Peanut is a major cash crop in the world. In recent years, peanut pod rot has become increasingly prevalent, resulting in significant yield and quality losses. Resistance breeding is considered a cost-effective approach for managing pod rot. Previous research in the United States identified significant anatomical differences in leaves and shells among peanut cultivars with varying responses to pod rot caused by Pythium myriotylum Drechs. and Rhizoctonia solani Kuhn. However, whether similar anatomical features correlate with resistance to peanut pod rot in Laixi, Qingdao, remained unknown, where the primary causal pathogen for the disease was F. solani. In this study, nine peanut varieties with differing disease reactions to peanut pod rot were planted in the same plots. Paraffin sections of leaves and shells were prepared and stained to evaluate anatomical features, and the main agronomic traits were assessed alongside leaf spot disease ratings. All the four anatomical features, leaf palisade cell number, palisade cell width, index (palisade cell number per mm × cell width in μm), and shell lignin staining area, were measured before the onset of pod rot and were found to be negatively correlated with pod rot scores. Given the consistent and strong correlation of these anatomical features with pod rot resistance and their high heritability estimates, the pre-existing resistance could be identified even in the absence of the disease, which is particularly valuable for fields where pod rot may not occur every year. This study provided useful anatomical indicators for selecting resistance to peanut pod rot, predominantly caused by F. solani.
花生是世界上主要的经济作物。近年来，花生豆荚腐病日益普遍，造成了严重的产量和品质损失。抗性育种被认为是控制豆腐病的一种经济有效的方法。美国先前的研究发现，不同花生品种对豆腐病的反应不同，其叶片和壳的解剖差异显著。和枯丝核菌。然而，类似的解剖特征是否与青岛莱西地区对花生荚果腐病的抗性相关仍不清楚，那里的主要致病病原体是梭兰氏菌。本试验在同一地块上种植9个对花生荚果腐病反应不同的花生品种。制备叶片和壳的石蜡切片并染色以评估解剖特征，并评估主要农艺性状和叶斑病等级。在荚果腐病发生前测定叶片栅栏细胞数、栅栏细胞宽度、栅栏细胞指数（栅栏细胞数/ mm ×细胞宽度（μm））和壳木质素染色面积这4个解剖特征，发现它们与荚果腐病评分呈负相关。考虑到这些解剖特征与荚果腐病抗性的一致性和强相关性以及它们的高遗传力估计，即使在没有疾病的情况下，也可以确定预先存在的抗性，这对于每年可能不会发生荚果腐病的田地特别有价值。本研究为选择花生荚果腐病抗性提供了有益的解剖学指标。

Avocados, including the peels and seeds, have beneficial nutritional value and can be processed into oils. To understand the trends and promote the use of avocado waste, it is essential to ascertain the scientific contributions, productivity, quality, and gaps in the avocado oil research field. This research identifies the changes in the research trend over the last ten years compared to previous studies. Additionally, this study examines and summarizes the research question, significant study findings, and future directions for avocado oil research through an overview format. Results show that the market for avocado oil has been growing, received greater attention, and been extensively studied in the last 10 years as opposed to the preceding century. There is more collaborative research on this topic globally from 2014 to 2023 than from 1928 to 2013. The direction of avocado oil research has not changed significantly; rather, it has expanded from the foundational studies and become more focused. Surprisingly, recent advancements indicate a notable increase in the research topic of avocado oil adulteration, implying that such practices have become more prevalent in the last decade compared to earlier periods. Though research hotspots noted that avocado oil is still being tested on animals, such as rats, the use of avocado oil for cosmetic purposes was not emphasized till 1928–2013. Other persisting hotspots include avocado being tried for antioxidant or oxidative stress prevention, insulin resistance prevention, extraction, compositional analysis, and avocado oils being compared alongside other oils.

The oilseed crop Camelina sativa exhibits salinity tolerance, but the effects on early growth stages across a range of different salts and in combination with salicylic acid (SA) have not been thoroughly evaluated. In this study, seeds were germinated in varying concentrations of six salts (NaCl, CaCl2, ZnCl2, KCl, MgSO4, and Na2SO4) with or without 0.5 mM SA. Using the halotime model, we estimated salt thresholds for germination and parameters of seedling growth. Germination and seedling growth parameters of camelina significantly decreased with increasing salt concentration across all salt types. Salts containing Zn and SO4 were most detrimental to germination and seedling growth. Except for KCl, 0.5 mM SA generally reduced the salinity tolerance threshold (Saltb(50)) of camelina. Specifically, Saltb(50) was 21.5% higher for KCl and 16.1%, 25.0%, 54.9%, 21.0%, and 5.6% lower for CaCl2, NaCl, MgSO4, Na2SO4, and ZnCl2, respectively, when 0.5 mM SA was compared to 0 mM SA. Furthermore, camelina seedling growth was consistently more sensitive than germination across all salt types. SA did not significantly enhance germination or seedling growth and was harmful when combined with certain salts or at the germination stage. It can be concluded that both the type of salt and the concentration of SA are as critical as the salt concentration in saline irrigation water.
油籽作物Camelina sativa表现出耐盐性，但一系列不同盐以及与水杨酸（SA）组合对早期生长阶段的影响尚未得到全面评估。在这项研究中，种子在不同浓度的六种盐（NaCl, CaCl2, ZnCl2, KCl， MgSO4和Na2SO4）中萌发，有或没有0.5 mM SA。利用halotime模型，我们估计了发芽的盐阈值和幼苗生长的参数。随着盐浓度的增加，亚麻荠种子萌发和幼苗生长参数均显著降低。含Zn和SO4的盐类对种子萌发和幼苗生长最不利。除KCl外，0.5 mM SA普遍降低了亚麻荠的耐盐阈值（Saltb(50)）。具体来说，当0.5 mM SA与0 mM SA相比，KCl的Saltb（50）提高了21.5%，CaCl2、NaCl、MgSO4、Na2SO4和ZnCl2的Saltb（50）分别降低了16.1%、25.0%、54.9%、21.0%和5.6%。此外，在所有盐类型中，亚麻荠幼苗生长始终比发芽更敏感。SA对种子萌发和幼苗生长的促进作用不显著，与某些盐类混用或在萌发期对幼苗生长有害。由此可见，盐的种类和SA的浓度与含盐灌溉水的盐浓度一样重要。

