Rapeseed（Brassica napus L.）is highly sensitive to ammonium (NH4+)，and ABA is widely involved in plant stress responses, but its physiological regulatory role in rapeseed under ammonium stress remains unclear. Our study shows that ammonium stress boosts ABA synthesis in rapeseed, which enhances ammonium tolerance in a concentration-dependent manner. Under ammonium stress, inhibiting ABA synthesis downregulates carbon and nitrogen metabolism genes, exacerbating ammonium toxicity symptoms, while ABA addition reverses this effect. Structural equation modeling revealed that ABA primarily promotes ammonium assimilation by upregulating BnaGSs expression and enhancing its enzyme activity, while its effect on carbon metabolism likely serves a synergistic role by providing the carbon skeleton for ammonium assimilation. Further, the response of BnaGSs gene expression to ABA and the phenotype of gs1.1 s mutants confirmed the above results. Additionally, ABA can alleviate ammonium induced oxidative damage, ultimately significantly restoring leaf photosynthetic performance. Collectively, our results suggest that the synthesis of ABA in response to ammonium stress alleviates ammonium toxicity in rapeseed by enhancing NH4+ assimilation through synergistic carbon and nitrogen metabolism.
油菜（Brassica napus L.）对铵（NH4+）高度敏感，ABA广泛参与植物的胁迫响应，但其在铵胁迫下对油菜的生理调控作用尚不清楚。本研究表明，铵胁迫促进了油菜ABA的合成，并以浓度依赖性的方式增强了油菜的耐铵性。在铵胁迫下，抑制ABA合成可下调碳氮代谢基因，加重铵中毒症状，而添加ABA可逆转这一作用。结构方程模型表明，ABA主要通过上调bnags表达和增强其酶活性来促进铵态氮同化，而其对碳代谢的影响可能是协同作用，为铵态氮同化提供碳骨架。此外，BnaGSs基因表达对ABA的响应以及gs1.1 s突变体的表型证实了上述结果。此外，ABA能减轻铵态氮引起的氧化损伤，最终显著恢复叶片光合性能。综上所述，我们的研究结果表明，响应铵胁迫的ABA合成通过协同碳氮代谢促进NH4+同化，从而减轻了铵对油菜的毒性。

In response to the challenges of relatively low natural rubber (NR) quality in China and the lack of suitable tapping techniques for major rubber tree (Hevea brasiliensis) clones to enhance yield while maintaining quality, this study systematically evaluated the effects of three concentration gradients of ethephon (ET) stimulation (0.0 %, 1.0 %, and 1.5 %) on latex yield, physiological characteristics, tapping panel dryness (TPD) incidence, and raw NR quality of CATAS 73397 mid-aged rubber trees under a conventional low-frequency tapping system (S/2 d4). The results demonstrated that 1.0 % ET stimulation significantly increased dry rubber yield (DRY) by 88.26 % without compromising raw NR quality and elevating TPD risk. However, higher concentration stimulation elevated TPD risk and reduced rubber quality. This indicates that to balance yield, quality, and safety, appropriate ET stimulation is permitted to meet the actual needs of production. Under the S/2 d4 tapping system, a 1.0 % ET concentration proved more suitable for mid-aged CATAS 73397 rubber trees than 1.5 %, as it effectively boosted yield while ensuring safety and quality retention. Correlation analysis revealed that latex parameters such as nitrogen (N) content, total solids content (TSC), inorganic phosphorus (Pi) content, and sucrose (Suc) content exhibited significant (or highly significant) negative correlations with raw NR indicators including initial plasticity values (P0) and Mooney viscosity (VR), but highly significant positive correlations with plasticity retention index (PRI). These findings suggest that latex physiological characteristics are closely linked to raw NR quality, indicating their potential as predictive markers for quality assessment. This study establishes an optimized tapping protocol for CATAS 73397 to achieve both quality preservation and yield increase. Additionally, it provides a theoretical foundation for the scientific selection of stimulant concentrations and real-time monitoring of raw NR quality in production practices.
