“…The endogenous accumulation of phenolic acids has been reported as a mechanism of plant tolerance of some abiotic stresses, such as toxic metals, in many plant species (Mohammadi et al 2021;Mousavi et al 2021). All phenolic acids and flavonoids measured in this research were significantly increased in the treatments of S 0 TF N and S 0 TF P , which is consistent with high amounts of total flavonoids in these two treatments.…”

The effects of fungi and bacteria biofertilizers under salinity stress were studied on some morphological and physiological traits of quinoa. The experiment was conducted as a factorial based on a completely randomized design with three replications. The factors included NaCl (no salinity-150 mM NaCl and 300 mM NaCl), Trichoderma (no Trichoderma and Trichoderma), and bacterial biofertilizers (no biofertilizer-N biofertilizer and P biofertilizer). The highest shoot and root length and dry weight were observed in the treatment of no salinity + no Trichoderma + N biofertilizer. Salinity increased Na + and K + content and decreased K + /Na + ratio, whereas the application of Trichoderma alleviated the effect of salinity on these factors. Ca 2+ /Na + and Mg 2+ /Na + ratios were significantly decreased in high salinity level compared to the zero salinity level. The highest and lowest phenol content was observed in the treatments of 300 mM NaCl + Trichoderma + P biofertilizer and no salinity + no Trichoderma + N biofertilizer, respectively. Flavonoid content was higher in the treatments of no salinity + Trichoderma + N biofertilizer and no salinity + Trichoderma + P biofertilizer than in the other treatments, also The high-performance liquid chromatography analysis revealed that all phenolic and flavonoid compounds exhibited the greatest increase in treatments of no salinity + Trichoderma + N biofertilizer and no salinity + Trichoderma + P biofertilizer, which is consistent with the significant increase in total flavonoid content in these treatments. The results showed that using N biofertilizer can improve the growth and development of quinoa in saline soils.

Due to the use of various substrates in the production of edible mushrooms which may contain metals, including Cu and Pb, it is important to understand the influence of mutual interactions between them in the process of their accumulation in fruit bodies. For this reason, the effects of Cu, Pb, and Cu × Pb on yield, accumulation of five major elements (Ca, K, Mg, Na and P), trace elements (Cu, Pb and Fe) and some bioactive compounds in Lentinula edodes fruit bodies were studied. Both the metals were added in doses of 0.1 and 0.5 mM (Cu0.1, Cu0.5, Pb0.1, Pb0.5 and their combinations). The addition of the metals resulted in a reduction in size, amount and finally yield of fruit bodies. Depending on the presence of Cu and or Pb and their concentration in the substrate, both antagonism and synergism may occur. The influence on the accumulation of other determining elements was also recorded. Among phenolic compounds, phenolic acids and flavonoids were detected. 2,5-Dihydroxybenzoic acid dominated in fruit bodies in the control variant, Pb0.1, Pb0.5 and all experimental variants enriched with Cu + Pb, while gallic acid was the major phenolic after Cu0.1 and Cu0.5 addition. Only protocatechuic acid content increased in all combinations. A significant decrease of all aliphatic acid contents in comparison to the control variant was observed in the Cu0.1 and Pb0.1 variants. Significant stimulation of aliphatic acid synthesis was recorded in Cu0.5 and Pb0.5 variants and in the mixture of both the metals. The additions pointed to the possible role of the determined molecules in detoxification mechanisms.

“…The release of phenolic compounds is caused by the over-expression of the biosynthesis of phehylpropanoid enzymes route. 15 This is brought about by heavy metals via upregulating the functions of key biosynthetic enzymes such as Shikimate dehydrogenase, glucose-6-phosphate dehydrogenase, and cinnamyl alcohol dehydrogenase. 61 There are other studies that have successfully demonstrated the ability of vetiver grass to tolerate heavy metals, acidity, salty soils, and agrochemicals.…”

“…63 However chelating metal ions expose plants to toxic metal stress which triggers the plant to produce more of certain components including phenolic components. 15,53 Therefore, this indicates the intensification of heavy metal stress to plants upon application of soil amendments such as EDTA that chelate heavy metals and make them easily adsorbed into plant tissues. The heavy metals stress was strengthened by increased bioavailability of heavy metals as a result of application of EDTA leading to production of secondary metabolites such as essential oils as a defence mechanism to survive the heavy metals stress.…”

Background/Objective: Vetiver grass (Vetiveria zizanioides (L.) Nash. Syn. Chrysopogon zizanioides (L.) Roberty; family Poaceae) is well-known for producing essential oil that is commonly used in premier perfumery, food, and pharmaceutical industries. The quality of essential oil produced should be assessed before application in production of various products. Methods/Results: In this study, the yield of essential oil extracted from vetiver grass found in Botswana was assessed after cultivation in mine tailings. The respective influence of chelating agents and microbes such as ethylene diamine tetra-acetic acid (EDTA) and arbuscular mycorrhizal fungi (AMF) on the yield of essential oils was also evaluated. Results obtained showed that vetiver grass grown in mine tailings produced more essential oils compared to unpolluted soils. Vetiver grass grown on sterilized soils yielded only 0.26% of essential oils compared to 0.86% of that cultivated in mine tailings. Furthermore, essential oil yield was increased in soil amended with EDTA (0.95%) and after inoculation with AMF (0.89%). Addition of EDTA and AMF enhanced the uptake of heavy metals by vetiver grass and increased heavy metal stress and thereby making vetiver grass release secondary metabolites in the form of essential oils. It is important to note that even though the mine tailings accumulated high concentrations of heavy metals (As: 47.31 ± 1.40, Cu: 1632.24 ± 38.20, Mn: 402.68 ± 18.21, Ni: 728.26 ± 46.20, Pb: 41.26 ± 5.38, and Zn: 103.97 ± 5.34), very low concentrations of metals were detected in essential oils extracts. Conclusion: This study indicates the ability of vetiver grass to produce more essential oil under heavy metal stress making it useful for both essential oil production and important candidate for phytoremediation.
