The morphology of upland cotton (Gossypium hirsutum L.) fruit branches critically determines the architecture and photosynthetic capacity of cotton plants, as well as the adaptability to planting patterns and mechanical harvesting. While key genes involved in nulliplex branching have been identified in cotton, the molecular mechanisms underlying the development of various fruit branch types in upland cotton remain largely uncharacterized.
Based on phenotypic identification and cytological measurement, this study integrated hormone profiling and transcriptomic analyses of four upland cotton varieties exhibiting varying lengths of the first internode of fruit branches. The results revealed that the loose internode phenotype arises from enhanced longitudinal growth of epidermal and xylem cells. In the short fruit branch internode group, jasmonic acid (JA) and salicylic acid (SA) accumulated significantly. Among the 954 differentially expressed genes (DEGs) between varieties with long and short internode lengths, 53 genes related to shoot apical meristem (SAM) development, the JA signaling pathway, and flowering regulation were predominantly upregulated in the short-internode group, imply a possible synergistic mechanism underlying the negative regulation of fruiting branch internode elongation. DEGs were predominantly enriched in hormone-related signaling pathways, with a strong emphasis on jasmonate signaling. Notably, members of the JAZ (TIFY family) gene showed a strong correlation with internode length and hormone content. Silencing a JAZ gene TIFY11B (GH_A05G1405) in short-internode cotton resulted in elongated internodes. The exploration offers novel insights into the molecular mechanisms underlying the internodes development of cotton fruiting branch from the perspective of hormone signal transduction.
陆地棉(Gossypium hirsutum L.)果实枝条的形态决定了棉花植株的结构和光合能力,以及对种植方式和机械收获的适应性。虽然在棉花中已经确定了参与无分枝的关键基因,但陆地棉花中各种果实分枝类型发育的分子机制仍未明确。本研究在表型鉴定和细胞学检测的基础上,对4个果实枝条第一节间长度不同的陆地棉花品种进行了激素谱分析和转录组学分析。结果表明,节间疏松表型是由于表皮和木质部细胞纵向生长增强所致。短果枝节间组茉莉酸(JA)和水杨酸(SA)积累显著。在954个长短节间差异表达基因中,53个与茎尖分生组织发育、JA信号通路和开花调控相关的基因在短节间组中显著上调,表明短节间组对果枝节间伸长的负调控可能存在协同机制。deg主要富集于激素相关的信号通路,特别强调茉莉酸信号通路。值得注意的是,JAZ (TIFY家族)基因的成员与节间长度和激素含量有很强的相关性。在短节间棉花中沉默JAZ基因TIFY11B (GH_A05G1405)导致节间延长。本研究从激素信号转导的角度对棉花结实枝节间发育的分子机制提供了新的认识。

Appropriate plant density could optimize light distribution within canopy and improve light use efficiency (LUE). However, most cotton studies have merely focused on whole canopy, and lacking in-depth exploration of the underlying mechanisms by which plant density regulates LUE as well as the gene expression. A two-year field experiment was conducted to assess the effect of plant density (low density, LD; moderate density, MD; high density, HD) on canopy light distribution, photosynthesis and its relevant gene expression, LUE, and cotton yield in upper, middle and lower canopy. The results showed that cotton responded to an increase in plant density by enhancing leaf area index at upper canopy, which subsequently led to higher fractional interception of photosynthetically active radiation (FIPAR) and a decrease of FIPAR at middle and lower canopy both in 2024 and 2025. Furthermore, HD caused a decline in photosynthetic rate (AN), chlorophyll content, leaf area, and specific leaf weight, which were significantly lower than those under MD. More importantly, LD and MD consistently achieved the maximum biomass and yield in 2024 and 2025, and biomass-based light use efficiency (LUEB) in each canopy under MD was higher than that under LD and HD. Meanwhile, random forest model showed that FIPAR played a dominant role in regulating the variation in LUEB, with AN coming second, and these variations were supported by regulating photosynthetic genes expression at different canopy layers under different densities. The partial least squares model indicated that yield is mainly influenced by LUEB and leaf photosynthesis. Overall, MD optimized canopy light distribution, fully exploited the photosynthetic productivity at middle and upper canopy, thereby enhancing LUE and yield potential.
