The role of morpho-physiological attributes along with the antioxidant potential of Stipagrostis plumosa L. populations collected from arid regions in adaptability to aridity was evaluated. Root to shoot length, chlorophyll, carotenoids, and organic osmolytes (total free amino acids, total soluble proteins, glycinebetaine, and proline) increased with more activities of antioxidant enzymes (APX, CAT, POD, and SOD).

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.

The obtained results show that FeNPs added to MS medium was higher growth, chlorophyll (a, b and a+b) content, antioxidant activity of SOD and APX enzymesthan Fe-EDTA in MS medium as control treatment. The effect of FeNPs are differences between culture systems. In vitro solid and microponic culture systems, the optimal concentration is 75 mM FeNPs and in vitro hydroponic culture system is 100 mM FeNPs.

Low-temperature severely affects the growth and development of chrysanthemum which is one kind of ornamental plant well-known and widely used in the world. Lysine crotonylation is a recently identified posttranslational modification (PTM) with multiple cellular functions. However, lysine crotonylation under lowtemperature stress has not been studied.

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.

We compared the enzymatic antioxidative defence mechanisms of some regional soybean genotypes cultivated mainly in the regions of Maharashtra and Chhattisgarh. The variability in the activities of antioxidant enzymes superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT), and peroxidase (POD) and their changes under drought stress were investigated. The higher activity levels of antioxidant enzymes may contribute to better stress tolerance by increasing protection capacity against oxidative damage.

Present study was investigated to elucidate the role of antioxidative enzymes in imarting resistance to sucking pest attack. Antioxidative enzymes viz. SOD, CAT, POX, GR and APX were estimated in the leaves (2nd leaf & 6th leaf) of cotton genotypes infected by sucking pests at 50, 60 and 68 days after sowing (DAS) stage. The antioxidative enzyme activity before infection was maximum in 2nd & 6 th leaves of G. arboreum genotypes followed by G. hirsutum resistant genotypes and minimum in G. hirsutum susceptible genotypes.

Physiological parameters and expression levels of drought related genes were analyzed in early vegetative stage of two bread wheat cultivars (Sids and Gmiza) differ in drought tolerance capacity. Both cultivars were imposed to gradual water depletion started on day 17 till day 32 after sowing. Sids, the more tolerant cultivar to drought showed higher fresh and dry weights than the drought sensitive genotype, Gmiza.

The impact of aluminium (Al) stress on the production of hydrogen peroxide and on the activity of antioxidant enzymes involved in oxidative metabolism, such as ascorbate peroxidase (APX), peroxidase (POD), and catalase (CAT), were studied in seedlings of 2 clover species (Trifolium alexandrinum L. and Medicago sativa L.).

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 effects of cadmium (Cd) on antioxidant responses and sister chromatid exchanges (SCE) were studied in Vicia faba L. The activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR), and the levels of ascorbate (ASC), glutathione (GSH), hydrogen peroxide, and malondialdehyde (MDA, indicator of lipid peroxidation) were measured.
