“…Moreover, our outcomes indicate that exogenously applied GSNO increases the activity of antioxidants CAT and APX ( Figure 3 e,f) which might help to scavenge ROS to produce water molecules. Our results further confirmed the findings in heavy metal-stressed soybean, wheat, and tomato plants [ 10 , 14 , 23 ]. Taken together, antioxidants were boosted profoundly, which were assigned to the mitigation behavior of GSNO against lead-induced oxidative damage in soybean plants.…”

Heavy metal toxicity, including lead (Pb) toxicity, is increasing in soils, and heavy metals are considered to be toxic in small amounts. Pb contamination is mainly caused by industrialization (e.g., smelting and mining), agricultural practices (e.g., sewage sludge and pests), and urban practices (e.g., lead paint). An excessive concentration of Pb can seriously damage and threaten crop growth. Furthermore, Pb adversely affects plant growth and development by affecting the photosystem, cell membrane integrity, and excessive production of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2) and superoxide (O2−). Nitric oxide (NO) is produced via enzymatic and non-enzymatic antioxidants to scavenge ROS and lipid peroxidation substrates to protect cells from oxidative damage. Thus, NO improves ion homeostasis and confers resistance to metal stress. In the present study, we investigated the effect of exogenously applied NO and S-nitrosoglutathione in soybean plants Our results demonstrated that exogenously applied NO aids in better growth under lead stress due to its ability in sensing, signaling, and stress tolerance in plants under heavy metal stress along with lead stress. In addition, our results showed that S-nitrosoglutathione (GSNO) has a positive effect on soybean seedling growth under lead-induced toxicity and that NO supplementation helps to reduce chlorophyll maturation and relative water content in leaves and roots following strong bursts under lead stress. GSNO supplementation (200 µM and 100 µM) reduced compaction and approximated the oxidative damage of MDA, proline, and H2O2. Moreover, under plant stress, GSNO application was found to relieve the oxidative damage by reactive oxygen species (ROS) scavenging. Additionally, modulation of NO and phytochelatins (PCS) after prolonged metal reversing GSNO application confirmed detoxification of ROS induced by the toxic metal lead in soybean. In summary, the detoxification of ROS caused by toxic metal concentrations in soybean is confirmed by using NO, PCS, and traditionally sustained concentrations of metal reversing GSNO application.

“…43,44 Consequently, numerous previous studies have observed that Mn or Zn compete with Cd for uptake by root tissues, and soil amendments of ZnSO 4 or MnSO 4 have been demonstrated to effectively reduce Cd accumulation in rice and wheat grain. [45][46][47] It is therefore possible that foliarapplied Fe NMs could reduce Cd uptake in wheat by Environmental Science: Nano Paper inhibiting the expression of Cd/Mn transporter genes. In the current study, as the concentration of Cd in the grains decreased, the concentrations of Mn and Zn in wheat grain also decreased from 82.5 mg kg −1 to 50.5 mg kg −1 and from 61.5 mg kg −1 to 41.6 mg kg −1 , respectively (Fig.…”

“…In addition, some ABC transmembrane transport proteins can also facilitate the e ux of certain intracellular heavy metals. Studies have shown that multiple encoding genes such as abcBCG, cupRAC, atmA, merAPTR, mntABC, copAC, cusABRF, pcoBD, and czcBD are involved in various processes of heavy metal e ux [12][13][14]. However, whether these ABC transporters expel chromates remains to be determined.…”

Cellulomonas fimi Clb-11 can reduce high toxic Cr (VI) to low toxic Cr (III). In this study, transcriptomics was used to analyze the key genes, which was involved in Cr (VI) uptake and reduction in C. fimi Clb-11. The results showed that when C. fimi Clb-11 was subjected to 0.5 mM Cr (VI) stress, 654 genes were upregulated. Among them, phosphate transport protein encoding gene phoU, inorganic phosphate transport protein encoding gene TC.PIT, and molybdate transport protein encoding genes modA, modB, and modC were involved in the passive uptake of Cr (VI) by C. fimi Clb-11. Cytochrome c subunits encoding genes qcrA and qcrC, as well as cytochrome c oxidase subunits encoding genes coxB and coxC were involved in the intracellular reduction of Cr (VI) by C. fimi Clb-11. Additionally, several unreported genes were found to be upregulated in C. fimi Clb-11 under Cr (VI) stress. Manganese transport protein encoding gene mntH and nickel transport system permease encoding genes ABC.PE.P and ABC.PE.P1 may participate in the passive uptake of Cr (VI) by C. fimi Clb-11. Osmoprotectant transport system ATP-binding protein encoding gene opuA, osmoprotectant transport system substrate-binding protein encoding gene opuC, and osmoprotectant transport system permease encoding gene opuBD may be crucial for maintaining intracellular water content in cells and enhancing the resistance of C. fimi Clb-11 to Cr (VI). Proton pump subunit encoding genes atpA, atpB, atpE, atpF, and atpH, as well as sodium-hydrogen antiporter subunit encoding genes mnhA and mnhC, may be involved in the extracellular proton secretion to reduce Cr (VI) in extracellular. Iron complex transport system substrate-binding protein encoding gene ABC.FEV.S, vacuolar iron transporter encoding gene VIT, FMN reductase gene encoding gene ssuE, and quinone oxidoreductase QOR encoding genes qor and qorB may participate in the intracellular reduction of Cr (VI) by C. fimi Clb-11. The pyruvate dehydrogenase encoding genes pdhA, pdhB, and pdhC, as well as the succinate dehydrogenase encoding genes sdhA, sdhB, and sdhD, may play important roles in supplying electrons for C. fimi Clb-11 to reduce Cr (VI). Our study provides theoretical references for optimizing microbial Cr (VI) resistance and microbial chromium pollution remediation techniques.
