“…P provides anion equivalents and is responsible for the charge balance in plants, especially those that are salt‐stressed. In accord with results previously reported, we found that excess nitrate led to a decrease in P concentrations that might have been related to the high level of

{NO}_{3}^{-}

. Likewise, concentrations of P were increased in MT‐HN plants in parallel with a decline in

{NO}_{3}^{-}

levels.…”

In China, excessive use of nitrogen fertilizers in glasshouses leads to nitrate accumulations in soil and plants, which then limits productivity. Melatonin, an evolutionarily highly conserved molecule, has a wide range of functions in plants. We analyzed the effects of melatonin pretreatment on the growth, mineral nutrition, and nitrogen metabolism in cucumber (Cucumis sativus L. "Jin You No. 1") when seedlings were exposed to nitrate stress. An application of 0.1 mmol/L melatonin significantly improved the growth of plants and reduced their susceptibility to damage due to high nitrate levels (0.6 mol/L) during the ensuing period of stress treatment. Although excess nitrate led to an increase in the concentrations of nitrogen, potassium, and calcium, as well as a decrease in levels of phosphorus and magnesium, exogenous melatonin generally had the opposite effect except for a further rise in calcium concentrations. Pretreatment also significantly reduced the accumulations of nitrate nitrogen and ammonium nitrogen and enhanced the activities of enzymes involved in nitrogen metabolism. Expression of Cs-NR and Cs-GOGAT, two genes that function in that metabolism, was greatly down-regulated when plants were exposed to 0.6 mol/L nitrate, but was up-regulated in plants that had received the 0.1 mmol/L melatonin pretreatment. Our results are the first evidence that melatonin has an important role in modulating the composition of mineral elements and nitrogen metabolism, thereby alleviating the inhibitory effect on growth normally associated with nitrate stress.

“…The reason for neutralization in loss of Fe and other microelements may be attributed to the role of Br in regulating or keeping ion homeostasis in pants with or without heavy metal stress. For example, Br24 could keep cell normal metabolism, restore ATP content and maintain ion balance (K, P, Na, Mg, Cl, Fe and Mn) in cucumber plants (Yuan et al, 2015). Br significantly enhanced content of chlorophyll, protein and monosaccharides and number of cells of Chlorella vulgaris under Cd, Pb and Cu stress (Bajguz, 2011).…”

Se (Se(IV) or Se(VI)) for 2 weeks. Then seedlings with or without IP induction (60 mg Fe 2+ L -1 for 3 days) were exposed to 5 mg L -1 hexavalent chromium [Cr(VI)] for 1 week. The results showed that Cr reduced Fe accumulation and uptake by yellow flag with or without IP; however, this effect was significantly neutralized by Br, but not by Se. IP significantly enhanced Cr accumulation in DCB extract and the whole yellow flag seedling, and increased Cr content by 36%. Br24 and Br28 significantly enhanced Cr accumulation and uptake by yellow flag and increased Cr enrichment by 36 and 51% in the absence of IP, and 7 and 21% in the presence of IP, respectively. Se(IV) markedly improved Cr accumulation in the root, but Cr accumulation and uptake in the shoot and DCB extract were not affected by Se(IV) and Se(VI). Our study suggests that Br24 and Br28 can alleviate Fe loss caused by Cr stress and increase Cr accumulation and uptake by yellow flag seedlings.
