“…This indicates CaCl 2 and INA-treatment produce greater amount of NO in tomato leaves which ultimately scavenge excess amount of ROS and maintain a steady level. Similar reductions of MDA and H 2 O 2 in sodium nitroprusside (SNP, potent NO donor) applied seedlings were documented in various plants (Song et al 2006;Hasanuzzaman et al 2011;Kong et al 2011).…”

Improvement of the host resistance by using hazard free chemical elicitors is emerging as an alternative approach in the field of plant disease management. In our present work, we have screened the efficacy and possible mechanism of abiogenic elicitors like Dipotassium hydrogen orthophosphate (K 2 HPO 4 ), Oxalic acid (OA), Isonicotinic acid (INA), Salicylic acid (SA), Acetylsalicylate (AS), Arachidonic acid (AA) and Calcium chloride (CaCl 2 ) to stimulate innate immune responses in Lycopersicum esculentum Mill. Excised tomato leaves, treated with elicitors at three different concentrations, were found to stimulate defense and antioxidative enzymes, total phenol and flavonoid content after 24 h of incubation. CaCl 2 (0.5 %) followed by INA (2.5 mM) were found most effective in activation of all such defense molecules in tomato leaves. Furthermore, nitric oxide (NO), a key gaseous mediator in plant defense signaling, was also measured after subsequent elicitor application. Higher doses of elicitors showed an elevated level of reactive oxygen species (ROS) generation, enhanced lipid peroxidation rate and proline content, which indicates the extent of abiotic stress generation on the leaves. However, ROS production, lipid peroxidation rate and proline concentration remain significantly reduced as a result of CaCl 2 (0.5 %) and INA (2.5 mM) application. A sharp increase of total chlorophyll content was also recorded due to treatment of CaCl 2 (0.5 %). These results demonstrate the effects of different abiogenic elicitors to regulate the production of defense molecules. Results also suggest that among all such chemicals, CaCl 2 (0.5 %) and INA (2.5 mM) can be used as a potential elicitor in organic farming of tomato.

“…This indicated that exogenous NO has a key role in ROS scavenging and reduction of oxidative stress in wheat seedlings subjected to heat stress. Similar reductions of MDA and H2O2 in SNP treated seedlings were observed in many plant studies (Song et al, 2006;Kong et al, 2011). Zottini et al (2002) have reported previously that NO can affect plant mitochondrial functionality.…”

Protective Effect of Nitric Oxide on High Temperature Induced Oxidative Stress in Wheat (<i>Triticum aestivum</i>) Callus Culture

2016

High temperature (HT) stress is a major environmental factor that limits plant growth, metabolism and productivity worldwide. Plant growth and development involve numerous biochemical reactions that are sensitive to temperature. Plants' responses to HT vary with the degree and duration of HT and the plants' adaptability. The protective effect of exogenous nitric oxide in alleviating high temperature induced damages of wheat (Triticum aestivum) callus tissues was investigated. Heat treatment (35 and 40 °C) alone or in combination with 0.5 mM sodium nitroprusside (SNP; nitric oxide donor) was applied for 72 h to callus tissues cultured on MS medium. Heat stress significantly increased lipid peroxidation, hydrogen peroxide and superoxide anion radical levels, whereas ascorbate and total glutathione contents markedly decreased. In addition, heat stress increased the activities of antioxidant defense enzymes: superoxide distumase, ascorbate peroxidase and glutathione reductase. In contrast, the addition of SNP in the culture media prevented the callus from the heatinduced oxidative damage as indicated by the decrease of MDA, H 2 O 2 and O 2 .− contents, and increased the activities of antioxidant enzymes and non-enzymatic antioxidant constituents. These results provided support for the hypothesis that the exogenous applications of NO confer tolerance to high temperature stress by reducing the oxidative damage in plants.

“…Furthermore, exogenous trehalose and nitric oxide alleviated the heat stress-induced oxidative damage of Pleurotus sp. [28][29][30], and the overexpression of the methionine sulfoxide reductase A (MsrA) gene enhanced the heat tolerance of P. ostreatus [31]. Thus only few studies on the thermotolerance signal in higher basidiomycetes have been published.…”

Background/Aims: Heat stress could cause huge losses for Lentinula edodes in China and other Asian cultivation areas. Yet our understanding of mechanism how to defend to heat stress is incomplete. Methods: Using heat-tolerant and heat-sensitive strains of L. edodes, we reported a combined proteome and transcriptome analysis of L. edodes response to 40 °C heat stress for 24 h. Meanwhile, the effect of LeDnaJ on the thermotolerance and IAA (indoleacetic acid) biosynthesis in L. edodes was analyzed via the over-expression method. Results: The proteome results revealed that HSPs (heat shock proteins) such as Hsp40 (DnaJ), Hsp70, Hsp90 and key enzymes involved in tryptophan and IAA metabolism process LeTrpE, LeTrpD, LeTam-1, LeYUCCA were more highly expressed in S606 than in YS3357, demonstrating that HSPs and tryptophan as well as IAA metabolism pathway should play an important role in thermotolerance. Over-expression of LeDnaJ gene in S606 strains showed better tolerance to heat stress. It was also documented that intracellular IAA accumulation of S606 (8-fold up) was more than YS3357 (2-fold up), and exogenous IAA enhanced L. edodes tolerance to heat stress. Conclusion: Our data support the interest of LeTrpE, LeDnaJ, tryptophan and IAA could play a pivotal role in enhancing organism thermotolerance.
