Soybean is a vital nutritional resource rich in protein, oil, vitamins, and minerals, serving as a leading global source of vegetable oil and helping combat undernourishment, especially in developing countries like Cameroon, where over 24 % of the population faces food insecurity. However, insufficient nutrients can severely hinder the formation of fruiting bodies, resulting in yields as low as one ton per hectare. This study explores the potential of enhancing nitrogen nutrition through Rhizobium bacteria to improve nodulation rates and overall soybean productivity. The objective was to assess the effects of various Rhizobium isolates on the productivity, physicochemical properties, and nutritional quality of soybeans, essential for agricultural development and food security. The experiment was carried out at IRAD Mbalmayo from March–July and September–November 2022. The experimental set-up was a completely randomized block design replicated thrice. Each replicate consisted of three elementary plots separated by 1 m. Crops were planted at 50 cm between rows and 10 cm between plants. Five treatments: control (S0), Rhizobium isolate No.1 (S1), Rhizobium isolate No.2 (S2), NoduMax (S3), NPK: 20-10-10 (S4), were applied to three varieties: V1 (TGX 1910–14F), V2 (MAKSOY 4N), V3 (TGX 1835 10E). Results showed that seed emergence rates varied from 69% to 99% among soybean varieties, with no significant differences across treatments. Notably, Rhizobium inoculation, particularly with isolate 2, significantly boosted growth, leading to greater plant height, leaf count, and flowering duration. The highest plant height recorded was 35.3 cm in the V2S2 treatment, while V1S2 had the highest number of leaves, reaching 43.73, at P = 0.05. Inoculated plants showed substantial yield improvements, achieving 2.9 tons per hectare, with increased pod and seed formation. Analysis of treated plants revealed variations in nitrogen, lipid, protein, carbohydrate, ash, and moisture content, underscoring the positive impact of inoculation. For example, lipid content ranged from 15.7% in V1S0 to 25.1% in V1S2, while the highest protein levels were recorded in V2S2 and V1S2. These results underscore the potential of Rhizobium inoculation as a sustainable strategy to enhance soybean production and contribute to food security.

大豆是一种重要的营养资源，富含蛋白质、油脂、维生素和矿物质，是全球植物油的主要来源，有助于解决营养不良问题，特别是在喀麦隆等发展中国家，那里24%以上的人口面临粮食不安全问题。然而，营养不足会严重阻碍子实体的形成，导致产量低至每公顷一吨。本研究探讨了利用根瘤菌提高氮素营养以提高结瘤率和大豆总产量的潜力。目的是评估各种根瘤菌分离株对大豆生产力、理化性质和营养品质的影响，这些对农业发展和粮食安全至关重要。该实验于2022年3月至7月和9月至11月在IRAD Mbalmayo进行。实验设置为完全随机分组设计，重复三次。每个重复由三个间距为1 m的基本样块组成。作物行间种植50厘米，株距种植10厘米。采用对照（S0）、根瘤菌1号（S1）、根瘤菌2号（S2）、NoduMax （S3）、NPK: 20-10-10 (S4) 5个处理，分别对3个品种V1 （TGX 1910-14F）、V2 （MAKSOY 4N）、V3 （TGX 1835 10E）进行处理。结果表明，大豆品种间种子出苗率为69% ~ 99%，处理间差异不显著。值得注意的是，接种根瘤菌，特别是分离物2，显著促进了生长，导致更高的株高，叶数和开花时间。V2S2处理最高株高为35.3 cm， V1S2处理叶片数最多，达到43.73，差异有统计学意义（P = 0.05）。接种植株的产量显著提高，达到每公顷2.9吨，荚果和种子形成增加。对处理植株的分析显示，在氮、脂、蛋白质、碳水化合物、灰分和水分含量方面发生了变化，强调了接种的积极影响。例如，V1S2的脂肪含量为15.7% ~ 25.1%，而V2S2和V1S2的蛋白质含量最高。这些结果强调了接种根瘤菌作为提高大豆产量和促进粮食安全的可持续战略的潜力。

