“…In particular, plants under salinity stress often face oxidative damage [ 44 , 45 , 46 ], a greater variation was also observed in our studies by observing production of reactive oxygen species (ROS) under salinity stress as indicated by thiobarbituric acid reactive substances ( Figure 4 ). The production of ROS might be due to loss of activity of antioxidant enzymes as previously reported in many plants under various abiotic stresses [ 47 , 48 , 49 ]. This negative effect was, however, recovered by supplement of silicon (Si) by decreasing the concentration of oxidative damages as shown by our study.…”

Tomato plants often grow in saline environments in Mediterranean countries where salt accumulation in the soil is a major abiotic stress that limits its productivity. However, silicon (Si) supplementation has been reported to improve tolerance against several forms of abiotic stress. The primary aim of our study was to investigate, using comparative physiological and proteomic approaches, salinity stress in chloroplasts of tomato under silicon supplementation. Tomato seedlings (Solanum lycopersicum L.) were grown in nutrient media in the presence or absence of NaCl and supplemented with silicon for 5 days. Salinity stress caused oxidative damage, followed by a decrease in silicon concentrations in the leaves of the tomato plants. However, supplementation with silicon had an overall protective effect against this stress. The major physiological parameters measured in our studies including total chlorophyll and carotenoid content were largely decreased under salinity stress, but were recovered in the presence of silicon. Insufficient levels of net-photosynthesis, transpiration and stomatal conductance were also largely improved by silicon supplementation. Proteomics analysis of chloroplasts analyzed by 2D-BN-PAGE (second-dimensional blue native polyacrylamide-gel electrophoresis) revealed a high sensitivity of multiprotein complex proteins (MCPs) such as photosystems I (PSI) and II (PSII) to the presence of saline. A significant reduction in cytochrome b6/f and the ATP-synthase complex was also alleviated by silicon during salinity stress, while the complex forms of light harvesting complex trimers and monomers (LHCs) were rapidly up-regulated. Our results suggest that silicon plays an important role in moderating damage to chloroplasts and their metabolism in saline environments. We therefore hypothesize that tomato plants have a greater capacity for tolerating saline stress through the improvement of photosynthetic metabolism and chloroplast proteome expression after silicon supplementation.

“…The phytotoxicity of SO 2 depends on its concentration and on the duration of exposure [1] and is influenced by sulfur status in plants [8] . The low dose of sulfur even can be useful to plants since sulfur is important for plants, and can help to alleviate other nutrient deficiencies in plants, such as that of Fe [9] . Sulfur is also a structural component of amino acids, proteins, vitamins and chlorophyll [8,10,11] .…”

A study was conducted to determine the effect of carbon monoxide (CO), nitroxide (NOx) and sulfur dioxide (SO2) on ROS production, photosynthesis and ascorbate–glutathione pathway in strawberry plants. The results showed that both singlet oxygen (O2−1) and hydrogen peroxide (H2O2) content increased in CO, NOx and SO2 treated strawberry leaves. A drastic reduction of primary metabolism of plants (photosynthesis), with the closure of stomata, resulted in a reduction of protein, carbohydrate and sucrose content due to production of reactive oxygen species (ROS) under prolonged exposure of gas stress. The resulting antioxidant enzymes were increased under a low dose of gas stress, whereas they were decreased due to a high dose of gas stress. Our results indicate that increased ROS may act as a signal to induce defense responses to CO, NOx and SO2 gas stress. The increased level of antioxidant enzymes plays a significant role in plant protection due to which strawberry plants can be used as a hyperaccumulator to maintain environmental pollution, however, the defense capacity cannot sufficiently alleviate oxidative damage under prolonged exposure of CO, NOx and SO2 stress.

“…Root mass was invariably higher under -Fe than +Fe conditions. Decrease in the number of functional proteins has also been reported under S and Fe deficiency (Muneer et al, 2013) which may be attributed to the depletion of biochemical attributes controlling signal transduction and gene function, due to excessive production of deleterious ROS (Luo et al, 2002;Choudhary et al, 2009). A better shoot mass with +S-Fe deficiency over -S-Fe condition could be related to a better ability of plants to cope up Fe deficiency in the presence of S (Astolfi et al, 2010).…”

“…Sulphur, an essential mineral nutrient, regulates plant metabolism, growth and grain yield production as component of amino acids such as cysteine and methionine besides having role in regulating several other important physiological functions (Muneer et al, 2013). Involvement of sulphur nutrition in nitrogen use efficiency in wheat (Salvagiotti et al, 2009) and Fe uptake in barley has been reported.…”
