“…These responses for NO 3¯d eprivation were mediated by enhancement of expression of related genes at least partly be mediated through ANT1 and SlJAF13 (Løvdal et al, 2010). However, the NO 3¯d eprivation effect on accumulation of phenolic compounds contents was restricted to the period of exposure (8 days as reported by Løvdal et al, 2010) which might explain the slight change in total phenolic compounds contents in this study.The present study shows that sulfur stress markedly increase in H 2 O 2 concentration in tomato leaves which in consonance with reports of Chandra and Pandey (2014) and Tewari et al, (2004). Impose of SO 4 2¯ deprivation was in parallel with that of NO 3¯d eprivation on tomato leaves.…”

The detection of hydrogen peroxide, chlorophyll pigments, anthocynin, carotenoids, total phenolic compounds and lipid peroxidation levels as potential stress signaling molecules in tomato (Lycopersicon esculentum Mill.) leaves in response to specific mineral deficiency were studied. The stress signaling molecules were measured in the plant leaves at different growth time points cultured in specific mineral deficient nutrient solutions. The results showed that hydrogen peroxide was significantly increased after 48 and 72h of growth in NO 3¯ and S deficient nutrient solutions. While the significant accumulation of H 2 O 2 in the plant leaves was observed after 72h and 96h of growth in K + deficient nutrient solution. 2¯ and NO 3¯ specific deficiencies after 48h and in the case of Mg 2+ deficiency after 72h. Meanwhile, SO 4 2¯d eficiency caused the significant increase of both after 72h and 96h. Regarding TPC the results clarified that Mg 2+ , Ca 2+ and K + specific deficiencies caused significant reductions that appeared after 48h. In contrast, S deficiency caused significant increase in TPC values after 72h. On the other hand, the estimated levels of MDA showed significant increment under Ca 2+ and K + and PO 4 2¯ specific deficiencies at all time points while in the case of Mg 2+ and Fe deficiencies the increment was first reported after 48h and with the later one (Fe) the increment continues up to 96h. These results indicate that some of presented metabolites could be used as stress markers. These results support the possible role of anthocyanins, carotenoids, hydrogen peroxide, total phenolic compounds contents and MDA as early signaling metabolites in tomato plants under specific mineral deficiency.

“…Biomass was reduced in sulfur stressed plants and reduction was more prominent in S-excess plants. Tissue S concentration and cysteine were increasing with increasing S supply from 1.0 to 8.0 mM S L −1 ( Table 1 ) which is in consonance with the results of Chandra and Pandey [ 30 , 32 ]. It is generally well known that the uptake and assimilation of sulfate is induced under conditions of sulfur starvation or high demand, for sulfur metabolites.…”

A pot culture experiment was carried out to assess the effect of sulfur stress on growth, oxidative status, and antioxidative metabolism. Onion plants were treated with three different levels of sulfur, namely, 1.0, 4.0, and 8.0 mM S L−1. Plants raised with 4.0 mM S L−1 represent sufficient growth for the best vegetative yield. Plants supplied with 1.0 and 8.0 mM S L−1 showed retarded growth, chlorosis, and reduction in biomass and photoassimilatory pigments. Tissue sulfur concentration and cysteine were increased with increasing sulfur supply. Carbohydrates (sugars and starch) were accumulated in sulfur stressed plants. Hydrogen peroxide levels were increased in sulfur stressed plants. Thiobarbituric acid reactive substances levels were also increased which was an indicator of lipid peroxidation. Enzymatic (superoxide dismutase, catalase, peroxidase, ascorbate peroxidase, and glutathione reductase) and nonenzymatic (asorbate) antioxidative components were enhanced in sulfur stressed plants. Glutathione was increased with increasing sulfur supply. The present study showed that the adverse effects of inadequate sulfur supply result in irregular metabolic activities and antioxidant machinery.

One of the major effects of salt stress is high production of reactive oxygen species that adversely affect essential cellular metabolic pathways. To limit the elevated production of reactive oxygen species, plants stimulate various types of antioxidants. In this study, sulfur was used to induce tolerance against oxidative stress through modulation of the activities of various antioxidants. Two maize genotypes (Agatti 2003 and Pak Afgoi 2003) were subjected to different salinity (25 and 75 mM) and sulfur (40 and 80 mM) treatments and a control treatment. Various antioxidants and oxidative stress determinants in maize organs (leaf, shoot, and root) were studied. It was found that salt stress decreased ascorbic acid and tocopherol, but stimulated the production of total phenolics, carotenoids, lycopene, superoxide dismutase, peroxidase, catalase, malondialdehyde, and hydrogen peroxide. Exogenously applied sulfur decreased carotenoids, malondialdehyde, and hydrogen peroxide and increased ascorbic acid, tocopherol, total phenolics, lycopene, superoxide dismutase, peroxidase, and catalase. Agatti 2003 showed higher antioxidant activity than Pak Afgoi 2003. In conclusion, sulfur application at the 40 mM level balanced antioxidants and oxidative stress determinants to induce salt tolerance in maize plants.