适当的植物密度可以优化冠层内的光分布,提高光利用效率。然而,大多数棉花研究只关注整个冠层,缺乏对植物密度调控LUE的潜在机制和基因表达的深入探索。通过为期2年的田间试验,研究了不同种植密度(低密度,LD;中密度,MD;高密度,HD)对上、中、下冠层光照分布、光合作用及其相关基因表达、LUE和棉花产量的影响。结果表明:2024年和2025年,棉花通过提高冠层上部叶面积指数来响应植株密度的增加,从而导致光合有效辐射(FIPAR)截获分数增加,而冠层中部和下部的FIPAR下降;HD处理导致光合速率(AN)、叶绿素含量、叶面积和比叶重下降,且显著低于MD处理。更重要的是,LD和MD处理在2024年和2025年持续实现最大生物量和产量,且MD处理下各冠层生物量光利用效率(LUEB)高于LD和HD处理。同时,随机森林模型显示,FIPAR在调节LUEB变化中起主导作用,AN次之,这些变化与调节不同密度下不同冠层光合基因表达有关。偏最小二乘模型表明,产量主要受叶片光合作用和LUEB的影响。总体而言,MD优化了冠层光分配,充分利用了中上部冠层的光合生产力,从而提高了LUE和产量潜力。

Designing highly efficient, economically viable, and durable electrocatalysts for the hydrogen evolution reaction (HER) in alkaline electrolytes is critical for sustainable H2 generation. The electrocatalytic performance of catalyst typically depends on the number of surface-active sites. The amorphous/crystalline hetero-interface demonstrates distinctive properties, offering a novel approach to designing high-performance electrocatalysts with abundant active sites. In this work, nitrogen-doped carbon (NC) and ZIF-67-derived CNTs are strategically coupled to stabilize Ru-doped Co catalyst with amorphous/crystalline shell-core architecture. Ru doping optimizes the charge distribution of Co active sites, lowering the potential barrier for H2O dissociation and improving proton adsorption kinetics, thereby significantly improving the HER activity. Furthermore, the amorphous/crystalline structure creates active sites with high inherent activity, while the CNTs derived from ZIF-67 act as electron pathways and protective layers, significantly boosting OER performance. Specifically, the Ru-acCo@NC/CNTs needs a low overpotentials of only 32 mV to achieve a current density of 10 mA cm−2 in alkaline solution, which is obviously lower than that of cCo@NC/CNT (53 mV) and cCo@NC (244 mV). Besides, Ru-acCo@NC/CNTs catalyst exhibits great durability over 600 h working at 10 mA cm−2. Despite persistent challenges in high-current operation, this work establishes a feasible strategy to developing efficient HER electrocatalysts for sustainable energy technologies.
为碱性电解质中的析氢反应(HER)设计高效、经济可行、耐用的电催化剂是可持续制氢的关键。催化剂的电催化性能通常取决于表面活性位点的数量。非晶/晶异质界面具有独特的性能,为设计具有丰富活性位点的高性能电催化剂提供了新的途径。在这项工作中,氮掺杂碳(NC)和zif -67衍生的碳纳米管被策略性地耦合在一起,以稳定具有非晶/结晶壳核结构的ru掺杂Co催化剂。Ru掺杂优化了Co活性位点的电荷分布,降低了H2O解离的势垒,改善了质子吸附动力学,从而显著提高了HER活性。此外,非晶/晶体结构产生了具有高固有活性的活性位点,而源自ZIF-67的碳纳米管作为电子通路和保护层,显著提高了OER性能。具体来说,Ru-acCo@NC/CNTs仅需32 mV的过电位,即可在碱性溶液中达到10 mA cm−2的电流密度,明显低于cCo@NC/CNT(53 mV)和cCo@NC(244 mV)。此外,Ru-acCo@NC/CNTs催化剂在10 mA cm−2下工作时,耐久性超过600 h。尽管在大电流操作中存在持续的挑战,但这项工作为开发高效的可持续能源技术的HER电催化剂建立了可行的策略。

In the present research, zinc oxide (ZnO) nanoparticles (NPs) were biosynthesized through reduction by Anvillea garcinii leaf extract. A. garcinii leaves contain bioactive sesquiterpenes, terpenoids, and phenolic compounds, which are likely responsible for the reduction and stabilization of ZnO NPs. Compared to conventional physicochemical approaches, this synthesis method has several advantages, including simplicity, low cost, sustainability, and replicability. In this study, the impacts of various calcination (annealing) temperatures (60 °C and 500 °C) and different pHs (8, 10, and 12) on the properties of green-synthesized ZnO NPs were evaluated. Characterization was performed by analytical instruments including UV-Vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD) analyses, nanoparticle analyzer, and field emission scanning electron microscope (FE-SEM). The UV–Vis adsorption spectra of the ZnO NPs revealed a prominent peak at approximately 230 nm. The observed peaks in FTIR spectra align well with those reported in various studies on ZnO NPs. By microscopic observation and XRD validation, the spherical and hexagonal nature of ZnO NPs was confirmed. The pH and temperature used were effective on the particle size, so that the smallest NPs (16.4 nm) were obtained with the help of the most alkaline synthesis medium (pH 12) and oven drying (60 °C). While the largest dimension (63 nm) corresponded to the NPs synthesized under the lowest pH (8) and dried with a 500 °C furnace. Synthesized NPs exhibited high antioxidant properties. The small sizes of biosynthesized ZnO NPs and their phytochemical-coated surfaces affected their biological activity. The cytotoxic impact of NPs on the gastric cancer cells was dose-dependent, and IC50 values for ZnO prepared at 60 and 500 °C (coded as ZnO-60 and ZnO-500) were 35.11 and 42.7 μg/mL respectively. In addition, they were potent antimicrobial agents against Gram-negative bacteria Escherichia coli and 3 strains of Helicobacter pylori, and Gram-positive bacterium Staphylococcus aureus. The green synthesis of ZnO NPs represents a sustainable approach that minimizes environmental impact while producing effective nanomaterials. By using natural plant extracts, researchers can develop cost-effective and eco-friendly methods for NP production, enhancing their potential applications across diverse sectors such as medical fields, environmental science, and materials engineering.
