“…Kovacik et al [ 41 ] found that Ni accumulation in Matricaria chamomilla increased its total phenol and chlorogenic acid content. Han et al [ 44 ] reported that the accumulation of Cd in pumpkin roots increased its superoxide dismutase, peroxidase, and catalase activities to remove reactive oxygen species.…”

“…A wide range of mineral elements are closely related to improving plant stress resistance, i.e., Ca, Sr, B, Mn, Ni, Cu, and Cd. Some studies have shown that they are closely related to the flavonoid composition and its content, the activities of antioxidant-related enzymes, and the cell wall synthesis in plants [ 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. It has been reported that the roles of the above seven mineral elements in plants facilitate plants against adversities [ 38 , 47 , 48 , 49 , 50 , 51 , 52 ].…”

Rhodiolacrenulata (Hook.f. & Thomson) H.Ohba is an alpine medicinal plant that can survive in extreme high altitude environments. However, its changes to extreme high altitude are not yet clear. In this study, the response of Rhodiola crenulata to differences in altitude gradients was investigated through chemical, ICP-MS and metabolomic methods. A targeted study of Rhodiola crenulata growing at three vertical altitudes revealed that the contents of seven elements Ca, Sr, B, Mn, Ni, Cu, and Cd, the phenolic components, the ascorbic acid, the ascorbic acid/dehydroascorbate ratio, and the antioxidant capacity were positively correlated with altitude, while the opposite was true for total ascorbic acid content. Furthermore, 1165 metabolites were identified: flavonoids (200), gallic acids (30), phenylpropanoids (237), amino acids (100), free fatty acids and glycerides (56), nucleotides (60), as well as other metabolites (482). The differential metabolite and biomarker analyses suggested that, with an increasing altitude: (1) the shikimic acid-phenylalanine-phenylpropanoids-flavonoids pathway was enhanced, with phenylpropanoids upregulating biomarkers much more than flavonoids; phenylpropanes and phenylmethanes upregulated, and phenylethanes downregulated; the upregulation of quercetin was especially significant in flavonoids; upregulation of condensed tannins and downregulation of hydrolyzed tannins; upregulation of shikimic acids and amino acids including phenylalanine. (2) significant upregulation of free fatty acids and downregulation of glycerides; and (3) upregulation of adenosine phosphates. Our findings provide new insights on the responses of Rhodiola crenulata to extreme high altitude adversity.

“…Plants can cope with various stresses through glyoxylate and dicarboxylate metabolism pathways (Han et al, 2021; He et al, 2021), it enhanced plant resistance to environmental stresses mainly through the balance of metabolic disturbance and energy transfer (Zhao et al, 2020). Under Cd (Lu et al, 2021), copper (Gao et al, 2022), and arsenic (Patel & Parida, 2022) stresses in plants, the contents of various metabolites in glyoxylate and dicarboxylate metabolism pathways change to cope with heavy metal toxicity.…”

Metabolic profiles in xylem sap are considered a fundamental mechanism for Cadmium (Cd) detoxification in plants. However, the metabolic mechanism of Brassica juncea xylem sap in response to Cd is still unclear. Here, we investigated the effects on the metabolomics of B. juncea xylem sap treated with Cd at different times by utilizing a nontargeted liquid chromatography‐mass spectrometry (LC‐MS)‐based metabolomics method for further elucidating the response mechanism of Cd exposure. The findings indicated that 48 h and 7 days Cd exposure caused significant differences in metabolic profiles of the B. juncea xylem sap. Those differential metabolites are primarily involved in amino acids, organic acids, lipids, and carbohydrates, and most of them were downregulated, which played essential roles in response to Cd stress. Furthermore, B. juncea xylem sap resisted 48‐h Cd exposure via regulation of glycerophospholipid metabolism, carbon metabolism, aminoacyl‐tRNA biosynthesis, glyoxylate and dicarboxylate metabolism, linoleic acid metabolism, C5‐branched dibasic acid metabolism, alpha‐linolenic acid metabolism, cyanoamino acid metabolism, ABC transporters, biosynthesis of amino acids, and pyrimidine metabolism; whereas alpha‐linolenic acid metabolism, glycerophospholipid metabolism, photosynthesis, and oxidative phosphorylation were regulated for resisting 7‐day Cd exposure.

“…To evaluate the similarity among biological replicates and the differences between samples, a correlation heatmap was constructed and a principal component analysis (PCA) and a partial least squares discriminant analysis (PLS-DA) were performed on the basis of the metabolite profiles (Lu et al, 2017). A variable importance in projection (VIP) value >1 and P < 0.05 were set as the criteria for identifying significant differentially abundant metabolites between samples (Lu et al, 2017;Han et al, 2021). Figures for the heatmaps, volcano maps, Venn diagram, and KEGG pathways were obtained using the Majorbio Cloud Platform (www.majorbio.com).…”

Apple scar skin viroid (ASSVd) can infect apple trees and cause scar skin symptoms. However, the associated physiological mechanisms are unclear in young saplings. In this study, ASSVd-infected and control ‘Odysso’ and ‘Tonami’ apple saplings were examined to clarify the effects of ASSVd on apple tree growth and physiological characteristics as well as the leaf metabolome. The results indicated that leaf ASSVd contents increased significantly after grafting and remained high in the second year. Leaf size, tree height, stem diameter, branch length, and leaf photosynthetic efficiency decreased significantly in viroid-infected saplings. In response to the ASSVd infection, the chlorophyll a and b contents decreased significantly in ‘Odysso’, but were unchanged in ‘Tonami’. Moreover, the N, P, K, Fe, Mn, and Ca contents decreased significantly in the leaves of viroid-infected ‘Odysso’ or ‘Tonami’. Similarly, the CAT and POD contents decreased significantly in the viroid-infected saplings, but the SOD content increased in the viroid-infected ‘Tonami’ saplings. A total of 15 and 40 differentially abundant metabolites were respectively identified in the metabolome analyses of ‘Odysso’ and ‘Tonami’ leaves. Specifically, in the viroid-infected ‘Odysso’ and ‘Tonami’ samples, the L-2-aminobutyric acid, 6″-O-malonyldaidzin, and D-xylose contents increased, while the coumarin content decreased. These metabolites are related to the biosynthesis of isoflavonoids and phenylpropanoids as well as the metabolism of carbohydrates and amino acids. These results imply that ASSVd affects apple sapling growth by affecting physiological characteristics and metabolism of apple leaves. The study data may be useful for future investigations on the physiological mechanisms underlying apple tree responses to ASSVd.
