Enantioselective effects of imazethapyr on the secondary metabolites and nutritional value of wheat seedlings

Effect of Pyrazosulfuron-Methyl on the Photosynthetic Characteristics and Antioxidant Systems of Foxtail Millet

“…Under halosulfuron-methyl stress, the SOD, POD, APX, and GR activities of soybean increased (Li et al, 2020), and the SOD and POD activities of foxtail millet leaves also increased but under broad sigma stress (Huang et al, 2015). Bao (2020) found that the antioxidant system of wheat seedlings responded strongly to imazethapyr, specifically, the activities of SOD, CAT, and GPX enzymes were all significantly induced. Hassan and Nemat Alla (2020) reported that a malfunction to the defense system was induced in wheat by isoproturon resulting in inhibitions in GSH-associated enzymes, and the magnitude of inhibition was most pronounced in GPX followed by γ-glutamyl-cysteine synthetase, glutathione synthetase, glutathione S-transferase, and GR.…”

“…The MDA content can reflect the degree of damage to the plant cell membrane and ROS. Under herbicide stress, the MDA content of maize (Panfili et al, 2019), wheat (Bao, 2020), and soybean (Li et al, 2020) was significantly increased. These results showed a significant increase in MDA concentration of foxtail millet under ≥30 g ai ha −1 pyrazosulfuron-methyl treatment, which indicated that the cell integrity of the foxtail millet leaves was compromised; however, with the progress of the fertility process, pyrazosulfuron-methyl at low doses (≤60 g ai ha −1 ) had a certain degree of relief on membrane damage, while there was no obvious recovery under 120 g ai ha −1 pyrazosulfuron-methyl treatment.…”

“…Nemat Alla and Hassan (2014) found that the isoproturon can significantly decrease the contents of GSH and AsA. Under imazethapyr stress, the GSH content of wheat initially increased but then decreased Bao (2020). Wang H. C. et al (2018) reported that bispyribac-sodium caused the perturbation of glutathione homeostasis in rice, including the decreased reduced glutathione (GSH) and increased oxidized glutathione (GSSG).…”

The need to change the approach to the safe use of herbicides by developing chiral and environmentally friendly formulations: a series of enantioselective (R)- and (S)-phenylethylammonium chloroacetates

“…2,45,46 In further studies, the authors also showed that chiral herbicides stereospecifically affected the secondary metabolism and nutritional value of crops. 47 In the case of spring barley, the toxicity of (R)-enantiomers increases with the number of chlorine atoms in the acetate anion, in the order (R)-MCA < (R)-DCA < (R)-TCA (Fig. 5 and Table 2).…”

Effects of tetracycline on the secondary metabolites and nutritional value of oilseed rape (Brassica napus L.)

“…Dietary ber can decrease the risk of a human developing several chronic diseases, including cardiovascular disease and some cancers (Dahl &Stewart 2015). Sugar molecules act as nutrients and also regulate metabolism, growth, stress responses, and development (from embryogenesis to senescence) (Rolland &Sheen 2005).Sugars can participate in the defense responses of a plant stressed by adverse environmental conditions such as drought, cold, and high salinity (Gupta &Kaur 2005).Soluble sugars are alsoimportant to both the nutritional quality (Lin et al 2013) and the taste (Chen et al 2016) of a crop.Plant growth is also controlled by the amounts of nutrients, particularly essential trace elements.The contents of trace elements are low, but they are vital (Jordi et al 2012).A de ciency or surplus of a trace element can cause an imbalance between nutrients and may lead to toxic effects (Chen et al 2015).Some trace elements can alsointerfere with metabolism (Bao et al 2021). It has previously been found that herbicides can induce up-or down-regulation of genes involved in nutrient transport (Chen et al 2015).Also, Previous studies have shown that the Ca, Mg, K, and N contents in bean plants were decreased on exposure to antibiotics (Batchelder 1982).…”
