“…7. Interactions of some of the volatiles like; C 2 H 4 , O 2 , CO 2 , SA/MeSA, JAs and NO on various components of respiratory metabolism was reported by Millar and Day (1996), Fan et al (1997), Yang et al (1998), Ederli et al (2006), Leakey et al (2009) and Wang et al (2010). This shows that different volatiles and gases can affect the status of respiration which in turn is closely linked with the potential shelf-life of plant parts (including fruits) after their harvest (Kader 1987;Kader and Saltveit 2003b;Varoquaux and Ozdemir 2005;Paul and Srivastava 2006;Paul et al 2010b).…”

Concentrations of different gases and volatiles present or produced inside a fruit are determined by the permeability of the fruit tissue to these compounds. Primarily, surface morphology and anatomical features of a given fruit determine the degree of permeance across the fruit. Species and varietal variability in surface characteristics and anatomical features therefore influence not only the diffusibility of gases and volatiles across the fruits but also the activity and response of various metabolic and physiological reactions/processes regulated by these compounds. Besides the well-known role of ethylene, gases and volatiles; O 2 , CO 2 , ethanol, acetaldehyde, water vapours, methyl salicylate, methyl jasmonate and nitric oxide (NO) have the potential to regulate the process of ripening individually and also in various interactive ways. Differences in the prevailing internal atmosphere of the fruits may therefore be considered as one of the causes behind the existing varietal variability of fruits in terms of rate of ripening, qualitative changes, firmness, shelf-life, ideal storage requirement, extent of tolerance towards reduced O 2 and/or elevated CO 2 , transpirational loss and susceptibility to various physiological disorders. In this way, internal atmosphere of a fruit (in terms of different gases and volatiles) plays a critical regulatory role in the process of fruit ripening. So, better and holistic understanding of this internal atmosphere along with its exact regulatory role on various aspects of fruit ripening will facilitate the development of more meaningful, refined and effective approaches in postharvest management of fruits. Its applicability, specially for the climacteric fruits, at various stages of the supply chain from growers to consumers would assist in reducing postharvest losses not only in quantity but also in quality.

“…Among these AOX genes, AOX1a is the most intensively studied and is the most responsive to stress. In Arabidopsis, this gene is induced by most abiotic stresses including drought, chilling, high salt, high light, and limitation of nitrogen [4,6,23,40,41]. Furthermore, using transgenic A. thaliana with varying expression levels of AOX1a, it demonstrated that the induction of AOX1a under abiotic stresses is actually associated with the tolerance of plants.…”

“…Many studies showed that most, if not all, abiotic stresses, including drought, high salinity, chilling, high light, high temperature, metal toxicity, and nutrient limitation can increase the amounts of AOX protein or mRNA [3][4][5][6][7][8][9][10][11]. In recent years, transgenic plants with varying levels of AOX gene expression have provided molecular evidence that AOX actually contributes to abiotic stress tolerance [10, [12][13][14][15][16][17][18].…”

Plants in their natural environment frequently face various abiotic stresses, such as drought, high salinity, and chilling. Plant mitochondria contain an alternative oxidase (AOX), which is encoded by a small family of nuclear genes. AOX genes have been shown to be highly responsive to abiotic stresses. Using transgenic plants with varying levels of AOX expression, it has been confirmed that AOX genes are important for abiotic stress tolerance. Although the roles of AOX under abiotic stresses have been extensively studied and there are several excellent reviews on this topic, the differential expression patterns of the AOX gene family members and the signal regulation of AOX gene(s) under abiotic stresses have not been extensively summarized. Here, we review and discuss the current progress of these two important issues.

“…The concentration of the stress hormone abscisic acid (ABA) increased after SNP treatment in the leaves of wheat seedlings (Ruan et al 2004b) but ethylene production decreased in the wild type but not in ethylene receptor mutant, etr1-3 Arabidopsis callus cultures (Wang et al 2010c).…”
