“…In this respect, an increase in lipid peroxidation, and the concomitant production of MDA, was reported in different plants as a response to environmental stresses (Cakmak and Horst, 1991;Xu et al, 2012) and has been associated with plant tissue senescence. Our results indicated that although increases in MDA content in skin were not significant, there was a significant increase in rachis and pulp of non-treated table grapes as a response to low temperature storage, though different trends of accumulation were observed between both tissues.…”

Rachis browning is one of the main factors reducing the quality of table grapes during storage at low temperature. To better understand the effect of a 3-day CO 2 pretreatment (20% CO 2 plus 20% O 2 ) on maintaining the rachis quality of table grapes (Vitis vinifera cv. Cardinal) 5 at 0 ºC, we analyzed the expression of genes codifying enzymes related to the synthesis and oxidation of phenolic compounds (phenylalanine ammonia-lyase, VcPAL; and polyphenol oxidase, GPO) and the detoxification of reactive oxygen species (catalase, GCAT; and ascorbate peroxidase, VcAPX) in rachis of treated and non-treated bunches. Furthermore, due to their role in senescence, the implication of ethylene and abscisic acid (ABA) was also 10 investigated by studying the expression pattern of key regulatory genes for these hormones such as ACC synthase (ACS1) and oxidase (ACO1), VvNCED1 and 2. To determine whether these changes in gene expression were specifically related to rachis deterioration, their expression pattern in pulp and skin of treated and non-treated grapes were evaluated. The appearance of browning in non-treated rachis was associated with an increase in GPO and 15VcPAL mRNA levels, whereas high CO 2 levels arrested this accumulation. In pulp, even though browning was not evident, a slight increase in GPO accumulation in non-treated bunches was detected. Moreover, lipid peroxidation level revealed lower oxidative stress in rachis of CO 2 -treated bunches than in non-treated ones, which seemed to be regulated by VcAPX and GCAT gene expression induction. Interestingly, this regulation was specific to rachis, showing a 20 different pattern in pulp and skin. Regarding phytohormones, our results pointed to the participation of the ethylene biosynthesis pathway in rachis browning. On the other hand, neither VvNCED1 nor VvNCED2 expression levels were altered in rachis, but NCED1 was induced specifically by low temperature in pulp. Overall, our results suggest a specific response of rachis to high levels of CO 2 that could be related to the mitigation of rachis browning. 25

“…The formation of NO following exposure to low temperature has been observed in a range of plant species belonging to different families from both monocots and dicots (Table 8.1) (Shimoda et al 2005;Corpas et al 2008;Zhao et al 2009;Liu et al 2010;Cantrel et al 2011;Airaki et al 2012;Bai et al 2012;Majláth et al 2012;Xu et al 2012). NO generation is therefore a frequent response of plants submitted to cold stress.…”

“…This is in accordance with a higher NO synthase-like activity in extracts from chilled plants (Corpas et al 2008). On the other hand, nitrate reductase (NR) activities have been implicated in NO formation in chilled Arabidopsis, loquat fruit and Baccaurea ramiflora embryos (Zhao et al 2009;Cantrel et al 2011;Bai et al 2012;Xu et al 2012). The determination of the overall NO content of chilled plants may underestimate the quantity of NO produced as it integrates turnover processes.…”

“…Using fumigation with NO gas or treatments with NO-releasing chemicals, several studies have correlated the capacity of NO to prevent chilling injury with the up-regulation of the antioxidant defence (Singh et al 2009;Liu et al 2010;Zaharah and Singh 2011;Bai et al 2012;Xu et al 2012;Esim et al 2012). NO treatment has been shown to enhance GSH and ascorbate contents and to increase superoxide dismutase, catalase and ascorbate peroxidase activities, while decreasing O 2 − and H 2 O 2 levels.…”

“…NO treatment has been shown to enhance GSH and ascorbate contents and to increase superoxide dismutase, catalase and ascorbate peroxidase activities, while decreasing O 2 − and H 2 O 2 levels. The regulation of antioxidant capacity by NO might be particularly important for the post-harvest physiology of fruits and seeds conserved at low temperature (Singh et al 2009;Zaharah and Singh 2011;Bai et al 2012;Xu et al 2012). It is to note that this effect might proceed via the alleviation of ethylene formation (Singh et al 2009;Zaharah and Singh 2011).…”

Nitric Oxide Action in Abiotic Stress Responses in Plants

Low temperature constitutes a major constraint for plant development and spreading and imprints plant biodiversity. Plant tolerance towards cold is a complex matter that relies on deep metabolic reprogramming principally governed by transcriptomic changes themselves controlled through multiple signalling pathways. A set of recent reports points out nitric oxide (NO) as a key element of signalling networks underlying plant response to low temperature. Based on the identification of several cold-regulated NO-dependent genes, that play key functions during plant response to temperature lowering, NO might sustain major functions during cold stress. This chapter summarizes our current knowledge on NO availability and bioactivity during low-temperature response, with a special emphasis on its implication in the regulation of gene expression.
