An RF spacer creates a void between NaA and a mesoporous silica shell. • Shell thickness tunes curcumin loading in yolk–shell NaA@HMSNs. • NaA@HMSN-2 loads 124.0 mg/g curcumin and adsorbs Cd 2+ in vitro. • Curcumin release and Cd 2+ adsorption occur in the same buffer system. • HepG2 viability remains above 90% up to 64 μg/mL after 48 h. Cadmium contamination is an environmental and health concern. Here, a yolk–shell composite was constructed using sodium A-type zeolite (NaA) as the microporous yolk and a hollow mesoporous silica nanoparticle (HMSN) layer as the separated shell. Removal of a resorcinol–formaldehyde spacer generated an internal void, and three shell thicknesses were prepared. The NaA component provided Cd 2+ adsorption sites, whereas the amino-functionalized HMSN compartment was used for curcumin loading. N-NaA@HMSN-2, with an approximately 100 nm shell, loaded 124.0 mg/g curcumin. In buffer containing 100 mg/L Cd 2+ , Cur/N-NaA@HMSN-2 released 34.8% and 39.5% curcumin and adsorbed 73.8% and 67.8% Cd 2+ at pH 7.4 and 1.2, respectively. In HepG2 assays, all three NaA@HMSN carriers maintained more than 90% relative cell viability at concentrations up to 64 μg/mL after 48 h. These findings demonstrate coupled Cd 2+ adsorption and curcumin release under in vitro conditions and support further evaluation of this bifunctional material platform.

Summary Stone cells are often present in pear fruit, and they can seriously affect the fruit quality when present in large numbers. The plant growth regulator NAA, a synthetic auxin, is known to play an active role in fruit development regulation. However, the genetic mechanisms of NAA regulation of stone cell formation are still unclear. Here, we demonstrated that exogenous application of 200 μ M NAA reduced stone cell content and also significantly decreased the expression level of PbrNSC encoding a transcriptional regulator. PbrNSC was shown to bind to an auxin response factor, PbrARF13. Overexpression of PbrARF13 decreased stone cell content in pear fruit and secondary cell wall (SCW) thickness in transgenic Arabidopsis plants. In contrast, knocking down PbrARF13 expression using virus-induced gene silencing had the opposite effect. PbrARF13 was subsequently shown to inhibit PbrNSC expression by directly binding to its promoter, and further to reduce stone cell content. Furthermore, PbrNSC was identified as a positive regulator of PbrMYB132 through analyses of co-expression network of stone cell formation-related genes. PbrMYB132 activated the expression of gene encoding cellulose synthase ( PbrCESA4b/7a/8a) and lignin laccase ( PbrLAC5 ) binding to their promotors. As expected, overexpression or knockdown of PbrMYB132 increased or decreased stone cell content in pear fruit and SCW thickness in Arabidopsis transgenic plants. In conclusion, our study shows that the ‘PbrARF13-PbrNSC-PbrMYB132’ regulatory cascade mediates the biosynthesis of lignin and cellulose in stone cells of pear fruit in response to auxin signals and also provides new insights into plant SCW formation.