针对中国天然橡胶（NR）质量相对较低以及主要橡胶树（巴西橡胶树）无性系缺乏适宜的攻胶技术以提高产量和保持品质的挑战，本研究系统评价了3种浓度梯度（0.0 %、1.0 %和1.5 %）的乙烯利（ET）刺激对胶乳产量、生理特性、攻胶板干燥（TPD）发生率的影响。传统低频攻胶系统（S/2 d4）下CATAS 73397中龄橡胶树生胶质量的变化。结果表明，1.0 %的ET刺激在不影响天然橡胶质量和增加TPD风险的情况下，显著提高了干橡胶产量（dry） 88.26 %。然而，较高的浓度刺激会增加TPD风险，降低橡胶质量。这表明，为了平衡产量、质量和安全，允许适当的ET增产以满足实际生产需要。在S/2 d4采胶系统下，1.0 %的ET浓度比1.5 %的ET浓度更适合于中龄CATAS 73397橡胶树，能有效提高产量，同时保证安全性和品质保持性。相关分析表明，乳胶参数氮(N)含量、总固形物含量（TSC）、无机磷（Pi）含量、蔗糖（Suc）含量与原始NR初始塑性值（P0）、Mooney粘度（VR）呈显著（或极显著）负相关，与塑性保持指数（PRI）呈极显著正相关。这些研究结果表明，乳胶的生理特性与天然橡胶的质量密切相关，这表明它们有可能作为质量评估的预测指标。以CATAS 73397为原料，建立了保质增产的最佳攻丝方案。为生产实践中兴奋剂浓度的科学选择和原料NR质量的实时监测提供理论依据。

The development of high-performance waterborne polyurethane (WPU) from biomass materials represents a significant issue in green industry. In this work, a rosin-based epoxidized soybean oil polyol (RE) was synthesized via a ring-opening reaction between rosin acid and epoxidized soybean oil. RE was employed as a functional monomer in combination with castor oil to fabricate films (RECO-WPU), which exhibited excellent balance of mechanical strength, UV shielding and hydrophobicity. Characterization results confirmed the successful covalent incorporation of RE into the polyurethane network with its rigid aromatic structure well preserved, which led to significantly enhanced tensile strength and hydrophobicity. The tensile strength at break increased by 326.1 %, while the water contact Angle rose by 24.5 %. Moreover, RECO-WPU demonstrated remarkable UV-blocking performance, achieving near-complete blocking of UVB and UVC radiation and up to 63.2 % shielding efficiency in UVA region. Furthermore, a durable cotton fabric coating was prepared by impregnating cotton fabric with RECO-WPU emulsion. After five water washes, the water contact Angle of the fabric only decreased by 3.2 % and remained as high as 117.1°, and the UVA transmission rate was only 44.7 %. In addition, the coated fabric also demonstrated washing tolerance to HCl, NaCl and ethanol. This paper proposes a new strategy for developing high-performance, environmentally friendly and structurally stable WPU by utilizing renewable biomass resources.
利用生物质材料开发高性能水性聚氨酯（WPU）是绿色工业的一个重要课题。以松香酸和环氧大豆油为原料，通过开环反应合成了松香基环氧大豆油多元醇。以稀土为功能单体，与蓖麻油复合制备了具有良好机械强度、防紫外线性能和疏水性的RECO-WPU薄膜。表征结果证实了稀土成功共价结合到聚氨酯网络中，其刚性芳香结构得到了很好的保留，从而显著提高了拉伸强度和疏水性。断裂抗拉强度提高了326.1 %，水接触角提高了24.5 %。此外，RECO-WPU具有出色的紫外线阻挡性能，可以几乎完全阻挡UVB和UVC辐射，UVA区的屏蔽效率高达63.2 %。在此基础上，用RECO-WPU乳液浸渍棉织物，制备了耐久的棉织物涂层。经过5次水洗后，织物的水接触角仅降低3.2 %，保持在117.1°，UVA的透射率仅为44.7 %。此外，涂层织物还表现出对HCl， NaCl和乙醇的耐洗涤性。本文提出了利用可再生生物质资源开发高性能、环境友好型、结构稳定的WPU的新策略。

Chloride-induced corrosion is one of the most critical factors limiting the durability and service life of reinforced concrete (RC) structures, and improving chloride binding capacity is therefore of great significance for extending structural durability and reducing CO2 emissions in the cement industry. However, the practical application of chloride binding technology is still hindered by the lack of eco-friendly, low-cost, and highly dispersible nanomaterials. Herein, truly green, cost-effective, and highly dispersed leaf-derived carbon dots (CDs) are for the first time adopted to enhance chloride binding in cement pastes. Specifically, leaf-derived CDs are prepared via a one-step hydrothermal process using environmentally friendly and renewable litchi leaves as the precursor. The as-obtained CDs exhibit excellent dispersibility in simulated concrete pore solution. Notably, the incorporation of 0.2 wt% CDs increases the chloride binding capacity by 59.34 % after 28 days of immersion in 3 M NaCl solution. More importantly, the CDs-induced enhancement mechanism of chloride binding is elucidated based on a detailed investigation of phase compositions in various cement pastes. The results indicate that leaf-derived CDs accelerate cement hydration, leading to the formation of more C–S–H gel and Friedel’s salt, thereby significantly improving chloride binding. This work provides a truly green and cost-effective nanomaterial strategy to enhance the resistance of RC structures against chloride erosion, prolong their service life, and reduce CO2 emissions in the cement industry. Moreover, these findings pave the way for a promising waste-to-resource approach for biomass valorization.
