“…However, pretreatment with 100 µM SA obviously reduced MDA accumulation and relative electrolyte leakage in jasmine leaves, exhibiting a potential to alleviate oxidative stress and maintain cell membrane integrity during cold stress. These results are consistent with previous studies in which SA pretreatment decreased MDA content and membrane leakage in cucumber (Zhang et al, 2011) and muskmelon (Korkmaz et al, 2007) after exposure to cold stress. In addition, it is important to note that SA inhibition of ROS generation and membrane damage reached peak levels on the ninth day of cold treatment, followed by a gradual decline, indicating a time-dependent effect of SA on alleviating cold damage.…”

Salicylic acid (SA) is a signal molecule that mediates many biotic and abiotic stress-induced physiological responses in plants.In the current study the protective effects of SA on cold stress-caused oxidative damage and photosynthesis inhibition in jasmine plants (Jasminum sambac) were examined. Jasmine seedlings were pretreated with 100 µM SA for 3 days and then subjected to cold stress (4 °C) for 15 days. The amounts of superoxide radicals (O 2 -) and hydrogen peroxide (H 2 O 2 ) significantly increased in leaves of plants exposed to cold stress and resulted in oxidative damage, indicated by an increase in malondialdehyde accumulation and membrane leakage. The total chlorophyll content, stomatal conductance (g s ), photochemical efficiency (F v /F m ), and net photosynthesis rate (P n ) were significantly reduced in response to the cold treatment. However, plants pretreated with exogenous SA (100 µM) exhibited significantly higher photosynthesis-related parameters and antioxidant enzyme activities (peroxidase and catalase) and lower reactive oxygen species levels compared with the cold control. It was therefore concluded that SA could alleviate the cold treatment-caused oxidative stress and photosynthesis decline by enhancing the activities of antioxidant enzymes in leaves of jasmine.

“…Salicylic acid is an important plant-produced signaling molecule involved in SAR ( Park et al, 2007 ). It is responsible for inducing tolerance to a number of biotic and abiotic stresses, which is also a trigger for the production of SAR-related enzymes ( Korkmaz et al, 2007 ). Thus, we established a method to detect the concentration of SA in LJ02FB-treated cucumber leaves (Figures 4A , B ).…”

Powdery mildew is a fungal disease found in a wide range of plants and can significantly reduce crop yields. Bacterial strain LJ02 is a biocontrol agent (BCA) isolated from a greenhouse in Tianjin, China. In combination of morphological, physiological, biochemical and phylogenetic analyses, strain LJ02 was classified as a new member of Bacillus amyloliquefaciens. Greenhouse trials showed that LJ02 fermentation broth (LJ02FB) can effectively diminish the occurrence of cucurbits powdery mildew. When treated with LJ02FB, cucumber seedlings produced significantly elevated production of superoxide dismutase, peroxidase, polyphenol oxidase and phenylalanine ammonia lyase as compared to that of the control. We further confirmed that the production of free salicylic acid (SA) and expression of one pathogenesis-related (PR) gene PR-1 in cucumber leaves were markedly elevated after treating with LJ02FB, suggesting that SA-mediated defense response was stimulated. Moreover, LJ02FB-treated cucumber leaves could secrete resistance-related substances into rhizosphere that inhibit the germination of fungi spores and the growth of pathogens. Finally, we separated bacterium and its fermented substances to test their respective effects and found that both components have SA-inducing activity and bacterium plays major roles. Altogether, we identified a BCA against powdery mildew and its mode of action by inducing systemic resistance such as SA signaling pathway.

“…The contents of hydrogen peroxide (H 2 O 2 ) and malondialdehyde (MDA) in the leaf samples were measured spectrophotometrically (Cary 100, Agilent) at 390 and 532 nm according to Alexieva et al (2001) and Dhindsa et al (1981), respectively. Electrolyte leakage (EL) was measured based on the method of Korkmaz et al (2007).…”

Melatonin (MEL) is a ubiquitous molecule with pleiotropic roles in plant adaption to stress. In this study, we investigated the effects of foliar spray of 100 and 200 μM MEL on the biochemical and physiological traits linked with the growth performance of olive seedlings exposed to moderate (45 mM NaCl) and severe (90 mM NaCl) salinity. Both salt stress conditions caused a considerable reduction in leaf relative water content and the contents of photosynthetic pigments (carotenoids, chlorophylls a and b, and total chlorophylls), K+ and Ca+2, while the contents of Na+ and the activities of antioxidant enzymes increased. In addition, salt‐stressed olive seedlings showed high accumulations of hydrogen peroxide (H2O2), malondialdehyde (MDA), and electrolyte leakage (EL), indicating that olive seedlings suffered from salinity‐induced oxidative damage. In contrast, MEL application revived the growth of olive seedlings, including shoot height, root length and biomass under salt stress conditions. MEL protected the photosynthetic pigments and decreased the Na+/K+ ratio under both moderate and severe salt stresses. Furthermore, MEL induced the accumulations of proline, total soluble sugars, glycine betaine, abscisic acid, and indole acetic acid in salt‐stressed olive seedlings, which showed a positive correlation with improved leaf water status and biomass. MEL application also increased the activities of catalase, superoxide dismutase, ascorbate peroxidase, and peroxidase in salt‐stressed seedlings, resulting in lower levels of H2O2, MDA, and EL in these plants. Taken together, MEL mitigates salinity through its roles in various biochemical and physiological processes, thereby representing a promising agent for application in crop protection.