Indian mustard is recognized as a resilient and economically important oilseed crop. However, its potential remains untapped due to the limited availability of short-duration, high-yielding varieties capable of outcompeting other rabi crops. Considering this notion, we have evaluated twenty-one F₂ and six BC₁F₁ populations derived from seven diversified parents of Brassica juncea following a Randomized Complete Block Design at Sher-e-Bangla Agricultural University. Based on key agronomic traits, the genetic components, heterosis, inbreeding depression, and gene action were studied to select early maturing and high-yielding populations. The percentage of heterosis was manifested in various cross-combinations, including P4 × P6 (91.45% for yield per plant) and P5 × P6 (28.52% for thousand seed weight), emerging as promising candidates for increasing productivity while managing negative inbreeding effects. Conversely, significant inbreeding depression was noted in traits like days to siliquae maturity and yield, particularly in crosses, P1 × P2 (6.29%) and P3 × P5 (21.74%), underscoring the need for careful selection in breeding programs to mitigate these effects. Variance analysis indicated that both additive and non-additive genetic interactions play a pivotal role in the inheritance patterns of the traits of interest. Among the six backcrosses, one promising line was (P5 × P6) × P5, demonstrating early maturity (107.00 DAS) with improved seed yield (12.47 g). This combination exhibited the potential for enhancing the adaptability and productivity by maintaining the maturity index and accelerating yield. Furthermore, significant phenotypic variation across yield-contributing traits was notable, whereas thousand seed weight and yield per plant showed high broad-sense and narrow-sense of heritability. Besides, positive correlations between seed yield and its attributing traits were noted, suggesting potential avenues for selection breeding. Collectively, the obtained findings enhance the understanding of genetic mechanisms underlying heterosis and inbreeding depression in B. juncea, providing insights and effective strategies for developing superior cultivars with optimized agronomic traits.

印度芥菜被认为是一种适应性强、经济上重要的油籽作物。然而，由于能够胜过其他rabi作物的短期高产品种有限，其潜力仍未得到开发。考虑到这一概念，我们在Sher-e-Bangla农业大学采用随机完全区组设计，评估了来自7个不同芥菜亲本的21个F2和6个BC1F1群体。根据主要农艺性状，对早熟高产群体的遗传组成、杂种优势、近交抑制和基因作用进行了研究。杂种优势比例表现在不同的杂交组合中，包括P4 × P6（单株产量91.45%）和P5 × P6（千粒重28.52%），是提高产量和管理负近交效应的有希望的候选组合。相反，在近交性状（如成熟期和产量）中，特别是在杂交组合P1 × P2（6.29%）和P3 × P5（21.74%）中，发现了显著的近交抑制，这强调了在育种计划中需要仔细选择以减轻这些影响。方差分析表明，加性和非加性遗传互作对感兴趣性状的遗传模式起关键作用。6个回交中，1个有希望的系为（P5 × P6） × P5，早熟（107.00 DAS），籽粒产量提高（12.47 g）。这种组合表现出通过保持成熟度指数和加速产量来提高适应性和生产力的潜力。单株千粒重和单株产量表现出较高的广义遗传力和狭义遗传力。籽粒产量与籽粒性状之间存在正相关关系，为选育提供了可能的途径。综上所述，这些发现有助于进一步了解芥菜杂种优势和近交抑制的遗传机制，为培育具有优化农艺性状的优良品种提供依据和有效策略。

