“…In this study, a positive correlation between TPC and Mn concentration was observed in leaves ( r = 0.75, p = 0.005) and stems ( r = 0.91, p = 0.000), as well as between total phenolic quantity (TPQ) and Mn in the whole plant ( r = 0.65, p = 0.022; Table 2 ). Despite the fact that Mn is associated with an increase in the concentration of biophenols [ 22 , 23 , 24 , 25 ], several studies reported possible negative effects of Mn fertilisers on the total amount of biophenols in roots and leaves [ 43 ]. In our experiment, the TPC values remained unaltered in all of the plant parts, but were generally higher in leaves compared to the other tissues.…”

“…Similarly, the total phenolic content (TPC) in tomato fruit increased when the plant was exposed to higher Mn concentrations [ 22 ]. Increased concentrations of flavonoids in water mint were linked to higher Mn concentration in nutrient solution [ 23 ]. According to Farzadfar et al [ 24 ], the levels of individual biophenolics in feverfew plants were highly dependent on Mn supply, and the increment in their concentration was proportional to the amount of Mn applied.…”

Manganese (Mn) is an essential element that intervenes in several plant metabolic processes. The olive tree, and its fruits and leaves, are known as a source of nutraceuticals since they are rich in biophenols. However, there is still a serious lack of data about biophenolic distribution in olive stems and roots under Mn fertilisation. In this context, our study aimed to examine the effects of Mn fertilisation on the biophenolic profile in the leaves, stems, and roots of the ‘Istarska bjelica’ olive cultivar. The experiment was set up in a greenhouse, during a period of five months, as a random block design consisting of three treatments with varying Mn concentrations in full-strength Hoagland’s nutrient solution (0.2 µM Mn, 12 µM Mn, and 24 µM Mn). The obtained results indicate that the amount of Mn in the examined olive plant tissues was significantly higher under 12 µM Mn and 24 µM Mn treatments compared to that of the 0.2 µM Mn treatment. While the concentration of biophenols varied in roots depending on the compound in question, a strong positive impact of the increased Mn concentration in nutrient solution (12 µM Mn and 24 µM Mn) on the concentrations of the main biophenolic compounds was observed in stems. The concentration of oleuropein in leaves almost doubled at 24 µM Mn, with the highest Mn concentration, as compared to the 0.2 µM Mn treatment. The obtained results led to the conclusion that the supply of Mn could enhance the concentration of some biologically active compounds in olives grown hydroponically, implying a critical need for further investigation of Mn fertilisation practices in the conventional olive farming system.

“…In one study, different concentrations of this mineral were supplied to samples of Mentha aquatica . This addition to the concentration of manganese increased the secondary metabolite abundance and the total superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX) activities ( 38 ). The manganese values were significantly different among the three samples in this study.…”

Effect of Different Extraction Methods and Geographical Origins on the Total Phenolic Yield, Composition, and Antimicrobial Activity of Sugarcane Bagasse Extracts

Several parameters, including particle size, solvent, temperature, and extraction method, affect phenolic compounds' extraction yield from a plant matrix. Considering the wide availability of sugarcane bagasse (SCB), this study analyzed the effect of different extraction methods and geographical origins on the yield, quality, and antimicrobial activity of phenolic compounds from SCB extracts. Samples from three geographical locations (Veracruz, Mexico; Santa Rosa, Texas, USA; and St. Mary, Louisiana, USA) were analyzed. Extraction was performed using an orbital shaker or ultrasonic bath at various times at a fixed temperature of 50°C, with 90% ethanol or methanol. The highest yield (5.91 mg GAE) was obtained using an orbital shaker for 24 h with 90% methanol as the solvent. HPLC-MS identified desferrioxamine b, baicalein, madecassic acid, and podototarin at different concentrations in all three SCB samples. The antimicrobial activity of these compounds was tested against Escherichia coli K12, Bacillus cereus, Enterobacter aerogenes, Streptococcus aureus, and Enterobacter cloacae. The antimicrobial activity was also tested against modifications of the Saccharomyces cerevisiae: the MutL Homolog 1 (MLH1), Slow Growth Suppressor (SGS1), O-6-MethylGuanine-DNA methyltransferase (MGT1), and RADiation sensitive (RAD14), carrying mutations related to different cancer types. In addition, the results were compared with the effect of ampicillin and kanamycin. The SCB extracts showed up to 90% growth inhibition against B. cereus at 200–800 μg/mL and 50% growth inhibition against S. aureus at 800 μg/mL. The inhibitory effect against modified yeast SGS1, RAD14, and MLH1 was 50–80% at 800 μg/mL. The percentage of inhibition and the phenolic compound contents differed depending on the origin of the SCB sample. These findings are promising for using this industrial byproduct to obtain compounds for nutraceutical, food additive, or medical uses.

“…guianensis and in leaves of B. decumbens in RAA2-grown plants (Tables 3, 4). The thresholds for Mn toxicity in animals and plants are not well defined, but some reports show that plants can accumulate more than 300 µg g −1 without showing phytotoxic symptoms (Nazari et al 2018). Moreover, the CF values for Mn are classified as moderate or even low (Table 3, 4,5), and so, we consider that the values found in this study are not of concern.…”

Metallic elements in plants: bioaccumulation, phytoremediation potential and physiological responses

Pollution caused by metallic elements in the environment is becoming increasingly problematic worldwide. In the current work, several aspects of the metallic elements in plants were investigated, including the accumulation in species affected by an environmental disaster involving the disruption of a mining tailing dam; the physiological responses and phytoremediation potential of the aquatic macrophyte water lettuce (Pistia stratiotes) subjected to excess iron (Fe) and manganese (Mn), and combinations of Fe, Mn, and arsenic (As); and, finally, the in vivo monitoring of As-induced responses in Arabidopsis thaliana plants. We found a concerning enrichment of metal accumulation, especially for Fe and Mn, in the plant species evaluated in affected areas by mining tailings. Considering the spreading potential of contamination in aquatic environments, water lettuce plants, which are often used in phytoremediation studies, were tested for removal of excess Fe and Mn, along with the association with As. The plants displayed a great accumulation of Fe, mainly trapped in roots, whereas Mn was hyperaccumulated in shoots and roots. Accumulation of Mn was observed especially in the apoplast, avoiding major impairments of physiological processes. In presence of As, the plants displayed root loss as an acclimation response, followed by re-emission of the organs. Nonetheless, the specimens were able to maintain a high accumulation of the pollutants, supplied isolated or in association, demonstrating phytoremediation potential in multi- contaminated environments. Furthermore, the in vivo measurements using genetically-encoded biosensors showed intriguing stability of Mg-ATP 2− levels upon short-term arsenate (AsV) exposure. We also observed that the depletion of the GSH pool is the most likely cause of glutathione redox potential (E GSH ) oxidation. The findings presented here emphasize the importance of continuing to monitor metal-contaminated areas, as well as exposing alternatives for phytoremediation of aquatic environments and providing new insights into plant metabolism in response to pollutants. Keywords: Aquatic plants – Pollution effect. Aquatic plants – Heavy metal effects. Pistia stratiotes. Heavy metals. Aquatic plants – Metabolism.