本研究以黄花百合叶提取物为原料,通过还原法制备氧化锌纳米颗粒。garciinii叶片含有生物活性倍半萜、萜类和酚类化合物,这些化合物可能负责氧化锌NPs的还原和稳定。与传统的物理化学合成方法相比,该合成方法具有简单、低成本、可持续性和可复制性等优点。在本研究中,研究了不同的煅烧(退火)温度(60℃和500℃)和不同的ph值(8、10和12)对绿色合成ZnO NPs性能的影响。通过紫外可见光谱、傅里叶变换红外(FT-IR)光谱和x射线衍射(XRD)分析、纳米颗粒分析仪和场发射扫描电镜(FE-SEM)等分析仪器进行表征。ZnO纳米粒子的紫外-可见吸附光谱在约230 nm处有一个显著的峰。在FTIR光谱中观察到的峰与各种ZnO NPs研究中报道的峰一致。通过显微观察和XRD验证,证实了ZnO纳米粒子的球形和六方性质。pH和温度对颗粒大小有影响,在碱性最强的合成介质(pH 12)和烘箱干燥(60℃)下,得到最小的NPs(16.4 nm)。而最大尺寸(63 nm)对应于在最低pH(8)下合成并在500℃炉中干燥的NPs。合成的NPs具有较高的抗氧化性能。生物合成ZnO NPs的小尺寸及其植物化学包被表面影响了其生物活性。NPs对胃癌细胞的细胞毒作用呈剂量依赖性,60℃和500℃条件下制备的ZnO(编码为ZnO-60和ZnO-500)的IC50值分别为35.11和42.7 μg/mL。此外,它们对革兰氏阴性菌大肠杆菌和3株幽门螺杆菌以及革兰氏阳性菌金黄色葡萄球菌均有较强的抗菌作用。绿色合成ZnO纳米粒子代表了一种可持续的方法,可以在生产有效纳米材料的同时最大限度地减少对环境的影响。通过使用天然植物提取物,研究人员可以开发成本效益高且环保的NP生产方法,增强其在医疗领域,环境科学和材料工程等各个领域的潜在应用。

Roses, as one of the world's four major cut flowers, hold significant commercial value. Most existing research focuses on postharvest preservation to extend the shelf life, with little attention to balancing senescence, color, and fragrance. The effects of different temperatures (5 °C, 15 °C, and 30 °C) and durations (12 h and 24 h) treatments on the senescence, color, and fragrance of Rosa hybrida cultivar Tineke were investigated through metabolome, transcriptome, and double-stranded RNA (dsRNA)-mediated gene silencing strategy. After 12 h of exposure, the 30 °C treatment markedly improved the fragrance of cut roses, with no significant impacts on their shelf life or color, in contrast to the 5 °C and 15 °C treatments. Conversely, prolonged treatment at 30 °C for 24 h exerted adverse effects on both fragrance quality and shelf life. Additionally, short-term high-temperature treatment did not affect the petal color. Overall, short-term high-temperature treatment most effectively enhances cut rose quality. Treatment at 30 °C for 12 h induced the highest accumulation of the crucial floral fragrance compound 2-phenylethanol (2PE), which was mediated by alternative splicing (AS)-driven changes in the expression of full-length transcripts and AS transcripts. A high RhAAAT2 expression may be a critical factor in promoting increased 2PE accumulation in cut roses. This study revealed a novel mechanism of temperature-triggered AS regulating fragrance synthesis in cut flowers. It provides a promising physical strategy for balancing the preservation of cut flowers with improving their quality, showcasing significant potential for practical application.
