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).

The aim of the present study was to determine the effect of high temperature stress (HT) and to evaluate the protective role of fungicide pretreatment against HT stress in tomato leaves. The oxidative stress was triggered under HT stress through an increase in the content of malondialdehyde (MDA) and hydrogen peroxide (H2O2). Also, it caused a decline in photosynthetic pigments and enhanced the proline in tomato. However, the activities of catalase (CAT; EC 1.11.1.6), peroxidase (POX; EC 1.11.1.7), and glutathione S-transferase (GST; EC.2.5.1.

In this study, the catalytic activity and stability of flowerlike hybrid horseradish peroxidase (HRP) nanobiocatalyst (HRPCu2+) obtained from Cu2+ ions and HRP enzyme in the polymerization reaction of guaiacol were analyzed. We demonstrated that HRP-Cu2+ and hydrogen peroxide (H2O2) initiator showed significantly increased catalytic activity and stability on the polymerization of guaiacol compared to that of free HRP enzyme. Poly(guaiacol) was observed with quite high yields (88%) and molecular weights (38,000 g/mol) under pH 7.

Excessive amounts of reactive oxygen species (ROS), unless counterbalanced by antioxidants, can cause cellular damage under oxidative stress conditions; therefore, antioxidative defenses against ROS must be measured. With the development of nanotechnology, nanoparticles have found numerous applications in science, health, and industries. Magnetite nanoparticles (Fe3O4 :MNPs) have attracted attention because of their peroxidase-like activity.

Furthermore, biochemical results were also in agreement with the molecular data, with enhanced antioxidant enzyme activities of peroxidase and catalase, and in couple with lower cellular content of the reactive oxygen species hydrogen peroxide in the transgenic plants. Taken these altogether, the transgenic plants might acquire advantages in dealing with oxidative stress using enzymes and proline, as well as cellular Na+ removal under salinity stress conditions.

In this study, with the aim of determining and assessing the influence of several culture conditions on the ligninolytic enzyme (LiP, MnP, and Lac) activity of bacteria, five lignin-degrading bacteria strains were isolated from two different soil samples and cultured on minimum salt medium agar containing alkaline lignin (MSML agar). Among the five isolated strains, DL1 and X3 expressed strong and stable ligninase enzyme activity at various temperature levels (30C, 37C, 50C, and 60C) and were selected for further study.

The inductive response of H2O2 scavenging enzymes was studied in leaves of twenty rice cultivars when the plants were exposed to elevated temperature 55 days after transplanting (DAT). High temperature stress preferentially enhance the activities of ascorbate peroxidase (APX) and non-specific oxidase (POX), catalase (CAT) activity decreased with continuous exposure to heat stress although it was higher than control upto 15 days of stress (DAS) treatment.

To achieve high seed vigour, seed priming can be utilized in definite manner in which three organic compounds viz. Naphthalene acetic acid (NAA), Salicylic acid (SA) and Nicotinic acid (NA) in diverse concentrations and treatment durations were applied for present analysis on Oat crop. In assessment of physiological performances of seed, the various parameters linked to seed germination, seedling quality and germination allied enzymes that showed evident disparity among dissimilar priming.

Since targeting oxidative stress markers has been recently recognized as a novel therapeutic target in cancer, it is interesting to investigate whether genetic susceptibility may modify oxidative stress response in cancer. The aim of this study was to elucidate whether genetic polymorphism in the antioxidant enzymes is associated with lipid peroxidation in breast cancer.

Studies on soybean GmNAC085 transcription factor revealed that the gene expression in plants was induced by water shortage treatments and its overexpression in the model plant Arabidopsis displayed improved plant tolerance characteristics towards drought stress. In this study, we continued analyzing the biological functions of GmNAC085 using transgenic soybean system overexpressing GmNAC085 gene, by targeting at a number of plant physiological features and biochemical activities in response to limited water growing condition.

This study was undertaken to find out the potential source of resistance of okra to yellow vein mosaic virus under natural epiphytic condition. The experiment was conducted with ten genotypes/cultivars at Main Vegetable Research Station and Department of Biochemistry, B.A. College of Agriculture, Anand Agricultural University, Anand. Out of ten genotypes/cultivars GAO-5 was registered with the higher of peroxidase and polyphenol oxidase activities and minimum number of whitefly population at 35 and 60 days after germination (DAS) as compared to rest of all genotypes.

A study was undertaken to investigate the effect of magnetic treatment on enzyme activation of paddy seed under laboratory and nursery conditions. A magnetic seed treater having aluminum container fitted with ten 250 gauss magnets on copper pipes in staggered fashion was used. The container could be rotated around the horizontal axis. The dry seeds were treated by putting the seeds in the container and rotated the container for different time periods (15 min without magnet (control) and 15, 30, 45, 60 and 90 min with magnet).
