“…It has also been reported that the level of H 2 O 2 increases following exposure to elevated temperatures, leading to HSF activation and HSP accumulation in Arabidopsis, tobacco (Nicotiana tabacum), and bacteria (Clostridium acetobutylicum; Volkov et al, 2006;Königshofer et al, 2008;Banti et al, 2010). In contrast, peroxide scavengers and inhibitors of H 2 O 2 generation have been shown to reduce HSP expression in HS-exposed Arabidopsis and tobacco, respectively (Volkov et al, 2006;Königshofer et al, 2008 (Delledonne et al, 1998;Murgia et al, 2004;Zago et al, 2006;Wilkins et al, 2011), antioxidant reactions , heavy metal resistance (González et al, 2012), and adventitious root formation (Bai et al, 2012). Proteomic analysis uncovered cross talk between NO and H 2 O 2 in citrus plants (Tanou et al, 2010).…”
