peroxiredoxins constitute an ubiquitous group of peroxidases that exhibit dual physiological functions both as antioxidant and molecular chaperone in response to oxidative stimuli (<xref ref-type="bibr" rid="bib7">Aran <italic>et al.</italic>, 2009</xref>), whereas small GTP-binding protein acts as a molecular switch in oxidative transduction cascades (<xref ref-type="bibr" rid="bib71">Shichrur and Yalovsky, 2006</xref>). The detection of such proteins in the present study supports their role in oxidative signalling during kiwifruit ripening. Further, the identification of nuclear glycine-rich RNA binding protein (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 31) in kiwifruit is in agreement with the observation that this protein performs a RNA chaperone function during cold adaptation (<xref ref-type="bibr" rid="bib37">Kim <italic>et al.</italic>, 2010</xref>). Since methylglyoxal (a metabolite deriving from glycolysis) is highly cytotoxic, it is also interesting to note the present identification of various forms of lactoylglutathione lyase in kiwifruit (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 17–19). This enzyme, also called glyoxalase I, catalyses the first step of the glyoxal pathway, in which methylglyoxal and glutathione are converted into S-lactoylglutathione, which is further converted into lactic acid (<xref ref-type="bibr" rid="bib34">Jia <italic>et al.</italic>, 2006</xref>). Thus the glyoxalase activity along with the identification of triosephosphate isomerase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 23), which is directly involved in the generation of methylglyoxal, likely reflects a mechanism to control the level of toxic methylglyoxal in kiwifruit, as previously proposed in pear fruit stored under long-term controlled-atmosphere conditions (<xref ref-type="bibr" rid="bib59">Pedreschi <italic>et al.</italic>, 2007</xref>).</p><p>Proteins belonging to the category of cell wall-modifying and structural proteins, such as pectinesterase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 9 and 10), endo-β-1,4-glucanase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 10), xyloglucan endotransglycosylase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 19), α-expansin (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 24 and 25), and pectinmethylesterase inhibitor (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 27 and 28), were also identified. The identification of cell wall-loosening proteins supports the pivotal role of cell-wall extensibility required for the softening process during kiwifruit ripening (<xref ref-type="fig" rid="fig1">Fig. 1C</xref>). Particularly relevant is also the identification of proteins related to metabolism of sugars/polysaccharides, such as β-galactosidase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 4) and α-galactosidase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 14). Both enzymes are able to release α- or β-linked <sc>D</sc>-galactose from polymers, oligosaccharides, or secondary metabolites and are responsible for most of cell-wall degradation and softening in kiwifruit (<xref ref-type="bibr" rid="bib67">Ross <italic>et al.</italic>, 1993</xref>). In addition, kiwifruit proteins involved in the regulation of growth, such as β-1,3-glucanase (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zone 19) and agglutinin (<xref ref-type="fig" rid="fig6">Fig. 6A</xref>, protein zones 8 and 9), may be also involved in the softening process as previously suggested (<xref ref-type="bibr" rid="bib17">Bogoeva <italic>et al.</italic>, 2004</xref>; <xref ref-type="bibr" rid="bib24">Deytieux <italic>et al.</italic>, 2007</xref>).</p><p>It is noted that several of the presently identified kiwifruit proteins, such as β-1,3-glucanase, malate dehydrogenase, eukaryotic translation initiation factor 5A, enolase, expansin, glyceraldehyde-3-phosphate, glycine-rich RNA binding protein, small GTP-binding protein, HSPs, isocitrate dehydrogenase, malate dehydrogenase, pectinesterase, and triosephosphate isomerase (<xref ref-type="table" rid="tbl1">Table 1</xref>; see also <ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1">Supplementary Table S2</ext-link>), have also been identified in a number of fruit species during their ripening (<xref ref-type="bibr" rid="bib65">Rocco <italic>et al.</italic>, 2006</xref>; <xref ref-type="bibr" rid="bib24">Deytieux <italic>et al.</italic>, 2007</xref>; <xref ref-type="bibr" rid="bib26">Faurobert <italic>et al.</italic>, 2007</xref>; <xref ref-type="bibr" rid="bib30">Giribaldi <italic>et al.</italic>, 2007</xref>, <xref ref-type="bibr" rid="bib29">2010</xref>; <xref ref-type="bibr" rid="bib59">Pedreschi <italic>et al.</italic>, 2007</xref>, <xref ref-type="bibr" rid="bib58">2008</xref>; <xref ref-type="bibr" rid="bib52">Negri <italic>et al.</italic>, 2008</xref>; <xref ref-type="bibr" rid="bib15">Bianco <italic>et al.</italic>, 2009</xref>; <xref ref-type="bibr" rid="bib51">Muccilli <italic>et al.</italic>, 2009</xref>; <xref ref-type="bibr" rid="bib55">Page <italic>et al.</italic>, 2010</xref>; <xref ref-type="bibr" rid="bib44">Martínez-Esteso <italic>et al.</italic>, 2011</xref>; <xref ref-type="bibr" rid="bib82">Zhang <italic>et al.</italic>, 2011</xref>), thus highlighting their general importance for the ripening process in fruits. In contrast to previous data obtained from studies with other climacteric fruits (<xref ref-type="bibr" rid="bib65">Rocco <italic>et al.</italic>, 2006</xref>; <xref ref-type="bibr" rid="bib26">Faurobert <italic>et al.</italic>, 2007</xref>; <xref ref-type="bibr" rid="bib55">Page <italic>et al.