Although H2O2 is known to act as a signaling molecule, activating multiple defense responses that reinforce resistance to various environmental stresses Afatinib research buy in plants (Petrov and Van Breusegem, 2012), very little is known about the mechanisms by which plants perceive/sense H2O2 and how this sensing mechanism is coordinated within the developmental program of a plant. In this review, we summarize our current understanding of the possible mechanisms associated with H2O2-induced enhanced abiotic stress tolerance with special reference to ROS detoxifying/scavenging proteins and gene expression. Exogenous H2O2 and Abiotic Stress Tolerance Many recent studies on plants have demonstrated that H2O2 is a key player in the signal transduction process associated with tolerance to abiotic and biotic stresses, PDGFRA and the induction of the stress cross-tolerance phenomena often observed in plants. A number of reports, discussed in more detail below, have shown that exogenous application of H2O2 can induce tolerance to salinity, drought, chilling, and high temperatures, and heavy metal stress, all of which cause elevated H2O2 production (Gong et al., 2001; Uchida et al., 2002; Azevedo-Neto et al., 2005; Chao et al., 2009; Liu et al., 2010a; Wang et al., 2010a, 2014a; Ishibashi et al., 2011; Gondim et al., 2012, 2013; Hossain and Dasatinib mw Fujita, 2013). Exogenous H2O2 and Salt Stress Tolerance The salt stress-induced oxidative burst due to uncontrolled ROS accumulation has been well documented in plants. However, several recent studies on plants have demonstrated that pre-treatment with exogenous H2O2 can induce salt tolerance. Uchida et al. (2002) studied the effects of H2O2 and nitric oxide (NO) pre-treatments on oxidative stress in rice (Oryza sativa) plants under salt or heat stress. Their results showed that seedlings treated with low concentrations (