The increased risk of chronic diseases has led to increasing importance of coarse foods in daily life, but the inclusion of new ingredients has a great degree of influence on the structural characteristics and sensory qualities of the food. The effects of five different particle size variations on the physicochemical characteristics, dough, and steamed bread structure of Flaxseed-based milk coproduct (FMC) were investigated. As the particle size decreases, the structure of the dough becomes denser due to an increase in water retention capacity and dissolution capacity, weakening the competition for dough moisture and allowing for an increase in air-holding capacity. The reduction in particle size increased the specific volume of the steamed bread, a decrease in the spread ratio, and an optimization of hardness and elasticity, as well as an increase in consumer acceptance of the FMC steamed bread. However, it is not the smaller the particle size, the higher the quality of steamed bread, appropriate reduction of particle size can improve the quality of steamed bread. In addition, the addition of FMC reduces fat digestion. Therefore, the present study proposes a method to change the particle size of FMC to optimize the quality of the steamed bread and to reduce fat digestibility by adding FMC.

慢性疾病风险的增加使得粗粮在日常生活中的重要性日益增加，但新成分的加入对食品的结构特征和感官品质有很大程度的影响。研究了5种不同粒度对亚麻籽奶副产品（FMC）理化特性、面团和馒头结构的影响。随着颗粒尺寸的减小，由于保水能力和溶解能力的增加，面团的结构变得更致密，削弱了对面团水分的竞争，并允许空气保持能力的增加。颗粒尺寸的减小增加了馒头的比容，降低了铺开比，优化了硬度和弹性，提高了消费者对FMC馒头的接受度。但并不是粒度越小馒头质量越高，适当降低粒度可以提高馒头质量。此外，FMC的添加减少了脂肪的消化。因此，本研究提出了一种通过改变FMC的粒径来优化馒头品质并通过添加FMC来降低脂肪消化率的方法。

Flax (Linum usitatissimum L.) is an important oil crop in the high-altitude arid regions of China. Flaxseed is rich in various nutrients. However, the nutritional qualities of flaxseeds from different producing areas are still unclear. In this study, the nutritional characteristics of flaxseed from five producing areas in China were investigated. Twenty five nutritional quality indices in flaxseed were analyzed. Subsequently, chemometric methods, including cluster analysis, principal component analysis (PCA) and partial least square discriminant analysis (PLS-DA), were employed to discover the characteristics of nutritional qualities in flaxseeds. The results revealed there are significant differences in nutritional qualities among flaxseeds from different production areas. Six quality indices including γ-tocopherol, vitamin E, phytosterols, oleic acid, α-linolenic acid, and cycloartenol were susceptible to producing area. In detail, the superiorcharacteristic nutrients of Ningxia flaxseed, Inner Mongolia flaxseed and Hebei flaxseed are vitamin E (17.3 mg/100g), α-linolenic acid (52.6%) and cycloartenol (1738.1 mg/kg), and phytosterols (3032.0 mg/kg), respectively. This study promotes the high-value development and utilization of local flaxseed industry.

亚麻（Linum usitatissimum L.）是中国高海拔干旱地区重要的油料作物。亚麻籽富含多种营养成分。然而，不同产地亚麻籽的营养品质仍不清楚。本研究对中国5个亚麻籽产地的亚麻籽营养特性进行了研究。对亚麻籽的25项营养品质指标进行了分析。随后，采用聚类分析、主成分分析（PCA）和偏最小二乘判别分析（PLS-DA）等化学计量学方法对亚麻籽营养品质特征进行了分析。结果表明，不同产地亚麻籽的营养品质存在显著差异。γ-生育酚、维生素E、植物甾醇、油酸、α-亚麻酸、环蒿烯醇6项品质指标对产地敏感。其中，宁夏亚麻籽、内蒙古亚麻籽和河北亚麻籽的优势特征营养成分分别为维生素E （17.3 mg/100g）、α-亚麻酸（52.6%）、环蒿烯醇（1738.1 mg/kg）和植物甾醇（3032.0 mg/kg）。本研究促进了当地亚麻籽产业的高价值开发利用。

