“…Wang et al (2006) reported that the generation of reactive oxygen species and NO induced by UV-B radiation might serve as an early signalling molecule and be involved in UV-B stressinduced ethylene biosynthesis. In Arabidopsis guard cells, NO is involved in ethylene-induced stomatal closure (Liu et al 2010).…”

“…In Arabidopsis guard cells, NO is involved in ethylene-induced stomatal closure (Liu et al 2010). NO appeared to act in the same direction as or synergistically with reactive oxygen species to induce ethylene biosynthesis in leaves of maize (Zea mays L.) seedlings under UV-B radiation (Wang et al 2006). In A. thaliana, ethylene levels were enhanced significantly by exposure to NO gas (Magalhaes et al 2000).…”

The relationship between nitric oxide (NO) reduction and the inhibition of abscisic acid (ABA)-induced stomatal closure by ethylene was analysed. ABA treatment induced NO production and stomatal closure, but ethylene inhibited the effects of ABA on these two parameters. Like 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), a specific scavenger of NO, haemoglobin (Hb), the potent scavenger of NO/carbon monoxide (CO) and N G -nitro-LArg-methyl ester (L-NAME), an inhibitor of animal nitric oxide synthases (NOS; EC 1.14.13.39), both the ethylene-releasing compound 2-chloroethylene phosphonic acid (ethephon, ETH) and 1-aminocyclopropane-1-carboxylic acid (ACC), the immediate precursor of ethylene, were found to inhibit stomatal closure by ABA and to reduce NO levels by ABA in guard cells, indicating that the ethylene-caused inhibition of ABA-induced stomatal closure involves a decrease in NO levels in guard cells. In addition, and similar to cPTIO and Hb, ACC/ETH suppressed sodium nitroprusside (SNP)-induced stomatal closure and NO levels in guard cells treated with SNP in the light. ACC/ETH also reopened stomata that had been closed by ABA and reduced NO levels that had been generated by ABA, showing that ethylene causes NO removal in guard cells. However, the above-mentioned effect of ACC/ETH was dissimilar to that of L-NAME, which was incapable of reducing NO levels by SNP or abolishing NO that had been generated by ABA. We suggest that ethylene probably induces NO removal, thereby reducing NO levels in Vicia faba guard cells, and finally inhibits stomatal closure induced by ABA. Furthermore, the pattern of NO reduction caused by ethylene is also discussed.

“…Ethylene has many roles in various physiological processes, such as germination, growth, development, senescence and abscission as well as in defense and resistance (Wang et al 2002). Environmental stress induces the production of ethylene in large amounts (Wang et al 2006). Induction of ethylene biosynthesis has been shown in spring wheat during osmotic stress (Li et al 2004) and in maize under UV-B radiation (Wang et al 2006).…”

Environmental stresses result in the generation of reactive oxygen species (ROS) in plants. ROS accumulate in cells and lead to the oxidation of proteins, chlorophyll, lipids, nucleic acids, carbohydrates etc. Cells have evolved intricate defense systems including enzymatic (superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glutathione reductases (GR), monodehydroascorbate reductases (MSHAR), dehydroascorbate reductases (DHAR), glutathione peroxidase (GPX), guaicol peroxidase (GOPX) and glutathione-S-transferase (GST) and non-enzymatic systems such as ascorbic acid (ASH), glutathione (GSH), phenolic compounds, alkaloids, non-protein amino acids and α-tocopherol, which can scavenge the indigenously generated ROS. Plant stress tolerance mediated by antioxidants has been shown by many workers. Antioxidant resistance mechanisms may provide a strategy to enhance plant stress tolerance. Various enzymes involved in ROS-scavenging have been manipulated, over-expressed or down-regulated to add to the present knowledge and understanding of the role of antioxidant system. ROS induce the synthesis of several plant hormones, such as ethylene, salicylic acid (SA), jasmonic acid, brassinosteroids, abscisic acid (ABA) etc. These Phytohormones are required for growth and development of plants and defense responses during environmental stresses. The present review throws light on the enzymatic and non-enzymatic antioxidants in plants to enhance stress tolerance in plants and also in particular the role of brassinosteroids and ethylene during abiotic stress tolerance in plants.

“…Maize hypocotyl cells treated with SNP displayed the decrease of glucosidase activity and increase of protein content (Zhang et al 2003;. Wang et al (2006) reported that NO generated from NOS-like activity appeared to act in the same direction or synergistically with ROS to induce ethyl synthesis in defence response under UV-B radiation in maize leaves. Tossi et al (2009aTossi et al ( , 2012 showed that ROS widely occurred in chloroplasts and mesophyll cells of maize exposed to UV-B.…”