HighlightsWhat are the main findings?We optimized novel IBA–melatonin (MLT) and IBA–citric acid (CA) compound rooting formulas for hardwood cuttings of seven grape rootstocks, with 400 mg/L IBA + 1.2 mM MLT screened as the optimal universal formula.The optimal MLT combination significantly improved root morphology, root activity and soluble substance accumulation, and balanced endogenous hormone levels in grape rootstock cuttings.Transcriptome analysis revealed that MLT promotes adventitious rooting mainly by regulating plant hormone signal transduction and MAPK signaling pathways in grape rootstocks.What are the implications of the main findings?The optimized formulas provide practical technical support for large-scale and standardized propagation of grape rootstocks.The clarified physiological and molecular mechanisms advance the theoretical research on rooting regulation of woody plant cuttings.This work provides a new reference for the application of MLT and CA as efficient rooting promoters in horticultural cutting propagation.Efficient rooting is essential for the propagation of grape rootstocks. This study aimed to identify an effective rooting formulation for hardwood cuttings and to investigate its underlying physiological and molecular mechanisms. Seven grape rootstocks were treated with indole-3-butyric acid (IBA) combined with melatonin (MLT) or citric acid (CA), with IBA plus naphthaleneacetic acid (NAA) and water serving as controls. Rooting performance was comprehensively evaluated using morphological traits, physiological characteristics, endogenous hormone contents, and transcriptome analysis. Among all treatments, 400 mg/L IBA combined with 1.2 mM MLT exhibited the best rooting performance. This treatment significantly enhanced root activity, soluble sugar, and soluble protein contents. It also increased IAA and GA3levels and improved the IAA/ABA and GA3/ABA ratios compared with the controls. Transcriptome analysis of ‘110R’ revealed that MLT-responsive genes were mainly enriched in plant–pathogen interaction, hormone signal transduction, and MAPK signaling pathways. Transcription factor families including MYB, ERF, and NAC were identified as potential regulators. Collectively, these findings demonstrate that IBA–MLT combined application promotes rooting by regulating physiological metabolism, hormone balance, and gene expression, providing a theoretical basis for improving grape propagation efficiency.

Zeolite membranes have excellent application prospects in the separation of mixtures with molecular-level differences; however, the uneven distribution of active ingredients on the support causes defects in the zeolite membranes, limiting their industrial applications. In this study, compact NaX and NaA zeolite membranes with perfect pervaporation performance were prepared in reusable saturated membrane synthesis solutions. These saturated membrane synthesis solutions not only provided sufficient Si/Al components for the even growth of zeolite on the support, but also reduced the random deposition of zeolite particles on the support by reducing the formation of zeolite particles in the bulk solution, improving the quality of the resulting zeolite membranes. The separation factors of the obtained NaA and NaX zeolite membranes were greater than 10000 for the water/ethanol and methanol/MTBE mixtures, respectively. Moreover, the saturated synthesis solutions could be reused multiple times to synthesize zeolite membranes after nutrient supplementation, saving resources and reducing environmental pollution. This study presents reusable solutions for synthesizing compact zeolite membranes, promoting the development of membrane technology for environmental protection and energy conservation.

One of the main techniques for removing volatile organic compounds (VOCs) from the environment is catalytic combustion technology. Noble metal-loaded Zeolite catalysts have a promising future in the field of VOCs catalysis. In this study, NaA, NaX, NaY and ZSM-5 were produced by a simple hydrothermal method , and Pt particles were loaded onto the zeolite. Among the four zeolite-supported Pt catalysts with similar loading loads, Pt/NaA has the best catalytic oxidation performance of toluene, and the total conversion of toluene can be achieved at 160 °C. At the same time, it has good repeatability, and stability. A series of characterizations indicate the synthesis of pure phase NaA zeolites and the presence of a number of acid sites, active oxygen and Pt 0 species. The presence of these active substances promoted the adsorption and final oxidation of VOCs by the catalyst, which enabled Pt/NaA to exhibit the most excellent catalytic oxidation performance for toluene. In situ DRIFTS showed that surface reactive oxygen species in Pt/NaA acted as an important role in the catalytic oxidation of toluene. The preparation of high efficiency zeolite catalysts by simple synthesis method has broad future in the field of VOCs treatment.

Colloidal gas aphron (CGA) drilling fluid is an environmentally friendly near-balanced drilling technology that has been successfully applied to depleted oil/gas reservoirs. To overcome the limitations of its application in high-temperature drilling, acrylamide (AM), 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS), and N -vinylpyrrolidone (NVP) are grafted onto starch via inverse emulsion polymerization, and a foam stabilizer ESt-g-NAA with a temperature resistance of ≥150 °C is synthesized. The Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance ( 1 H-NMR) analysis suggest that all monomers are grafted onto starch efficiently. ESt-g-NAA has good solubility and thermal stability, as well as an excellent ability to stabilize foams at high temperatures. Based on microscopic observation, stable aphrons are generated successfully in the CGA drilling fluid prepared by ESt-g-NAA and surfactant after 150 °C aged. Results show that ESt-g-NAA based CGA drilling fluid aged at appointed temperatures (120–180 °C) is a high-performance drilling fluid with shear-thinning behavior, extremely high values of low shear rate viscosity (LSRV), and well-building capabilities.

