“…55 Se element is a beneficial element for plant growth; according to Shi et el., Na 2 SeO 4 (1 mg/kg) alleviated the toxic effects of NP-Cd co-contamination on ryegrass plants by increasing the soil catalase activity and relative abundance of the beneficial microorganisms such as Micrococcales, Sphingomonas, Pseudarthrobacter, Gemmatimonadales, and Haliangium, which promoted the degradation of organic pollutants. 56 Li et al also showed that nano-Se application limited Cd absorption and transformation. It increased the pepper plant's defense by improving soil qualities (urease, fluorescein diacetate, brassinolide, indoleacetic acid, and syringic acid), allocating signaling molecule levels (rutin, luteolin, apigenin, brassinolide, and ABA), and boosting the abundance of beneficial microorganisms.…”

Nanoselenium (nano-Se) or melatonin (MT) foliar spray reduces pesticide stress by stimulating plant secondary metabolism and antioxidant capacity. However, the effects of nano-Se and MT biofortification on the interaction between plant secondary metabolic pathways and rhizosphere microbes in mitigating 2,4-D butyrate stress remain unknown. Compared to nano-Se or MT treatment alone, nano-Se and MT combined application increased the antioxidant enzyme activities and decreased the MDA (25.0%) and H 2 O 2 (39.3%) contents with 2,4-D butylate exposure. Importantly, they enhance the soil enzymes (S-FDA by 53.1%), allelochemicals (luteolin by 164.1% and tricin by 147.3%), as well as plant secondary metabolites (JA by 63.3% and 193.3% in leaves and roots) levels. It also improved the beneficial microbial abundance of Comamonadaceae, Sphingomonadaceae, and Rhodobacteraceae in the rhizosphere soil. In conclusion, nano-Se and MT alleviate 2,4-D butylate stress in wheat plants by enabling the interaction between rhizosphere microorganisms, allelopathic substances, and secondary metabolites.

In recent years, cadmium (Cd) contamination in agricultural soil has emerged as a significant global environmental issue, posing irreversible harm to crops and human health. As a result, efficient soil remediation techniques are urgently needed. For this issue, synergistic remediation by material and plant is an effective approach. In this study, a natural and green adsorption material (starch/montmorillonite composite, SMC) of Cd was prepared, which was further employed in synergistic remediation toward soil Cd contamination with the cadmium hyperaccumulator plant Bidens bipinnata. The results of the pot experiment demonstrated that an available Cd removal rate of 77.92 could be obtained, and the results of the field experiments demonstrate that the concentrations of Cd in contaminated soil could be reduced below the risk-screening values for agricultural land. Further analyses, including a microbial community diversity study, changes in soil BCR fraction components, and a TCLP toxicity leaching experiment, unequivocally elucidated that the synergy of SMC and Bidens bipinnata enhanced the remediation efficiency of Cd in contaminated soil. This study confirmed the application potential of the synergy of SMC and Bidens bipinnata toward Cd-contaminated soil.

“…Selenium is mostly found in plants as biomacromolecules like selenoproteins, selenonucleic acids, selenopolysaccharides, and compounds like selenocysteine, selenocysteine, and selenomethionine [4]. Selenium in soil is primarily categorized as selenate, selenite, selenide, elemental state selenium, organic state selenide, and volatile state selenium, with organic state selenide being the primary source of functional selenium in soil [5]. Plants receive selenium through their roots and foliage, and the primary types absorbed are Se 4+ and Se 6+ [6].…”

For investigating the effect of selenium on the growth of rice seedlings, this study used different concentrations of selenium ions (0, 0.5, 5, 10 and 20 µmol/L) to treat rice seedlings hydroponically. The experimental findings demonstrated that rice seedlings could grow and develop properly in the presence of a selenium deficiency (0 mol/L). Selenium ions had a positive impact on the development of rice seedlings at low and middle selenium concentrations of 0.5 mol/L and 5 mol/L, boosting plant height, above-ground fresh and dry weights. Selenium ions had a substantial inhibitory impact on the development of rice seedlings at high selenium concentrations of 10 mol/L and 20 mol/L.
