“…24 Moreover, expression of HO-1 in plants is regulated by ultraviolet-B (UV-B), H 2 O 2 , nitric oxide (NO), cytokinin, and heavy metals. 18,20,[25][26][27][28][29] Heme catabolism also gives rise to CO production, and this molecule can participate in many physiological reactions, 30 including cell protection against oxidative stress.…”

Objectives: This study was focused on the role of indole acetic acid (IAA) in the defense against oxidative stress damage caused by drought in soybean plants and to elucidate whether heme oxygenase-1 (HO-1) and nitric oxide (NO) are involved in this mechanism. IAA is an auxin that participates in many plant processes including oxidative stress defense, but to the best of our knowledge no information is yet available about its possible action in drought stress. Methods: To this end, soybean plants were treated with 8% polyethylene glycol (PEG) or 100 μM IAA. To evaluate the behavior of IAA, plants were pretreated with this compound previous to PEG addition. Lipid peroxidation levels (thiobarbituric acid reactive substances (TBARS)), glutathione (GSH) and ascorbate (AS) contents, catalase (CAT), superoxide dismutase (SOD), and guaiacol peroxidase (POD) activities were determined to evaluate oxidative damage. Results: Drought treatment (8% PEG) caused a significant increase in TBARS levels as well as a marked decrease in the non-enzymatic (GSH and AS) and enzymatic (CAT, SOD, and POD) antioxidant defense systems. Pre-treatment with IAA prevented the alterations of stress parameters caused by drought, while treatment with IAA alone did not produce changes in TBARS levels, or GSH and AS contents. Moreover, the activities of the classical enzymes involved in the enzymatic defense system (SOD, CAT, and POD) remained similar to control values. Furthermore, this hormone could enhance HO-1 activity (75% with respect to controls), and this increase was positively correlated with protein content as well as gene expression. The direct participation of HO-1 as an antioxidant enzyme was established by performing experiments in the presence of Zn-protoporphyrin IX, a well-known irreversible inhibitor of this enzyme. It was also demonstrated that HO-1 is modulated by NO, as shown by experiments performed in the presence of an NO donor (sodium nitroprusside), an NO scavenger (2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide), or an NO synthesis inhibitor (N-nitro-L-arginine methyl ester, NAME). Discussion: It is concluded that IAA is responsible, at least in part, for the protection against oxidative stress caused by drought in soybean plants through the modulation of NO levels which, in turn, enhances HO-1 synthesis and activity.

“…The result of Meng et al (2011) suggested that exogenous CO could suppress the oxidative damage induced by Hg toxicity via heightening the activities of SOD, CAT and POD. In addition, several studies indicated that heme oxygenase（ HO）widely existing in plants had the oxidation resistance function as well (Santa-Cruz et al, 2010). Exogenous CO might induce the HO gene expression of plant tissue, and then increase HO activity.…”

“…While earlier studies pointed to plant HO as a source of phytochrome chromophore , more recent works showed that HO synthesis increases in soybean plants subjected to oxidative stress conferring resistance to a subsequent insult (Noriega et al 2004;Balestrasse et al 2005). Moreover, we have recently demonstrated that ROS are involved in HO-1 upregulation in soybean leaves subjected to UV-B radiation (Yannarelli et al 2006 andSanta Cruz et al 2010). We hypothesized that NO may also participate in this process, as it regulates the oxidative status and mediates other UV-B responses.…”

“…NO is a reactive nitrogen species and, depending on its concentration, it produces either protective or toxic effects. A low dose of NO modulates superoxide anion formation and inhibits lipid peroxidation, resulting in an antioxidant function during stress (Boveris et al 2000 andSanta Cruz et al 2010). Moreover, microarray studies have shown that NO induces a large number of genes at transcriptional level, among them those of antioxidant enzymes (Parani et al 2004).…”