Flooding can lead to oxygen deprivation in rapeseed, negatively affecting its growth and development and ultimately reducing yields. Vitreoscilla hemoglobin (VHb), a bacterial hemoglobin with a high oxygen-binding affinity, plays a key role in enhancing oxygen uptake and metabolic efficiency under low-oxygen conditions. Through genetic transformation, we overexpressed the VHb gene in rapeseed, which resulted in significant improvements in survival rate, root length, and biomass under submerged conditions. Additionally, we observed that transgenic plants developed adventitious roots in response to submergence stress. These transgenic plants also exhibited increased activities of ethanol dehydrogenase and pyruvate decarboxylase—enzymes associated with anaerobic respiration. Our findings indicate that VHb enhances flooding tolerance in rapeseed by promoting adventitious root formation and strengthening the plant's capacity for fermentation metabolism under anaerobic conditions.

洪水会导致油菜籽缺氧，对其生长发育产生负面影响，最终降低产量。玻璃体振荡菌血红蛋白（VHb）是一种具有高氧结合亲和力的细菌血红蛋白，在低氧条件下提高氧摄取和代谢效率起着关键作用。通过基因转化，我们在油菜籽中过表达了VHb基因，在淹水条件下显著提高了油菜籽的存活率、根长和生物量。此外，我们观察到转基因植物在淹水胁迫下产生了不定根。这些转基因植物还表现出乙醇脱氢酶和丙酮酸脱羧酶的活性增加，这些酶与厌氧呼吸有关。研究结果表明，VHb通过促进不定根的形成和增强植物在厌氧条件下的发酵代谢能力来增强油菜籽的耐涝能力。

Walnuts are rich in a variety of nutritional components. However, due to their high content of unsaturated fatty acids (UFAs), the quality of walnuts tends to decline during storage, which adversely affects the development of the walnut industry. This study was aimed to investigate the impacts of temperature and packaging methods on the storage quality and oxidative stability of walnuts. The Wen 185 walnut variety was selected, and the physical-chemical and nutritional indexes of walnuts stored for 42 weeks under different temperatures (−18 °C, 4 °C, and room temperature) and packaging methods (vacuum light-exposed, vacuum light-proof, vacuum-radiation light-exposed, vacuum-radiation light-proof, nitrogen-filled light-exposed, nitrogen-filled light-proof) were measured. The results showed that low temperatures, especially −18 °C, in combination with vacuum lightproof packaging, could effectively suppress the increase in oxidative stability indicators such as acid value (AV) and peroxide value (PV), and maintain high retention rates of nutritional indicators like tocopherol and phytosterol. This study has elucidated that low temperatures and appropriate packaging methods play the crucial roles in maintaining the quality and oxidative stability of walnuts during storage. It has provided comprehensive and valuable data support and theoretical basis for the scientific storage of walnuts, contributing to the development of the walnut industry and the guarantee of product quality.

核桃富含多种营养成分。然而，由于核桃中不饱和脂肪酸（UFAs）含量高，在贮藏过程中核桃的品质有下降的趋势，对核桃产业的发展造成不利影响。本研究旨在探讨温度和包装方式对核桃贮藏品质和氧化稳定性的影响。选取文185核桃品种，在不同温度（- 18℃、4℃、室温）和不同包装方式（真空光暴露、真空防光、真空辐射光暴露、真空辐射防光、充氮光暴露、充氮光暴露）下，测定核桃42周的理化指标和营养指标。结果表明，低温特别是- 18℃结合真空避光包装，可以有效抑制酸值（AV）和过氧化值（PV）等氧化稳定性指标的增加，并保持生育酚和植物甾醇等营养指标的高保存率。研究表明，低温和适当的包装方法对保持核桃贮藏期间的品质和氧化稳定性起着至关重要的作用。为核桃的科学贮藏提供了全面而有价值的数据支持和理论依据，为核桃产业的发展和产品质量的保证做出了贡献。

