“…In order to achieve this goal, the present study evaluated the phytoaccumulation potential of five native herbaceous plants: Verbascum pulverulentum Vill, Melilotus officinalis (L.) Lam., Echium vulgare L., Stellaria media L., Artemisia vulgaris L. and the phytostabilization potential of two native woody plants: Rhus typhina L. and Populus nigra L. These plants grow in soils polluted with heavy metals without suffering any toxic effects, which is why they were included in this study. Several studies report that some of the above-mentioned plants can accumulate large amounts of heavy metals (Chandra et al 2016;Gajić et al 2018;Jakovljević et al 2019), however, little is known about their ability to accumulate heavy metals when growing around the Zenica steel mill.…”

This study investigates levels of soil pollution and estimates the phytoremediation potential of 7 native plants growing close to the Zenica steel mill. Plant leaves or roots and associated soil samples were collected from this site and characterized in terms of the concentrations of the heavy metals Cr, Cd, Pb, Zn, Cu and Ni. Heavy metal concentrations in soil and plant samples were determined using atomic absorption spectrophotometry. Bioaccumulation factors for heavy metals were also calculated. All plants studied had a low ability to remove or stabilize heavy metals in soil. This was probably associated with the poor mobility and thus poor availability of heavy metals to the plants growing in the vicinity of this steel mill.

“…Depending on the chemical structure of phenolic compounds, they have the ability to electron-donation and radical scavenging, which inhibits the action of reactive oxygen species (ROS) synthesized under metal stress [ 12 ]. Many plant species characterized by a naturally high concentration of phenolic metabolites or unique phenolic composition (ability to the synthesis of some rare phenolic derivatives, e.g., 1,4-naphtoquinones) are capable of sustaining growth on metal-contaminated soil, such as Pontechium maculatum [ 48 ]. In this study we also analyzed the activity of glutathione S-transferase, a key enzyme combining the ability to detoxification and radical scavenging [ 49 , 50 ], to facilitate an understanding of observed plant responses.…”

The study investigated whether short-term priming supports plant defense against complex metal stress and multiple stress (metals and salinity) in halophyte Lobularia maritima (L.) Desv. Plants were pre-treated with ectoine (Ect), nitric oxide donor—sodium nitroprusside (SNP), or hydrogen sulfide donor—GYY4137 for 7 days, and were transferred onto medium containing a mixture of metal ions: Zn, Pb, and Cd. To test the effect of priming agents in multiple stress conditions, shoots were also subjected to low salinity (20 mM NaCl), applied alone, or combined with metals. Hydropriming was a control priming treatment. Stress impact was evaluated on a basis of growth parameters, whereas defense responses were on a basis of the detoxification activity of glutathione S-transferase (GST), radical scavenging activity, and accumulation of thiols and phenolic compounds. Exposure to metals reduced shoot biomass and height but had no impact on the formation of new shoots. Priming with nitric oxide annihilated the toxic effects of metals. It was related to a sharp increase in GST activity, glutathione accumulation, and boosted radical scavenging activity. In NO-treated shoots level of total phenolic compounds (TPC) and flavonoids remained unaffected, in contrast to other metal-treated shoots. Under combined metal stress and salinity, NO and H2S were capable of restoring or improving growth parameters, as they stimulated radical scavenging activity. Ect and H2S did not exert any effect on metal-treated shoots in comparison to hydropriming. The results revealed the stimulatory role of nitric oxide and low doses of NaCl in combating the toxic effects of complex metal stress in L. maritima. Both NO and NaCl interfered with thiol metabolism and antioxidant activity, whereas NaCl also contributed to the accumulation of phenolic compounds.

Pontechium maculatum (Russian bugloss) is a medical plant belonging to the family Boraginaceae. Although this species is known as a medical plant rich in biologically active secondary metabolites, biotechnological studies about this valuable plant is still missing. The scientific objectives of this study were to investigate the biomass production, synthesis, and productivity of various phenolic acids, flavonoids, and shikonin in P. maculatum cultivated in various breeding systems. Additionally, the antioxidant activity of plant-derived extracts was evaluated. Plants were cultivated in a traditional agar-solidified medium, a liquid medium with rotary shaking, and a temporary immersion bioreactors Plantform™ (TIB), as well as cultivated in soil (ex vitro conditions). Analyses of the growth index and dry weight accumulation were performed on the collected material. In the extracts obtained from examined plants, total phenolic content was estimated, and qualitative and quantitative analysis of phenolic derivatives using DAD-HPLC was conducted, simultaneously with an analysis of antioxidant capacity. TIB stimulated the highest synthesis of all examined phenolic acids and shikonin. In TIB-cultivated shoots level of rosmarinic acid obtained a concentration of 3160.76 mg × 100 g− 1 dry weight (DW), and shikonin obtained a concentration of 77.26 mg × 100 g− 1 DW. Furthermore, plants from TIB were characterized by the highest productivity of all studied phenolic derivatives, what makes it very effective platform for the synthesis of biologically active secondary metabolites in Russian bugloss. Moreover, this article shows that P. maculatum is a rich source of various phenolic derivatives with high antioxidant potential.