</italic>, 2010</xref>), the present study did not identify any proteins directly linked to ethylene metabolism in kiwifruit but cannot exclude the possibility that ethylene-related proteins were undetected due to the limited dynamic range afforded by classical gel-based proteomics, including 1D-SDS-PAGE analysis. Also, it has to be noted that a prerequisite for a separated protein to be identified is that it has either been sequenced in the organism being examined or that it shares a high sequence similarity with a sequenced protein from another organism (<xref ref-type="bibr" rid="bib16">Blomqvist <italic>et al.</italic>, 2008</xref>). It should be mentioned that the pattern of proteomic functional categories in kiwifruits (<xref ref-type="fig" rid="fig6">Fig. 6B</xref>) exhibits differences when compared with other fleshy fruit species. For example, the most abundant class of identified proteins in orange at ripening time belongs to sugar metabolism (<xref ref-type="bibr" rid="bib51">Muccilli <italic>et al.</italic>, 2009</xref>), whereas only few sugar-associated proteins were identified in kiwifruit (<xref ref-type="table" rid="tbl1">Table 1</xref>; see also <ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1">Supplementary Table S2</ext-link>), possibly indicating that the presence of a group of proteins is a fingerprint of particular fruit species during ripening. It should be pointed out that the present data represent the first proteomic reference map of kiwifruit that, along with a recent microarray-based study of gene expression patterns in ripe kiwifruit (<xref ref-type="bibr" rid="bib9">Atkinson <italic>et al.</italic>, 2011</xref>), may provide useful information for ripening marker selection in <italic>Actinidia</italic>. Large-scale 2D resolution approaches of the <italic>Actinidia deliciosa</italic> proteome and quantitative profiling studies are a necessary next step for gaining a better understanding of the active role of ozone and the relevant importance of individual kiwifruit proteins in the ripening process.</p></sec><sec><title>Protein carbonylation is increased during kiwifruit ripening</title><p>The remarkable antioxidant and anti-radical responses observed in ozone-treated fruits (<xref ref-type="fig" rid="fig3 fig4 fig5">Figs. 3–5</xref>) prompted this investigation of whether ozone treatment can modify the protein carbonylation status in kiwifruit during ripening. Quantitative evaluation of the immunoblot results (<ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1">Supplementary Fig. S3</ext-link>) together with the measurement of protein carbonyl group content (<xref ref-type="fig" rid="fig7">Fig. 7B</xref>) showed that protein carbonylation was progressively induced during ripening, thus confirming that protein oxidation is linked to fruit senescence (<xref ref-type="bibr" rid="bib62">Qin <italic>et al.</italic>, 2009a</xref>,<xref ref-type="bibr" rid="bib61">b</xref>). The observed lower levels of protein carbonyls in ozone-treated fruits during ripening compared with control fruits (<xref ref-type="fig" rid="fig7">Fig. 7B</xref>) may be a consequence of the inhibition of ethylene biosynthesis (<xref ref-type="fig" rid="fig2">Fig. 2C</xref>) and the relatively high antioxidant and anti-radical activity in ozone-treated fruits (<xref ref-type="fig" rid="fig3 fig4">Figs. 3 and 4C,F</xref> and <xref ref-type="fig" rid="fig5">Fig. 5A–D</xref>, respectively) and may be associated with delayed senescence features in kiwifruit (<xref ref-type="fig" rid="fig1">Fig. 1</xref>). Since previous studies have indicated that protein oxidation is not necessarily a deleterious phenomenon (<xref ref-type="bibr" rid="bib36">Job <italic>et al.</italic>, 2005</xref>; <xref ref-type="bibr" rid="bib54">Oracz <italic>et al.</italic>, 2007</xref>) but has been involved in cellular signalling (<xref ref-type="bibr" rid="bib80">Wong <italic>et al.</italic>, 2010</xref>), the overall pattern of protein carbonylation in kiwifruit (<xref ref-type="fig" rid="fig7">Fig. 7</xref>) raises the hypothesis that this redox modification is an important signalling mechanism governing fruit activity during ripening.</p><p>In summary, the use of an ozone-enriched cold atmosphere markedly delayed kiwifruit ripening at 20 °C compared with conventional storage. The present data also underscores that the delay/block of climacteric rise of ethylene production is a key mechanism targeted by ozone in kiwifruit upon ripening. Furthermore, this study provides evidence that ozone application during cold storage acts as an antioxidant and anti-radical elicitor in kiwifruit. This report is the first draft of the <italic>Actinidia</italic> proteome during ripening using 1D-SDS-PAGE and mass spectrometry techniques. A number of proteins that are related to energy, protein metabolism, defence, cell structure, and amino acid or sugar/polysaccharide metabolism are identified. In addition, this investigation shows that ripening and ozone specifically regulate kiwifruit protein carbonylation. These results provide insights into kiwifruit metabolism during post-harvest life and also a starting point to develop ozone-based treatments strategies for controlling fruit ripening and quality in practice.</p></sec></sec><sec><title>Supplementary material</title><p><ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1">Supplementary data</ext-link> are available at <italic>JXB</italic> online.</p><p><ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1"><bold>Supplementary Table S1</bold></ext-link><bold>.</bold> Quantification of protein zones from 1D-gels of kiwifruit proteins.</p><p><ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1"><bold>Supplementary Table S2</bold></ext-link><bold>.</bold> Detailed information of the identified kiwifruit proteins.</p><p><ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1"><bold>Supplementary Fig. S1</bold></ext-link><bold>.</bold> Scheme summarizing the experimental set up.</p><p><ext-link ext-link-type="uri" xlink:href="http://www.jxb.oxfordjournals.org/lookup/suppl/doi:10.1093/jxb/err418/-/DC1"><bold>Supplementary Fig. S2</bold></ext-link><bold>.</bold> Weight loss of kiwifruits (cv.