It has provided comprehensive and valuable data support and theoretical basis for the scientific storage of walnuts, contributing to the development of the walnut industry and the guarantee of product quality.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 3","pages":"Pages 212-222"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vitamin C, a potent antioxidant with broad therapeutic applications, is limited by rapid degradation under environmental stressors, which compromises its stability and bioactivity. This study addresses these limitations by formulating a double nano-emulsion (W/O/W) system incorporating macadamia oil and tea tree oil, using homogenization and phase inversion temperature (PIT) techniques. Comprehensive physicochemical characterization, including droplet size, polydispersity index (PDI), zeta potential, turbidity, Fourier transform infrared spectroscopy (FTIR), and SEM, was conducted alongside stability assessments under varying pH, temperature, and storage conditions. The optimized nano-emulsions exhibited nanoscale droplet sizes (10–40 nm), low PDI values (indicating high uniformity), and robust stability. Interestingly, the formulation with 2% W/O loading, with a particle size of 11.57 nm and a PDI of 0.04, demonstrated an antioxidant capacity of 4622.62 μg ascorbic acid equivalents (AA)/g, which was significantly higher (p < 0.05) compared to both natural oils (macadamia oil: 20.91 μg AA/g, tea tree oil: 16.86 μg AA/g) and a 10% Vitamin C aqueous solution (592.94 μg AA/g). FTIR analysis confirmed the molecular integrity of Vitamin C and its successful encapsulation with macadamia and tea tree oils, while SEM images revealed uniformly spherical and well-dispersed droplets. Moreover, the formulation retained its structural integrity and antioxidant functionality under diverse pH and thermal conditions. These findings underscore the potential of double nano-emulsion systems to overcome the stability challenges of Vitamin C, offering a promising approach to enhance its bioavailability and therapeutic performance in pharmaceutical and cosmetic applications.

维生素C是一种有效的抗氧化剂，具有广泛的治疗应用，在环境压力下迅速降解，这损害了它的稳定性和生物活性。本研究通过均质化和相转化温度（PIT）技术，将夏威夷果油和茶树油结合，形成双纳米乳液（W/O/W）体系，解决了这些限制。全面的物理化学表征，包括液滴大小、多分散性指数（PDI）、zeta电位、浊度、傅立叶变换红外光谱（FTIR）和扫描电镜，以及在不同pH、温度和储存条件下的稳定性评估。优化后的纳米乳液具有纳米级液滴尺寸（10-40 nm）、低PDI值（表明高均匀性）和稳定的稳定性。当W/O含量为2%，粒径为11.57 nm， PDI为0.04时，其抗氧化能力为4622.62 μg抗坏血酸当量(AA)/g，显著高于天然油（夏威夷果油：20.91 μg AA/g，茶树油：16.86 μg AA/g）和10%维生素C水溶液（592.94 μg AA/g）（p < 0.05）。FTIR分析证实了维生素C的分子完整性及其与夏威夷果和茶树油的成功包封，而SEM图像显示了均匀的球形和分散良好的液滴。此外，该配方在不同的pH和热条件下仍保持其结构完整性和抗氧化功能。这些发现强调了双纳米乳液系统克服维生素C稳定性挑战的潜力，为提高其在制药和化妆品应用中的生物利用度和治疗性能提供了一种有前途的方法。

Sesame is a multi-purpose high-value oilseed crop, which can beused in the food, feed, and cosmetics applications. The low yield of sesame is due to the lack of high-yielding and locally adapted varieties, which have the susceptibility to capsule shattering and biotic and abiotic stresses. The breeding gains in sesame are low and stagnant compared to other oilseed crops such as canola, groundnut and sunflower. Breeding for enhanced yield-related, oil quantity and quality, biotic and abiotic stresses tolerant varieties is vital to the adaptation of the climate change. Several genes and quantitative trait loci (QTLs) related to yield-related, oil quantity and quality, biotic and abiotic stresses tolerant have been identified through modern plant breeding tools in sesame. The depth understanding of the genetic basis, molecular mechanisms and regulatory genes involved in yield-related, oil quantity and quality, biotic and abiotic stresses tolerant in sesame is important for the improvement of sesame breeding programs. This article reviews and documents these achievements will provide fundamental data and references for practical applications of sesam research.