玫瑰作为世界四大切花之一,具有重要的商业价值。现有的研究大多集中在采后保存以延长保质期,很少关注衰老,颜色和香味的平衡。通过代谢组学、转录组学和双链RNA (dsRNA)介导的基因沉默策略,研究了不同温度(5°C、15°C和30°C)和处理时间(12 h和24 h)对玫瑰(Rosa hybrida)品种Tineke衰老、颜色和香味的影响。暴露12 h后,与5°C和15°C处理相比,30°C处理显著改善了切花玫瑰的香味,对其保质期或颜色没有显著影响。相反,在30°C下长时间处理24 h对香味质量和保质期都有不利影响。此外,短期高温处理对花瓣颜色没有影响。总体而言,短期高温处理最有效地提高了月季切花品质。在30°C下处理12 h后,关键的花香化合物2-苯乙醇(2PE)的积累量最高,这是由选择性剪接(AS)驱动的全长转录本和AS转录本表达变化介导的。高表达的RhAAAT2可能是促进切花月季2PE积累增加的关键因素。本研究揭示了一种温度触发的AS调控切花香味合成的新机制。它为平衡切花的保存和提高切花的质量提供了一种有前途的物理策略,显示出巨大的实际应用潜力。

Most existing research focuses on postharvest preservation to extend the shelf life, with little attention to balancing senescence, color, and fragrance. The effects of different temperatures (5 °C, 15 °C, and 30 °C) and durations (12 h and 24 h) treatments on the senescence, color, and fragrance of <em>Rosa hybrida</em> cultivar Tineke were investigated through metabolome, transcriptome, and double-stranded RNA (dsRNA)-mediated gene silencing strategy. After 12 h of exposure, the 30 °C treatment markedly improved the fragrance of cut roses, with no significant impacts on their shelf life or color, in contrast to the 5 °C and 15 °C treatments. Conversely, prolonged treatment at 30 °C for 24 h exerted adverse effects on both fragrance quality and shelf life. Additionally, short-term high-temperature treatment did not affect the petal color. Overall, short-term high-temperature treatment most effectively enhances cut rose quality. Treatment at 30 °C for 12 h induced the highest accumulation of the crucial floral fragrance compound 2-phenylethanol (2PE), which was mediated by alternative splicing (AS)-driven changes in the expression of full-length transcripts and AS transcripts.

A glycoprotein (DSGP) from Salvia miltiorrhiza Bunge was purified by Tris-HCl extraction followed by DEAE-52 ion exchange chromatography. The approximate molecular weight (25.0 kDa) and monomeric nature were determined by reduced and non-reduced SDS-PAGE. The structure of DSGP was characterized by a practical and reliable “protein-polysaccharide analyzed by spectroscopy combined with chemical analysis” strategy. This study is the first to demonstrate that DSGP is an O-linked glucomannan protein, wherein its glycan moiety is a glucomannan chain with an average degree of polymerization (DP) of approximately 7. Hemagglutination assays confirmed that DSGP lacks lectin activity, indicating favorable safety properties. DSGP exhibits significant free radical scavenging activity and a unique advantage over ascorbic acid, namely that it does not produce hydrogen peroxide (H₂O₂) when exerting its antioxidant effects. In addition, as a hydrophilic colloid, DSGP can inhibit the sedimentation of pulp particles by enhancing electrostatic repulsion within the system, thereby exerting an excellent stabilizing effect on fruit juices. Therefore, these results suggested that glycoprotein DSGP could be used as a natural antioxidant and stabilizer in beverage industry.
