“…Root growth, metabolism and energy change can directly affect the growth of the plant part above ground [26]. Phthalates have oxidative stress effect on plants, the activity of superoxide dismutase, catalase, peroxidase, the content of malondialdehyde and proline have changed after being polluted by DBP [7,27]. Reduced root activity may be caused by the formation of superfluous peroxide and oxygen free radical which damage the cell membrane structure.…”

“…The fresh weight, leaf length, root length and root number were recorded using a plant analyzer (EPSON PerfectionV700 Photo, SilverFast STD4800). The content of chlorophyll a, the activities of SOD/POD and content of MDA were analyzed using a TU-1901 spectrophotometer, as described previously47. The concentration of lipid peroxides was quantified in terms of the MDA concentration.…”

Graphene oxide (GO) is widely used in various fields and is considered to be relatively biocompatible. Herein, “indirect” nanotoxicity is first defined as toxic amplification of toxicants or pollutants by nanomaterials. This work revealed that GO greatly amplifies the phytotoxicity of arsenic (As), a widespread contaminant, in wheat, for example, causing a decrease in biomass and root numbers and increasing oxidative stress, which are thought to be regulated by its metabolisms. Compared with As or GO alone, GO combined with As inhibited the metabolism of carbohydrates, enhanced amino acid and secondary metabolism and disrupted fatty acid metabolism and the urea cycle. GO also triggered damage to cellular structures and electrolyte leakage and enhanced the uptake of GO and As. Co-transport of GO-loading As and transformation of As(V) to high-toxicity As(III) by GO were observed. The generation of dimethylarsinate, produced from the detoxification of inorganic As, was inhibited by GO in plants. GO also regulated phosphate transporter gene expression and arsenate reductase activity to influence the uptake and transformation of As, respectively. Moreover, the above effects of GO were concentration dependent. Given the widespread exposure to As in agriculture, the indirect nanotoxicity of GO should be carefully considered in food safety.

“…In the present study, SOD was observed to increase in shoots, while it decreased in the roots under DBP stress. Cheng and Cheng (2012) reported similar results for the activity of SOD in Spirodela polyrhiza under the exposure of diethyl phthalate (DEP) for 7 d and the decline ranges from 22 to 28 %. They reported that the decrease in activity was due to the down-regulation of all isoenzymes of SOD.…”

Di-n-butyl phthalate (DBP) is one of the frequently detected phthalates in environmental samples. The effects of phthalates are extensively studied in the animals but the effects on plants are scarce. Therefore, the present study is aimed to envisage the effects of DBP on the antioxidative defense system in Hordeum vulgare L. seedlings grown under laboratory conditions for 7 d. The activities of different antioxidative enzymes were enhanced in the shoots. In the roots, the activity of guaiacol peroxidase increased and the catalase activity decreased initially but increased at higher DBP concentrations, whereas the activities of superoxide dismutase, ascorbate peroxidase, and glutathione reductase declined. Furthermore, the content of polyphenols elevated after exposure of seedlings to DBP. The possible reason for these responses of barley seedlings is the oxidative burst, i.e., enhanced production of reactive oxygen species, which were confirmed using confocal microscopy in terms of loss in plasma membrane integrity. DBP also disturbed the normal stomatal morphology of barley seedlings. The study may help to provide insights into the defense of crop plants against phthalate stress.