A high-performance hybrid NaA/X zeolite was directly synthesized from natural volcanic rocks using a facile hydrothermal method. Response surface methodology with a central composite design was used to optimize the synthesis parameters (NaOH:ore ratio = 2.15, Si:Al ratio = 1.58, and crystallization temperature = 104 °C). Under optimal conditions, the synthesized material exhibited 93.46% relative crystallinity and a 42.65 mg g −1 ammonium‑nitrogen adsorption capacity. The hybrid NaA/X zeolite displayed distinct bimodal micropores (~0.4 nm from NaA zeolite and 0.8–1.4 nm from NaX zeolite). Integrating experimental characterizations and molecular simulations, we revealed a specific synergistic mechanism: The NaX zeolite dominated the ion exchange of NH 4 + ions, whereas the NaA zeolite played a selective role, preferentially capturing trace molecular NH 3 using its narrow micropores and high binding energy. This selective mechanism effectively mitigated the competitive occupancy of NH 3 within the NaX pores, liberating excess active sites for NH 4 + exchange and enhancing the adsorption efficiency. Regeneration tests demonstrated that the material retained a 91.2% regeneration efficiency after five consecutive cycles using a sodium chloride solution. This study provides a strategy for designing hybrid zeolites for ammonium‑nitrogen wastewater treatment.

Complexing agents (CAs) can be used for the removal of Cr(VI) via nanoscale Fe 0 (nZVI) reduction in cost-effective manner. However, nZVI is prone to aggregation and passivation, and some conventional CAs are toxic and difficult to biodegrade, potentially causing secondary pollution. Therefore, selecting an environmentally friendly CA for assisting in the removal of Cr(VI) via supported nZVI is imperative. Herein, NaA molecular sieve membrane-supported nZVI (nZVI/NaA-NF) was prepared via the secondary growth and liquid-phase reduction method using nickel foam (NF) as the carrier. The physicochemical characteristics of nZVI/NaA-NF before and after reaction were analysed via SEM, EDS, and XPS. A CA-improved nZVI/NaA-NF was used for the effective removal of Cr(VI) in a continuous fixed-bed system. Furthermore, the influences of various experimental factors including the CA type, CA concentration, solution pH, space velocity, and inlet Cr(VI) concentration on Cr(VI) removal were systematically investigated. The results demonstrated that nZVI particles were homogeneously immobilized on the NaA molecular sieve membrane/NF for fresh nZVI/NaA-NF, and tetrasodium iminidisuccinate (IDS-4Na) inhibited the aggregation of Cr(III)/Fe(III) (hydr)oxide precipitates during the reaction. IDS-4Na demonstrated excellent promotive effect on Cr(VI) removal via nZVI/NaA-NF. The breakthrough time for Cr(VI) in the addition of IDS-4Na was considerably longer than that of nZVI/NaA-NF alone. The breakthrough concentration of Cr(VI) only reached 1.1% and 9.9% of the inlet concentration at 220 and 240 min, with an IDS-4Na concentration of 4 mM, a pH of 2.5, and a space velocity of 0.265 min −1 . The Bohart–Adams model was appropriate to predict the initial part of Cr(VI) breakthrough curves in the nZVI/NaA-NF fixed bed. The saturated concentration ( N 0 ) increased with an increase in inlet Cr(VI) concentration. The Yoon–Nelson model afforded good fitting results for all breakthrough curves of Cr(VI). The k′ value increased with an increase in space velocity, and the τ value decreased.

