“…Recent studies in plants demonstrated that HO contributes to alleviating the effects of salt stress. These studies found that the activity of HO was induced due to oxidative stress under salinity conditions (Zilli et al, 2008(Zilli et al, , 2009Xie et al, 2008Xie et al, , 2011Wei et al, 2013). …”

IntroductionAbiotic stress is a global agricultural issue that limits plant growth and yield. Amongst abiotic stresses, salt stress leads to significant crop losses worldwide (Greenway and Munns, 1980). Although natural salts are present in soil, their increased concentration affects plant growth adversely. Rao et al. (2008) reported that salinity affects about 932 million hectares of land globally. In plant cells under salt stress, Na + and Clions accumulate in cytoplasm and lower the external water potential, resulting in turgor loss (Binzel et al., 1988). It creates an imbalance of cellular ions that results in ion toxicity, or osmotic stress, followed by significant oxidative stress (Gosset et al., 1996;Goemez et al., 1999;Hasegawa et al., 2000). Together, these factors lead to decreased plant growth, development, and survival. Elevated amounts of reactive oxygen species (ROS) such as superoxide (O 2•ˉ) , hydrogen peroxide (H 2 O 2 ), and hydroxyl (OH • ) radicals can critically disturb cellular homeostasis and standard metabolism through oxidative damage to protein, lipids, and nucleic acid (Baxter et al., 2007).Plants elicit a molecular response to prevent oxidative damage due to ROS production and adjust to the oxidative stress (Baxter et al., 2007;Demirkaya, 2014;Yaycılı and Alikamanoğlu, 2012). They have developed a multifaceted antioxidant defense with enzymatic molecules, including ascorbate peroxidase (APX, EC 1.11.1.11), glutathione reductase (GR, E.C. 1.6.4.2), and peroxidase (POD, EC 1.11.1.7). All these molecules play an important role in scavenging ROS formed during oxidative damage (Erdal and Çakırlar, 2014;Petrić et al., 2014).Recently, the role of heme oxygenase (HO, EC 1.14.99.3) has been recognized among plant defenses as a catalyst for the oxidation of heme to biliverdin IXα (BV), CO, and

“…Previous result also postulated that HO-1 in alfalfa mature nodules is involved in leghemoglobin metabolism (Baudouin et al 2004), and the expression of HO-1 is usually triggered by diverse stress-inducing stimuli including salinity stress (Xie et al 2008;Zilli et al 2008;Ling et al 2009), cadmium (Cd) exposure (Noriega et al 2004;Han et al 2008), UV radiation (Yannarelli et al 2006), reactive oxygen species (ROS) such as H 2 O 2 (Yannarelli et al 2006;Chen et al 2009), and nitric oxide (NO) (Noriega et al 2007;Xuan et al 2008;Santa-Cruz et al 2010). Thus, the up-regulation of HO-1 could act as antioxidant barrier against various stresses-induced oxidative damage (Shekhawat and Verma 2010).…”

Cadmium-induced heme oxygenase-1 gene expression is associated with the depletion of glutathione in the roots of Medicago sativa

Following previous findings that cadmium (Cd) induces heme oxygenase-1 (HO1) gene expression in alfalfa seedling roots, we now show that the decreased glutathione (GSH) and ascorbic acid (AsA) contents, induction of HO-1 gene expression and its protein level by Cd was mimicked by a GSH depletor diethylmaleate (DEM). Meanwhile, above Cd- or DEM-induced decreased GSH content followed by HO-1 up-regulation could be strengthened or reversed differentially by the application of a selective inhibitor of GSH biosynthesis L: -buthionine-sulfoximine (BSO), or exogenous GSH and AsA, respectively. The antioxidative behavior of HO-1 induction was further confirmed by histochemical staining for the detection of loss of membrane integrity in a short period of treatment time. Additionally, the induction of HO-1 transcript was inhibited by the transcriptional inhibitor actinomycin D (ActD) or protein synthesis inhibitor cycloheximide (CX, especially). In contrast, the level of HO-2 transcript did not change upon various treatments. Together, above results suggested that Cd-induced up-regulation of HO-1 gene expression is associated with GSH depletion, which is at least existing transcriptional regulation level, thus leading to enhanced antioxidative capability transiently.

“…However, the role of HO regulating LR formation in rice has not been examined. Hemin (Hm), a heme (ferroprotoporphyrin IX) compound, is a potent HO1 inducer (Zilli et al 2008;Fu et al 2011). In this study, we examined the role of HO regulating LR formation in rice, with the effect of Hm on LR formation used as a positive control.…”

Heme oxygenase is involved in nitric oxide- and auxin-induced lateral root formation in rice

Lateral root (LR) development performs the essential tasks of providing water, nutrients, and physical support to plants. Therefore, understanding the regulation of LR development is of agronomic importance. In this study, we examined the effect of nitric oxide (NO), auxin, and hemin (Hm) on LR formation in rice. Treatment with Hm [a highly effective heme oxygenase (HO) inducer], sodium nitroprusside (SNP, an NO donor), or indole-3-butyric acid (IBA, a naturally occurring auxin) induced LR formation and HO activity. LR formation and HO activity induced by SNP and IBA but not Hm was reduced by the specific NO scavenger 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide. As well, Hm, SNP, and IBA could induce OsHO1 mRNA expression. Zn protoporphyrin IX (the specific inhibitor of HO) and hemoglobin (the carbon monoxide/NO scavenger) reduced LR number and HO activity induced by Hm, SNP, and IBA. Our data suggest that HO is required for Hm-, auxin-, and NO-induced LR formation in rice.