氯化物腐蚀是限制钢筋混凝土结构耐久性和使用寿命的最关键因素之一，因此提高氯化物结合能力对延长结构耐久性和减少水泥工业二氧化碳排放具有重要意义。然而，由于缺乏环保、低成本、高分散性的纳米材料，氯离子结合技术的实际应用仍然受到阻碍。本文首次采用真正绿色、高性价比、高度分散的叶源碳点（CDs）来增强水泥浆中氯离子的结合。具体来说，叶子衍生的CDs是通过一步水热工艺制备的，使用环保和可再生的荔枝叶作为前体。所得CDs在模拟混凝土孔隙溶液中表现出优异的分散性。值得注意的是，0.2 wt%的CDs在3 M NaCl溶液中浸泡28天后，其氯离子结合能力提高了59.34 %。更重要的是，通过对各种水泥浆相组成的详细研究，阐明了cds诱导的氯离子结合增强机制。结果表明，叶片衍生的CDs加速了水泥水化，导致更多的C-S-H凝胶和Friedel 's盐的形成，从而显著改善了氯离子的结合。这项工作提供了一种真正绿色和具有成本效益的纳米材料策略，以增强钢筋混凝土结构对氯化物侵蚀的抵抗力，延长其使用寿命，并减少水泥工业中的二氧化碳排放。此外，这些发现为有前途的废物转化资源的生物质增值方法铺平了道路。

Industrial hemp has an excellent tolerance for lead (Pb) and accumulation capacity. Further improving the Pb tolerance in industrial hemp is of great interest for its future application in phytoremediation. Present study was performed to evaluate the various Pb contaminated soils (normal soil; Pb spiked soil using Pb(NO3)2 and Pb polluted mine soil) with the Pb level 1300 mg kg−1 and various treatments of the vermicompost (VC) and cerium oxide nanoparticles (CeO2 NPs), (T0 = no VC and CeO2-NPs; T1 = CeO₂ NPs (30 mg L−1); T2 = VC (5 % w/w of soil); and T3 = T1 + T2 on the Pb accumulation and hemp productivity. The findings indicated that Pb stress (artificially spiked and natural contamination) led to significant reduction in the growth, biomass, and physiological traits of hemp. The Pb polluted mine soil exhibits more harmful impacts in comparison to artificially Pb spiked soil. The sole application of CeO2-NPs leads to less pronounced enhancements in growth and development parameters at rapid growth and harvesting stage in comparison with soil applied VC treatment under the treated and untreated Pb-stressed plants. Combined application of CeO2-NPs and VC effectively reduced the malondialdehyde contents (41.34 %), increased the soluble protein (62.35 %) and soluble sugar (29.97 %) as compared to control group. Moreover, the co-active effect of VC and CeO2-NPs also had the prospects of reducing Pb accumulation in difference tissues by enhancing physiological resiliency in hemp. Particularly, combined use of VC and CeO2-NPs counteracted the adverse effect of Pb stress by boosting growth, biomass, enzymatic antioxidants, and osmoprotectants through limiting the Pb accumulation. Use of organic amendments (VC) and metallic oxide NPs (CeO2-NPs) holds promising tool for mitigating the Pb stress, offering a practical and viable approach for hemp production.
工业大麻对铅具有良好的耐受性和积累能力。进一步提高工业大麻的耐铅性对其在植物修复中的应用具有重要意义。本研究对铅水平为1300 mg kg−1的不同铅污染土壤（正常土壤、铅（NO3）2加铅土壤和铅污染矿山土壤）和不同处理的蚯蚓堆肥（VC）和氧化铈纳米颗粒（CeO2 NPs） (T0 = no VC和CeO2-NPs， T1 = CeO2 NPs（30 mg L−1）进行了评价；T2 = VC（5 % w/w土壤）；和T3 = T1 + T2对铅积累和大麻生产力的影响。结果表明，铅胁迫（人工加氮和自然污染）对大麻的生长、生物量和生理性状均有显著影响。与人工加铅土壤相比，铅污染对矿山土壤的有害影响更大。单独施用CeO2-NPs与VC处理相比，在处理和未处理的pb胁迫下，植物在快速生长和收获阶段的生长和发育参数的改善不明显。与对照组相比，CeO2-NPs和VC联合施用可有效降低丙二醛含量（41.34 %），提高可溶性蛋白含量（62.35 %）和可溶性糖含量（29.97 %）。此外，VC和CeO2-NPs的协同作用也有望通过增强大麻的生理弹性来减少不同组织中Pb的积累。特别是，VC和CeO2-NPs的联合使用通过限制Pb积累来促进生长、生物量、酶促抗氧化剂和渗透保护剂，抵消了Pb胁迫的不利影响。有机改性剂（VC）和金属氧化物NPs （CeO2-NPs）的应用有望缓解铅胁迫，为大麻生产提供了一条实用可行的途径。