Turpinia argutais an excellent medicinal plant mainly used for the treatment of pharyngitis, tonsillitis, and tonsillar abscesses. However, an efficient regeneration protocol using tissue cultures forT. argutadoes not exist. Its main medicinal constituents are flavonoids, particularly ligustroflavone and rhoifolin. Here, we aimed to establish a tissue culture system forT. argutafor the first time using annual stem segments with axillary buds harvested from the field of the Jiangxi Academy of Forestry as explants by dynamically determining the accumulation of effective functional components in the tissue culture plantlets. Orthogonal tests were conducted to compare the effects of different explant disinfection times, media, and exogenous hormone ratios on the induction of the axillary bud growth, successional proliferation, and rooting ofT. argutastem segments. The best explant disinfection effect was achieved by disinfecting theT. argutaexplant with 75% ethanol for 50 s, followed by 0.1% mercuric chloride (HgCl2) for 6 min, and the optimal media for successional proliferation and rooting were Murashige and Skoog (MS) + 0.2 mg/L of 6-benzyladenine (6-BA), + 0.03 mg/L of naphthaleneacetic acid (NAA), and ½ MS + 2.5 mg/L of indole-3-butyric acid + 0.5 mg/L of NAA, respectively. The detection of ligustroflavone and rhoifolin in tissue culture plantlets 0, 3, and 5 months after transplanting showed a significant increasing trend and eventually exceeded the content requirements of the 2020 Edition ofChinese Pharmacopoeia forT. arguta. Our findings provide, for the first time, an effective tissue culture system forT. arguta, thereby providing important information to support the germplasm preservation, innovation, and application ofT. argutain the future.

Auxins play crucial regulatory roles in plants coping with cadmium (Cd) stress. However, the regulatory mechanism by which auxins alleviate Cd toxicity in tomato seedlings remains unclear. Here, we demonstrate that exposure to Cd stress leads to dynamic changes in the auxin response in tomato roots, characterized by an initial increase followed by a subsequent weakening. Under Cd stress, tomato seedlings show primary root- and hypocotyl-growth inhibition, accompanied by the accumulation of Cd and reactive oxygen species (ROS) in the roots. The exogenous application of 1-naphthylacetic acid (NAA) does not mitigate the inhibitory effect of Cd toxicity on primary root growth, but it does significantly enhance lateral root development under Cd stress. Auxin transport inhibitors, such as 1-N-naphthylphthalamic acid (NPA) and 2,3,5-triiodobenoic acid (TIBA), aggravate the growth inhibition of primary roots caused by Cd stress. Additionally, lateral root development was inhibited by NPA. However, applying auxin synthesis inhibitors L-kynurenine (kyn) and yucasin alleviated the tomato root growth inhibition caused by Cd stress; between them, the effect of yucasin was more pronounced. Yucasin mitigates Cd toxicity in tomato seedlings by reducing Cd2+absorption and auxin accumulation, strengthening ROS scavenging, and reducing cell death in roots. These observations suggest that yucasin potentially mitigates Cd toxicity and improves the tolerance of tomato seedlings to Cd stress.

Lilium browniivar.viridulumis a popular natural health product that combines medicine and food. However, the lack of high-quality and efficient propagation technology has been a significant impediment to the development of theL. browniivar.viridulumindustry. In this study, bulb scales ofL. browniivar.viridulumwere used as materials to investigate the induction of bulblets from scales, as well as the proliferation and enlargement of the induced bulblets. An in vitro regeneration system forL. browniivar.viridulumwas successfully established. The most effective methods for scale disinfection were found to be 75% alcohol disinfection for 30 s and 10% Sodium Hypochlorite (NaClO) disinfection for 15 min. The recommended medium for scale differentiation was Murashige and Skoog (MS) + 0.05 mg·L−11-Naphthaleneacetic acid (NAA) + 0.25 mg·L−1Thidiazuron (TDZ) + 0.05 mg·L−1kinetin (KIN) + 30 g·L−1sucrose + 6 g·L−1Activated Charcoal (AC). The recommended medium for bulblet proliferation was MS + 1.5 mg·L−16-benzylaminopurine (6-BA) + 0.5 mg·L−1NAA + 30 g·L−1sucrose. The recommended medium for bulblet enlargement was Modified MS Medium (potassium dihydrogen phosphate (KH2PO4, KDP) doubled) + 90 g·L−1sucrose. Bulblets with diameters of 1.5 cm were transplanted, and the germination rate was 100%. This study established a systematic in vitro regeneration system forL. browniivar.viridulum, which will provide the foundation for industrial production ofL. browniivar.viridulumbulbs and improvement through genetic transformation.
