“…We provide evidence that the metabolic activity of fullerenol is expressed depending Fe status of plants created either with (+Fe III and +Fe II ) or without (−Fe III and −Fe II ) Fe supply. Previously we demonstrated that the root apoplastic and total Fe contents of the +Fe II cucumber plants were significantly higher as compared with the +Fe III plants [ 22 ]. Ferrous (Fe II ) species are more soluble than Fe III ions.…”

“…It has been reported that a high Fe II concentration in soil solution can cause imbalances in the nutrient uptake [ 52 ]. Although leaf metabolomics pathways of Fe-fed plants were perturbed by different Fe species they, however, did not significantly alter plant dry biomass, chlorophyll (Chl) content, Chl-fluorescence parameters and elemental composition [ 22 ]. Thus, the concentration of Fe II (10 μM) used in this study was probably not toxic, suggesting that metabolomics perturbations observed in the Fe II -fed cucumber were unlikely to be associated with toxicity of ferrous ions.…”

“…Seeds (about 300 pieces) of cucumber were surface-sterilised and germinated between two sheets of filter paper moistened with distilled water at 28°C for four days in the dark. A detailed description of the experimental design has been reported recently [ 22 ]. Briefly, the seedlings were pre-incubated for 7 days in a complete nutrient solution containing (mM): 0.7 K 2 SO 4 , 0.1 KCl, 2.0 Ca(NO 3 ) 2 , 0.5 MgSO 4 , 0.1 KH 2 PO 4 , and (μM): 1.0 MnSO 4 , 1.0 ZnSO 4 , 0.5 CuSO 4 , 0.01 (NH 4 ) 6 Mo 7 O 24 and 10 H 3 BO 3 .…”

“…Most abundant among the identified metabolites were sugars and their derivatives (95), including oligosaccharides: pentoses, hexoses, sugar alcohols, and sugar acids. Furthermore, amino acids (19, among them 12 ones are proteinogenic), carboxylic acids and energy metabolism intermediates (25), fatty acids and their derivatives (22), as well as nitrogenous bases, sterols and other compounds were detected. The results were visualised as a heat map combined with a dendrogram of hierarchical clustering with Spearman's distance (1 − r) (Fig 1).…”

“…Foliar application of fullerenol alleviated drought impact in sugar beets and Fe chlorosis in cucumber [ 20 , 21 ]. Very recently, we found that fullerenol could protect cucumber plants against Fe deficiency through increased utilisation of root apoplastic Fe [ 22 ]. The beneficial effects were more pronounced in Fe II -starved plants, being higher in root apoplastic Fe, suggesting that fullerenol might facilitate Fe transport in plants, depending on their Fe status.…”

The unique properties of carbon-based nanomaterials, including fullerenol, have attracted great interest in agricultural and environmental applications. Iron (Fe) is an essential micronutrient for major metabolic processes, for which a shortage causes chlorosis and reduces the yield of many crops cultivated worldwide. In the current study, the metabolic responses of Cucumis sativus (a Strategy I plant) to fullerenol treatments were investigated depending on the Fe status of plants. Cucumber plants were grown hydroponically, either with [+FeII (ferrous) and +FeIII (ferric)] or in Fe-free (−FeII and −FeIII) nutrient solution, with (+F) or without (−F) a fullerenol supply. Iron species-dependent effects were observed in either Fe-fed or Fe-starved plants, with alteration of metabolites involved in the metabolism of carbohydrates, amino acids, organic acids, lipophilic compounds. Metabolic perturbations triggered by fullerenol in the FeIII-treated plants were in the opposite kind from those in the FeII-treated plants. Whereas in the FeIII-fed plants, fullerenol activated the metabolisation of carbohydrates and amino acids, in the FeII-fed plants, fullerenol activated the metabolisation of lipophilic compounds and repressed the metabolisation of carbohydrates and amino acids. In FeIII-deficient plants, fullerenol stimulated the metabolism of C3 carboxylates and lipophilic compounds while repressing the metabolism of amino acids, hexoses and dicarboxylates, while in FeII-deficient plants, activations of the metabolism of amino acids and dicarboxylates and repression of sterol metabolism by fullerenol were observed. The results indicated that the valence state of Fe sources is of importance for re-programming metabolome responses in cucumber to fullerenol either in Fe-sufficient or Fe-deficient conditions. These investigations are significant for understanding fullerenol interactions and risk assessment in plants with different Fe statuses.
