Exogenous Nitric Oxide Improves the Protective Effects of TiO2 Nanoparticles on Growth, Antioxidant System, and Photosynthetic Performance of Wheat Seedlings Under Drought Stress

“…Moreover, a recent study revealed that exogenous NO may induce the synthesis of endogenous NO which can act as signaling molecule and enhance the antioxidant capacity of cells under stress conditions (Chen et al 2018). NO and TiO 2 NPs as potential ROS scavengers may directly react with oxygen species and oxidize/ reduce O 2 − /O 2 •to O 2 /H 2 O 2 by increasing consumption of oxygen in mitochondrial respiratory chain (Amini et al 2017;Siddiqui et al 2017). It was also reported that NO and TiO 2 NPs may indirectly promote antioxidant system through up-regulating the expression of antioxidant enzymes which leads to enhanced activities of these enzymes, thereby improving plant tolerance against oxidative stress (Amini et al 2017;Tumburu et al 2015;Wu et al 2017).…”

More recently, alleviation of oxidative stress via improving the activities of antioxidant enzymes such as SOD, CAT, and APX have been reported by application of NO and TiO 2 NPs (Amini et al 2017;Khan 2016;Mohammadi et al 2016;Tripathi et al 2017a, b;Siddiqui et al 2017;Yan et al 2016).…”

“…However, foliar application of SNP in presence of TiO 2 NPs reduced the level of oxidative stress and lipid peroxidation under water stress as reflected by significant decreases in H 2 O 2 and MDA contents. NO and TiO 2 NPs can decrease H 2 O 2 and MDA contents under water stress by scavenging H 2 O 2 (Wu et al 2017), activating H 2 O 2 metabolizing enzymes (Baiazidi-Aghdam et al 2016;Khan et al 2017b;Tripathi et al 2017a, b), and improving membrane integrity (Amini et al 2017;Farooq et al 2017;Khan 2016;Mohammadi et al 2016;Tripathi et al 2017a, b). Protective effects of NO and TiO 2 NPs against oxidative stress induced by accumulation of H 2 O 2 and MDA are reported in previous studies (Baiazidi-Aghdam et al 2016;Farooq et al 2017;Khan et al 2017b;Mohammadi et al 2016;Tripathi et al 2017a, b;Wu et al 2017;Yan et al 2016).…”

“…TiO 2 nanoparticles could alleviate harmful effects of drought stress on plant physiological processes by decreasing the levels of MDA and H 2 O 2 and stabilizing photosynthetic pigments (Baiazidi-Aghdam et al 2016). TiO 2 NPs are involved in signal transduction, defense, metabolism, and regulatory processes under stress condition (Amini et al 2017). It was reported that nano-TiO 2 improved growth, yield, and quality of tomato fruits under salt stress by enhancing the activities of antioxidant enzymes such as SOD and POX (Khan 2016).…”

cDNA-AFLP analysis of transcript derived fragments during seed development in castor bean (Ricinus communis L.)

“…This method is an attractive technique for gene discovery on the basis of fragment detection and for temporal quantitative gene expression analysis [9]. From its establishment to the present time, this technology has been used in many plant species, including Arabidopsis thaliana [11], Vitis vinifera [12], Cicer arietinum L. [13] and Robinia pseudoacacia L. [14].…”
