Ebook "Sulfur assimilation and abiotic stress in plants" discusses the aspects of sustainable crop production with sulfur, the importance of sulfur metabolites and sulfur metabolizing enzymes in abiotic stress management in plants. Sulfur is one of the four major essential elements necessary for the plant life cycle. Its assimilation in higher plants and its reduction in metabolically important sulfur compounds are crucial factors determining plant growth and vigor and resistance to stresses.

Long-term mechanical ventilation with hyperoxia can induce lung injury. General anesthesia is associated with a very high incidence of hyperoxaemia, despite it usually lasts for a relatively short period of time. It remains unclear whether short-term mechanical ventilation with hyperoxia has an adverse impact on or cause injury to the lungs.

Hydropriming has the potential to ameliorate the stress-induced ill effects on yields of the crop plants and quality of seed produced. In the present study, half of the fresh seeds of maize hybrid, PEHM 5 and its parental lines (Female - CM 150, Male - CM 151) were subjected to accelerated aging test for bringing down the viability and vigour, thereby creating low vigour lots while high vigour lots consisted of fresh seeds, which were hydroprimed (30 h at 25°C). Half of the hydroprimed seeds were surface dried while the other half were redried back to the original moisture contents.

This study intended to focus on the effect of different levels of NaCl (0–400 mM, at regular intervals every 100 mM) on the growth, secondary metabolites, and antioxidant enzyme activities of Polygonum equisetiforme, a wild plant with medicinal and industrial uses, which often grows in harsh environmental conditions. Our results showed that biomass production significantly decreased with salinity, while the leaf relative water content declined only at high levels of NaCl concentration (300–400 mM).

Ferulic acid (FA; 3-methoxy-4-hydroxycinnamic acid) can eliminate stress-induced damage because of its ability to induce antioxidant activity under stress. The aim of this study was to identify the effects of FA on water status, antioxidant system, and lipid peroxidation in wheat (Triticum aestivum L.) roots exposed to boron (B) stress. Plants were grown in hydroponic culture containing the combination or alone form of 25–75 μM FA and 4–8 mM B. Stress significantly decreased growth (RGR), water content (RWC), proline content (Pro), and osmotic potential (YP).

Glutathione reductase (GR, EC 1.8.1.7) is an antioxidant enzyme and is involved in the reducing reaction of oxidized glutathione. Glutathione and reduced glutathione are very crucial for micro- and macroorganisms because of their barrier function against radicals. Therefore, the aim of this article was to purify GR and evaluate the relationship between purified GR and vitamins. GR was purified from bovine liver using 2’,5’-ADP Sepharose 4B column materials. To check the purity of each subunit of the enzyme, SDS-PAGE electrophoresis was performed and each one was 55 kDa.

A Total 8 semen sample from four healthy Gir breeding bulls were collected at weekly interval for two weeks period using of artificial vagina method for evaluation of semen biochemical attributes at various stages of cryopreservation of Gir bull semen. The overall mean values for oxidative stress parameters viz. lipid peroxidation and glutathione reductase were 51.14 ± 0.18 μmol/ml and 32.24 ± 0.64 U/L, respectively in neat semen samples.

Presoaking maize (Zea mays) seeds in salicylic acid (SA) reduces damage caused by cadmium. In the present work the possible role of phytochelatins (PCs) in SA-mediated protection against Cd toxicity was investigated. Seeds were presoaked in 0.5 mM SA, and seedlings were grown in hydroponic solution containing 0, 0.01, 0.015, or 0.025 mM Cd.

Human erythrocyte glutathione disulfide reductase studied at 37˚C in 100 mM potassium phosphate buffer, pH 7.4, is subject to partial inhibition by GSSG at low [NADPH]. Saturation by NADPH is hyperbolic at low [GSSG] and becomes increasingly sigmoidal at high [GSSG]. NADP+ is a competitive inhibitor with respect to NADPH at 20-1000 µM GSSG and an uncompetitive inhibitor with respect to GSSG at 33-120 µM NADPH.

Changes in antioxidative enzymes of young and mature leaves of tomato seedlings under drought stress
The effects of exogenous abscisic acid (ABA) on antioxidant enzymes of young and mature leaves of 4-week old Lycopersicon esculentum cv. Ailsa Craig and ABA-deficient mutant, notabilis, were investigated under drought stress. Although ABA induced increases in ascorbate peroxidase (APX), glutathione reductase (GR) and catalase (CAT) activities in drought-stressed young leaves of notabilis, CAT activities remained unchanged in both ABA-treated young and mature leaves of Ailsa Craig under drought.

The Akhisar 97 variety was found to be more sensitive to salinity stress than the İzmir Özbaş variety. Although proline is thought to accumulate in salt-tolerant plants, we found a negative correlation between salinity tolerance and proline accumulation in the plants.

Ultraviolet B (UV-B) irradiation has an adverse effect on plant cells because it causes the generation of reactive oxygen species (ROS). This is scavenged by some endogenous defense systems. In this study, the activities of H2O2- detoxifying antioxidant enzymes in 4 barley cultivars pretreated with high temperature or NaCl before UV-B irradiation were investigated.