采用Tris-HCl萃取,DEAE-52离子交换层析纯化丹参糖蛋白(DSGP)。通过还原和非还原SDS-PAGE测定了其近似分子量(25.0 kDa)和单体性质。采用实用可靠的“蛋白质-多糖光谱结合化学分析”策略对DSGP进行了结构表征。本研究首次证明了DSGP是一种o键型葡甘露聚糖蛋白,其中其聚糖部分是一个平均聚合度(DP)约为7的葡甘露聚糖链。血凝试验证实DSGP缺乏凝集素活性,表明其具有良好的安全性。DSGP具有显著的自由基清除活性和抗坏血酸的独特优势,即在发挥其抗氧化作用时不会产生过氧化氢(H₂O₂)。此外,DSGP作为一种亲水性胶体,可以通过增强体系内的静电斥力来抑制果肉颗粒的沉降,从而对果汁起到极佳的稳定作用。综上所述,糖蛋白DSGP可作为饮料工业的天然抗氧化剂和稳定剂。

The extensive use of synthetic plastic-based materials in packaging raises serious environmental and health concerns, driving the search for sustainable alternatives. Cellulose, as a renewable bio-based polymer, presents a promising solution; however, its hydrophilicity restricts its application in moisture-sensitive environments. The incorporation of bio-based coatings can enhance water resistance, yet scalable and efficient strategies remain a challenge in the food and beverage packaging sector. In this study, we present a fully bio-based coating system based on thermally polymerized Tung oil for producing functional cellulose-based materials with enhanced hydrophobicity. The influence of coating thickness, curing temperature, and curing time was investigated through ATR-FTIR, DSC, and TGA analyses, identifying 170 °C for 20 min as the optimal condition to achieve total crosslinking. After dispersion in dimethyl carbonate, Tung oil was applied to cellulose sheets and thermally cured, resulting in significantly improved water repellence while complying with European food contact regulations, as demonstrated by migration tests. Notably, the system was successfully integrated into commercial cellulose substrates, enabling the thermo-forming of 3D structures. Even at only 1 w/w % Tung oil loading, the water absorption of cellulose cups decreased by over 90 % compared to uncoated samples. Furthermore, recyclability tests confirmed that the thermo-formed cellulose objects treated with Tung oil remain completely recyclable into the paper stream. This study proposes a sustainable and potentially scalable strategy for the production of fully bio-based, recyclable, food compliant, and hydrophobic cellulose-based materials, offering a promising alternative to conventional plastic-based materials.
在包装中广泛使用合成塑料基材料引起了严重的环境和健康问题,促使人们寻找可持续的替代品。纤维素作为一种可再生的生物基聚合物,是一种很有前途的解决方案;然而,其亲水性限制了其在水分敏感环境中的应用。生物基涂料的结合可以增强耐水性,但可扩展和高效的策略仍然是食品和饮料包装领域的一个挑战。在这项研究中,我们提出了一种基于热聚合桐油的全生物基涂层体系,用于生产具有增强疏水性的功能性纤维素基材料。通过ATR-FTIR、DSC和TGA分析,考察了涂层厚度、固化温度和固化时间的影响,确定170°C、20 min是实现全交联的最佳条件。在碳酸二甲酯中分散后,将桐油涂在纤维素片上并进行热固化,结果显着提高了拒水性,同时符合欧洲食品接触法规,这是由迁移测试证明的。值得注意的是,该系统成功地集成到商用纤维素基质中,实现了3D结构的热成型。即使只有1 w/w %的桐油负荷,纤维素杯的吸水率也比未涂覆的样品下降了90% %以上。此外,可回收性测试证实,用桐油处理的热形成的纤维素物体仍然完全可回收到纸流中。这项研究提出了一种可持续的、潜在的可扩展策略,用于生产完全生物基的、可回收的、符合食品要求的、疏水的纤维素基材料,为传统的塑料基材料提供了一种有前途的替代品。

This study applied a natural deep eutectic solvent (NADES) consisting of malic acid and choline chloride for bioactive compound extraction from Reynoutria multiflora (Thunb.) Moldenke (syn. Polygonum multiflorum thunb), an important medicinal and agricultural resource. Optimization with 10 % water addition yielded a 90 % NADES system that significantly improved viscosity and mass transfer. The optimized extract provided higher or comparable yields of 2,3,5,4′-tetrahydroxystilbene-2-O-β-D-glucoside (THSG), emodin, and physcion compared with hot water or 70 % ethanol extracts. It also showed the highest enrichment of polymeric tannins and exhibited superior antioxidant capacity across multiple assays. GC/MS-based profiling and PLS-DA revealed a distinct volatile spectrum, while the extract demonstrated strong lipid peroxidation inhibition and COX-2 suppression, indicating its multifunctional bioactivity. Beyond laboratory performance, this approach emphasizes industrial relevance. The use of food compatible NADES offers a biodegradable, safe, and industrially viable alternative to conventional solvents for efficient extraction of bioactive compounds. The enhanced phytochemical recovery and multifunctional activities highlight the potential of P. multiflorum as a renewable crop resource for high-value applications in functional foods, nutraceuticals, pharmaceuticals, and natural preservatives. Furthermore, the strategy may be extended to other underutilized crops and agricultural by-products, promoting circular economy practices and adding value to medicinal plant resources.
