“…MDA content in the spinach variety Japanese big leaf increased with 800 mg L −1 of CuSO 4 , but the mentioned concentration and higher did not terminate plant development [ 67 ]. Thus, MDA concentration did not differ in carrots given a maximum of 400 mg kg −1 of pure Copper(II) nitrate trihydrate (Cu(NO 3 ) 2 3H 2 O) [ 68 ]. These remarks, along with this work utilizing lower copper concentrations, clearly suggest that MDA, such as H 2 O 2 , can operate as a signal molecule.…”

Atemoya (Annona × atemoya Mabb.), a climacteric fruit of the Annonaceae family, is becoming increasingly popular due to its organoleptic and nutritional properties. Anthracnose, a fungus of the Colletotrichum genus, is one of the most serious diseases in orchards, causing significant damage if not controlled, so producers use phytosanitary products. The current study sought to investigate the quality of atemoya fruits after harvest in an orchard with anthracnose controlled by Cu(OH)2 application: T1—no Cu(OH)2, T2—7.8 mL Cu(OH)2 L1 divided into two applications, T3—15.6 mL Cu(OH)2 L1 divided into four, T4—8.0 mL Cu(OH)2 L1 divided into eight, and T5—13.0 mL Cu(OH)2 L1 divided into thirteen applications. The sugar profile of fruits was examined, as well as MDA, H2O2, and quality parameters such as pH, mass, soluble solids, titratable acidity, and maturation index. MDA, such as H2O2, can function as a signal molecule. Eight applications of 1.0 mL L-1 Cu(OH)2 resulted in increased concentrations of H2O2 and MDA, signal molecules involved in sugar modification profiles such as glucose, fructose, and trehalose. It also had a high titratable acidity, a lower maturation index, better fruit quality, and a longer shelf life.

BackgroundCadmium (Cd) poses threats to human health by affecting the safety (Cd accumulation) and quantity (contents of active ingredients) of Salvia miltiorrhiza due to human activities and Cd characteristics. It remains largely unknown how Cd stress affects the synthesis of active ingredients in S. miltiorrhiza. ResultsHere we investigated physiologies (contents of Cd, malondialdehyde (MDA) and proline, and activities of superoxide dismutase, peroxidase (POD) and catalase (CAT)), transfer factor (TF), bioconcentration factor (BCF) and metabolites of S. miltiorrhiza at different levels of Cd contamination with a pot experiment. The results revealed that Cd concentration, as it rose in soil, increased significantly in roots and leaves with TFs and BCFs below 1 in the Cd addition groups; POD and CAT activities and proline content increased and then declined significantly. Besides, amino acids and organic acids (especially D-glutamine (D-Gln), L-aspartic acid (L-Asp), L-phenylalanine (L-Phe), L-tyrosine (L-Try), geranylgeranyl-PP (GGPP), and rosmarinic acid (RA)) contributed more than other metabolites in discriminating roots under different levels of Cd contamination. With Cd concentration rising, the relative content of GGPP declined and then increased significantly; RA content rose significantly; content of L-Phe and L-Try increased and then declined significantly, while the content of D-Gln and L-Try decreased and then increased significantly. Conclusions These results suggested that S. miltiorrhiza belonged to a non-Cd-hyperaccumulator with most Cd accumulated in roots; Cd enhanced the RA synthesis via regulating amino acid metabolism but inhibited the tanshinone synthesis mainly by declining the GGPP content, with proline, POD and CAT playing vital roles in resisting Cd stress.

“…In a prior study, under high Cd concentrations, SOD activity was significantly lower than that of a control, whereas POD activity was higher than that of the control [23]. Rusin et al [24] observed that plants growing on diesel-contaminated soil were characterized by lower SOD activity but higher POD activity and proline levels.…”

The soil pollution caused by diesel oil and heavy metals has become an increasingly serious environmental issue, with negative global-scale impacts. The remediation of contaminated soil requires special attention, in which phytoremediation has emerged as an ecofriendly solution. However, the response of plants to the combined stress of diesel oil and heavy metals remains largely unknown. In this study, the aim was to investigate the potential of Populus alba and P. russkii for phytoremediation by examining their response to combined diesel oil and heavy metal stress. In a greenhouse experiment using soil contaminated with 15 mg kg−1 of diesel oil and varying concentrations of Sr (0, 10, or 100 mg kg−1), we studied the physiological and biochemical changes, as well as the Sr absorption, of P. alba and P. russkii. The results showed that at high concentrations of Sr and diesel oil, the growth of both species was substantially inhibited, but P. alba exhibited higher resistance due to its higher antioxidant enzyme activities and increased accumulation of soluble sugar and proline. Additionally, P. alba concentrated Sr in the stem, whereas P. russkii accumulated Sr in the leaf, exacerbating its negative effects. Diesel oil treatments were beneficial for Sr extraction due to cross-tolerance. Our findings indicate that P. alba is more suitable for the phytoremediation of Sr contamination due to its superior tolerance to combined stress, and we identified potential biomarkers for monitoring pollution. Therefore, this study provides a theoretical basis and implementation strategy for the remediation of soil contaminated by both heavy metals and diesel oil.
