“…Cell wall-bound POD enzyme activity in melon tissues treated with JA collaborates in H 2 O 2 production, but it is not the major factor, but implicates it in cells membrane stability disturbance resulted in transient leakage of important compounds into growth media. Liu et al (2008) found that cell wall POD activity in JA treated pea leaves were not parallel to the H 2 O 2 accumulation which is in line with our data. In the present work, assessing exogenous JA application on ascorbic acid metabolism revealed that JA modulates its content.…”

“…Peroxidases participate in a variety of defense mechanisms (Liu et al, 2008), to ameliorate oxidative burst a common event in defense response (Lamb and Dixon, 1997). In our work, induction of peroxidases (POD) in melon cells during the time course of elicitation, may result from enzyme activation and/or the de novo differential expression in POD isoforms, implicating them in stress alleviation, as POD expression is controlled by multiple genes (Gomez-vasquez et al, 2004).…”

“…and that exogenously supplied MJ at 100 µmol induced rapid production of NO concomitantly with the phenylalanine ammonia-lyase (PAL) activation. Liu et al (2008) found that 10 µmol JA treatment of pea leaves (Pisum sativum), led to a significant increase in activities of plasma membrane NADPH oxidase and PAL. Jasmonates elicitation was also found to increase the production of phenylpropanoids and naphtodianthrones in Hypericum perforatum cell suspensions (Gadzovska et al, 2007).…”

This study investigated whether a jasmonic acid (JA) elicitation strategy developed in a conventional cell suspension culture could evoke melon resistance mechanisms, including secondary metabolite production. Twenty one day cultured melon cell suspensions grown in MS1 medium were supplemented with JA at the concentrations of 0.5, 5.0 and 10 µmol. Melon cultures were sampled 24, 48 and 72 h post elicitation to evaluate different defense related factors such as antioxidant enzymes, ascorbate metabolism and phenolic compounds. Results suggest that melon cells respond to JA reprogramming the primary and secondary metabolism which will result in melon plantlets with enhanced resistance against diverse stress conditions through the production of specific bioactive molecules. Jasmonic acid elicited melon cells exhibited enhanced oxidative enzymes activities and ascorbic acid, coumarin and p-coumaric amounts were found without growth retardation. Induced intracellular JA functions as a signal transducer acting upstream to H 2 O 2 , which is a secondary messenger triggering jasmonic signaling cascades by activating certain late genes that regulate the activity of catalase, peroxidase and de novo synthesis of five isozymes, ascorbic peroxidase detoxifying enzymes concomitant with ascorbate compound. Secondary metabolite production in melon cells seems to be activated upon JA exposure suggesting that this cell culture could be used as a source for rapid and increased production of coumarin, p-coumaric, ascorbic acid and likely other specific phenylpropanoids. These data provides further evidences for a role of jasmonic acid in the intracellular signal cascade that results in the accumulation of secondary compounds and ultimately induced melon resistance. This approach could assist further in understanding the metabolic mechanisms operating in melon cells under stress, and thus how to control them.
