“…Through our transcriptomic analysis, we identified four differentially expressed isoflavone-7-O-methyltransferase genes between W and Y plants ( Table S2 ). O-methylation can improve the structural stability, protein affinity, and transport capacity of flavonoids [ 33 , 34 , 35 ]; thus, the decreased isoflavone-7-O-methyltransferase expression in W plants might reduce the stability and export of isoflavones. We also identified 13 ABC transporter genes ( Table S2 ), which are also involved in flavonoid transport [ 36 ].…”

Rhizobia form symbiotic relationships with legumes, fixing atmospheric nitrogen into a plant-accessible form within their root nodules. Nitrogen fixation is vital for sustainable soil improvements in agriculture. Peanut (Arachis hypogaea) is a leguminous crop whose nodulation mechanism requires further elucidation. In this study, comprehensive transcriptomic and metabolomic analyses were conducted to assess the differences between a non-nodulating peanut variety and a nodulating peanut variety. Total RNA was extracted from peanut roots, then first-strand and second-strand cDNA were synthesized and purified. After sequencing adaptors were added to the fragments, the cDNA libraries were sequenced. Our transcriptomic analysis identified 3362 differentially expressed genes (DEGs) between the two varieties. Gene ontology and Kyoto Encyclopedia of Genes and Genomes analyses revealed that the DEGs were mainly involved in metabolic pathways, hormone signal transduction, secondary metabolic biosynthesis, phenylpropanoid biosynthesis, or ABC transport. Further analyses indicated that the biosynthesis of flavonoids, such as isoflavones, flavonols, and flavonoids, was important for peanut nodulation. A lack of flavonoid transport into the rhizosphere (soil) could prevent rhizobial chemotaxis and the activation of their nodulation genes. The downregulation of AUXIN-RESPONSE FACTOR (ARF) genes and lower auxin content could reduce rhizobia’s invasion of peanut roots, ultimately reducing nodule formation. Auxin is the major hormone that influences the cell-cycle initiation and progression required for nodule initiation and accumulates during different stages of nodule development. These findings lay the foundation for subsequent research into the nitrogen-fixation efficiency of peanut nodules.

“…Generally, PECVD generates plasma by glow discharge under high‐frequency electrical field and high vacuum conditions to realize rapid growth of dense thin film at relatively low temperature [32], which has the advantages of strong film adhesion, excellent coating property, low deposition temperature and marginal influence on the structure and physical properties of the substrate. The energy of low‐temperature plasma is higher than that of these chemical bonds, so it is enough to break the molecular bonds on the polymer surface and cause a series of physical and chemical reactions such as etching, crosslinking, and grafting.…”

“…Graft polymerization has been recognized as one of the most effective methods for polymer surface modification, which can be achieved through chemical initiators, ultraviolet light, plasma, or ionizing radiation [ 31 , 32 ]. Due to the merits of efficiency, cleanliness, environmental friendliness, and the non-destructive nature of material internal structures, plasma has been widely applied in chemical and physical surface modifications [ 33 , 34 , 35 ]. However, the surface modification of polymers, for example, wettability, endowed with solely plasma treatment, will disappear since the active sites are not stable, which is known as the aging effect or hydrophobic recovery [ 36 ].…”

In this study, the plasma graft polymerization technique was used to graft glycidyl methacrylate (GMA) onto polypropylene (PP) melt-blown fibers, which were subsequently aminated with N-methyl-D-glucamine (NMDG) by a ring-opening reaction, resulting in the formation of a boron adsorbent denoted as PP-g-GMA-NMDG. The optimal conditions for GMA concentration, grafting time, grafting temperature, and the quantity of NMDG were determined using both single factor testing and orthogonal testing. These experiments determined the optimal process conditions to achieve a high boron adsorption capacity of PP-g-GMA-NMDG. Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersion spectrum analysis (EDS), and water contact angle measurements were performed to characterize the prepared adsorbent. Boron adsorption experiments were carried out to investigate the effects of pH, time, temperature, and boron concentration on the boron adsorption capacity of PP-g-GMA-NMDG. The adsorption isotherms and kinetics of PP-g-GMA-NMDG for boron were also studied. The results demonstrated that the adsorption process followed a pseudo-second-order kinetic model and a Langmuir isothermal model. At a pH of 6, the maximum saturation adsorption capacity of PP-g-GMA-NMDG for boron was 18.03 ± 1 mg/g. In addition, PP-g-GMA-NMDG also showed excellent selectivity for the adsorption of boron in the presence of other cations, such as Na+, Mg2+, and Ca2+, PP-g-GMA-NMDG, and exhibited excellent selectivity towards boron adsorption. These results indicated that the technique of preparing PP-g-GMA-NMDG is both viable and environmentally benign. The PP-g-GMA-NMDG that was made has better qualities than other similar adsorbents. It has a high adsorption capacity, great selectivity, reliable repeatability, and easy recovery. These advantages indicated that the adsorbents have significant potential for widespread application in the separation of boron in water.
