“…Salicylic acid regulates the antioxidant enzymes under stressful condition and maintain the redox state of cell (Chen et al, 2016) 39 . It is reported from higher plants that SA + PQ treatment provide the protection against PQ induced toxicity by activation of antioxidant enzymes in to barley 36 and in Vigna radiate under mancozeb (fungicide), chlorpyrifos (insecticide), under metribuzin (herbicide) 15 and in rice plant 18 under quinclorac toxicity.…”

Weeds are the worst category of agricultural pests as they compete with crops for water, nutrients, and light, grow faster than crops and eventually reduces the crop productivity thereby increasing the production cost. Herbicide has been used as a management tool to control weeds, by modifying their physiological activities like reducing photosynthesis, increasing protease activity and free radicals etc. The application of non-selected herbicides kills not only the weeds but also non-target organisms including the main crop. Herbicides like paraquat have been used in rice fields but its toxic effects on other organisms is at par. Salicylic acid, a plant growth regulator, is known to regulate oxidative stress in plants subjected to unfavourable environmental conditions. Given this, the present study was designed to study the effect of salicylic acid in Microchaete sp. NCCU-342 exposed to paraquat. The results obtained demonstrated that the paraquat toxicity elevated MDA and H2O2 levels, indicating free radical formation. However, supplementation of salicylic acid in the culture medium reduced the paraquat toxicity. The content of MDA and H2O2 in presence of salicylic acid was similar to the control. It enhances phenolic compound (29.07%) and phytohormones content (IAA-2.96%, SA-96.59%) and regulate the redox state of the cells. A significant change (recorded in percentage) was observed in the antioxidant enzyme activities including SOD (121.62 %), CAT (30.38 %), APX (74.38 %), GPX (127 %) and GR (141%) in presence of paraquat and after supplementation of salicylic acid. Antioxidant assay confirmed the change in antioxidants in form of phenolic compounds. Salicylic acid supplementation also enhanced the antibacterial activity of cyanobacteria, highlighting that it induces resistance against biotic stress as well as the abiotic stress. This work provides evidence for the ability of salicylic acid to alleviate the paraquat-induced toxicity, maintain redox state and resist the cell against both biotic and abiotic stress.

“…Ferreira et al [42] reported an increase in the activity of SOD in potato plants against oxidative damage cause by oxychloride fungicide applications. Moreover, upregulation in the activities of SOD, POD and CAT has been reported by various research groups using vigna radiata [43], tomato [44] and and Brassica campestris [45] as test plant species under various pesticidal stresses. Furthermore, Chris et al [46] observed enhanced activity of SOD or POD in A. filiculoides exposed to pesticide monocrotophs.…”

Pesticides are usually used to eliminate weeds and insects to improve crop quality and yield. The present study was undertaken to explore pesticides (Lambda cyhalotherin (LC) and Emamectin benzoate (EB)) related physiological, biochemical and ultrastructural changes in leaves of maize seedlings at different concentrations of LC and EB both singly (LC 100 , LC 500 , LC 800 , EB 100 , EB 300 , EB 600 mg/L) and jointly (LC 500 + EB 300 mg/L) along with control. Germination percentage, root stem and leaf lengths increased at lower concentrations of both pesticides and significantly decreased with the increase in the external application of pesticides. At higher concentrations of LC and EB (i.e., LC 800 and EB 600 mg/L) the mean values of growth and biomass of maize leaves were lower than control. Also, decreases in photosynthetic pigments and ion concentration of Na 1+ , Ca 2+ and K 1+ were significant when the concentration of both pesticides increased. The melondialdehyde (MDA) contents decreased, while the amount of hydrogen peroxide (H 2 O 2) production increased at higher doses in cases of single and joint applications. With the increase in their concentrations, the activities of antioxidant enzymes such as superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were found to be pronouncedly enhanced as compared to control. Ultrastructural alterations in mesophyll cells of maize leaf were mostly found in chloroplast and nucleus. The present study revealed that short-term exposure of maize

“…Transgenic NahG in rice plants causes SA deficiency, with lower glutathione (GSH) content showing great sensitivity to paraquat exposure [ 158 ]. SA significantly increases enzymatic parameters and photosynthetic pigments of Vigna radiata when exposed to fungicide (mancozeb), insecticide (chlorpyrifos), and herbicide (metribuzin) [ 161 ]. Pre-treatment with 1 mM SA triggers the activity and expression of pesticide detoxification enzymes (GSTs: glutathione S-transferases; a carbon-monoxide-bound enzyme, P450 (absorption band at 450 nm)) in thiram-treated leaves [ 162 ].…”

In recent decades, many new and exciting findings have paved the way to the better understanding of plant responses in various environmental changes. Some major areas are focused on role of phytohormone during abiotic stresses. Salicylic acid (SA) is one such plant hormone that has been implicated in processes not limited to plant growth, development, and responses to environmental stress. This review summarizes the various roles and functions of SA in mitigating abiotic stresses to plants, including heating, chilling, salinity, metal toxicity, drought, ultraviolet radiation, etc. Consistent with its critical roles in plant abiotic tolerance, this review identifies the gaps in the literature with regard to the complex signalling network between SA and reactive oxygen species, ABA, Ca2+, and nitric oxide. Furthermore, the molecular mechanisms underlying signalling networks that control development and stress responses in plants and underscore prospects for future research on SA concerning abiotic-stressed plants are also discussed.