芝麻是一种多用途、高价值的油料作物，可用于食品、饲料、化妆品等领域。芝麻的低产量是由于缺乏高产和地方适应的品种，这些品种对蒴果破碎和生物和非生物胁迫敏感。与油菜籽、花生和向日葵等其他油料作物相比，芝麻的育种收益低且停滞不前。培育与产量相关、油的数量和质量、生物和非生物胁迫耐受性增强的品种对适应气候变化至关重要。利用现代植物育种工具，已经鉴定出与芝麻产量相关、油脂数量和品质、生物和非生物胁迫耐受性相关的几个基因和数量性状位点（qtl）。深入了解芝麻产量相关、油脂数量和品质、生物和非生物胁迫耐受性的遗传基础、分子机制和调控基因，对改进芝麻育种计划具有重要意义。本文对这些研究成果进行综述和整理，为芝麻的实际应用研究提供基础数据和参考。

This study focuses on the preparation, and optimization of the nanoemulsions coorporating with pumpkin seed oil, grape seed oil, and grapefruit essential oil using the phase inversion temperature (PIT) technique. The research investigated the impact of surfactant types and concentrations on critical nanoemulsion properties, including droplet size, polydispersity index (PDI), and zeta potential. Using a Box-Behnken Design (BBD) model, the formulation was optimized containing 6.0% plant oils, 10.0% Tween 80, 2.0% Span 80, and 1.0% lecithin to achieve nano-sized droplets (33.52 nm), with a low PDI (0.205), and a stable zeta potential (−15.49 mV). The antioxidant activity, was evaluated through 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays, demonstrating its outstanding efficacy. And the optimized nanoemulsion showed a radical-scavenging capacity exceeding 2250 μg ascorbic acid equivalents/g, significantly outperforming non-nanoemulsified oils. Stability testing under various environmental conditions highlighted exceptional robustness, with refrigerated samples maintaining structural integrity, minimal particle size growth, and consistent physicochemical properties over a 30-day storage period. The results suggest that the plant oil-based nanoemulsions exhibit strong antioxidant potential, offering a promising natural treatment for their application in cosmeceutical and therapeutic formulations.

The 2025 U.S.-China Trade War has intensified the vulnerability of China's oil supply chain due to heavy reliance on soybean imports, posing serious challenges to food security. This study examines soybean dependency risks and evaluates substitution strategies through diversified oilseed use, including palm-based alternatives. Findings show that high reciprocal tariffs caused a 75% drop in U.S. soybean exports to China. Palm oil, with high yield efficiency and cost-effectiveness, offers a viable supplement to fill supply chain gaps. Promoting oil palm cultivation through northward expansion and cooperation with Belt and Road countries is recommended. Additionally, multi-omics, gene editing, tissue culture, and precision agriculture are crucial to address technical bottlenecks. The study concludes that palm and soybean oils will form a complementary system, and that policy and technology investments are essential to strengthen China's oilseed supply chain resilience and sustainability.

由于严重依赖大豆进口，2025年中美贸易战加剧了中国石油供应链的脆弱性，对粮食安全构成严重挑战。本研究考察了大豆依赖风险，并通过多种油籽使用评估替代策略，包括以棕榈为基础的替代品。调查结果显示，高互惠关税导致美国对中国的大豆出口下降75%。棕榈油具有高产效率和成本效益，为填补供应链空白提供了可行的补充。建议通过向北扩张和与“一带一路”国家的合作，促进油棕种植。此外，多组学、基因编辑、组织培养和精准农业对解决技术瓶颈至关重要。该研究的结论是，棕榈油和大豆油将形成一个互补的系统，政策和技术投资对于加强中国油籽供应链的弹性和可持续性至关重要。