Bacterial wilt (BW) caused by Ralstonia solanacearum is a wide-spread and serious disease in peanut. To date, this soilborne disease could only be effectively controlled by planting resistant peanut cultivars. However, the relatively lower yield potential of the available BW-resistant peanut cultivars is a key reason restricting productivity in most epidemic regions naturally infested with the pathogen. Even small pods or seeds and low number per plant has been regarded as the key factor for the low yield potential both in BW-resistant peanut germplasm lines and available released cultivars, whether the resistance is closely linked with key yield components remains unclear. In this study, the relationship between pod weight and BW resistance was analyzed by using a recombinant inbred lines (RIL) population derived from a crossing combination between a high yielding cultivar Xuhua 13 and a BW-resistant cultivar Zhonghua 6. From the experiments, it was found that the BW resistance was not significantly correlated with pod number per plant (PNP), hundred pod weight (HPW) and pod weight per plant (PWP) in the RIL population. Based on linkage analysis, the quantitative trait locus (QTL)s related to PNP were identified on A06, A07, A08 and B03. The QTLs for HPW were detected on A05 and A07, and the QTLs for PWP were on A06, A07 and B03. However, the QTL for BW resistance identified on B02. These results indicated that the BW resistance and the pod number per plant as well as pod weight were inherited independently. Two recombined lines (QT0944 and QT1028) with high level BW resistance and large pods (hundred pod weight over 185g) were identified from the RILs, and they possessed the favored alleles of identified QTLs from both parents, which could be used in peanut breeding for high yield and high level disease resistance.

Global agriculture must urgently adopt a new approach to ensure adequate food production for the increasing population in the current context of adverse conditions, while prioritizing environmental sustainability. This change requires innovative and environmentally conscious methods, such as symbiotic-microorganisms-based products. Among these organisms, the genus Trichoderma stands out, as these fungal endophytes reside within many plant species including those in the Brassicaceae family and interact with them positively. Brassicaceae encompass numerous taxa of special agricultural and food interest, such as those known as oilseed brassicas (OSBs). Among these group are crops for obtaining canola and mustard seeds, commonly used for oil and spices production, respectively. OSBs are of greater interest for food because they are rich source of vitamins and minerals, and have also a great antimicrobial, antioxidant and antitumor potential application. Therefore, the improvement of these plant species (or of their cultivation methods) may ultimately lead to an improvement in human food and, accordingly, human health. This progress could go hand in hand with the Trichoderma fungal genus, either based on transgenesis with some of their genes, or using these fungi to formulate and produce bioinoculants. In relation to transgenesis, the most widely studied are those based on Trichoderma genes encoding endochitinases and Kelch-like family proteins, in both cases to achieve an antifungal effect against pathogenic fungi. With regard to Trichoderma-based products, these can be aimed at promoting plant growth, protecting crops against pathogens by acting as biological control agents (BCAs), or even reducing contaminants in the soil, such as heavy metals. The purpose of the present literature review is to analyse and discuss most of the existing studies to date on the interaction between OSB crops and Trichoderma fungi.

The cultivated peanut (Arachis hypogaea L.) is a significant edible oilseed crop. Although substantial progress has been made in breeding new peanut varieties through conventional methods, the narrow gene base of the cultivated peanut (stemming from six evolutionary bottlenecks) poses growing challenges for developing breakthrough varieties via intraspecific hybridization alone. Consequently, extensive efforts have been directed towards the utilization of incompatible wild Arachis species. In this study, we present the first genetic diversity assessment of 30 progenies derived from intersectional crosses between the high-oleic peanut cultivar Huayu 665 and two wild species, A. paraguariensis and A. appresipilla, alongside 32 cultivated materials and 29 wild accessions, using transposon element markers. The hybrids demonstrated greater genetic diversity than the cultivars, expanding the gene base for peanut breeding. Hybrid progenies with enhanced insect pest resistance and elevated levels of both oleic acid and oil/protein content were tentatively obtained. This work lays the groundwork for the future development of high-yielding, high-quality peanut varieties through the utilization of crop wild relatives.

Brassica clubroot caused by Plasmodiophora brassicae has been identified as a severe soil-borne disease that poses a significant threat to plants root systems. The disease results in the formation of tumorous enlargements in the roots, leading to wilting and eventual plant death. Consequently, crop yield is drastically reduced, causing substantial economic losses in agriculture. The current study aims to provide a comprehensive overview of recent research process on Brassica clubroot, focusing on the biological characteristics, physiological race identification, and pathogenic mechanism of P. brassicae. Furthermore, it covers the latest advancements in the comprehensive prevention and clubroot control. The insights gained from this study are expected to contribute to the future research on clubroot and the development of resistance breeding strategies.

Walnut oil (WO), known for abundant polyunsaturated fatty acids and an array of bioactive substances such as tocopherols, phytosterols, squalene, melatonin, and polyphenols, which is endowed with numerous health advantages. The primary objective of this research was to ascertain the impact of WO on cognitive deficits in learning and memory impairment mice caused by scopolamine (SCOP). The Morris water maze and the step-down avoidance test were utilized to assess the memory and learning capabilities. WO notably counteracted the detrimental effects of SCOP on learning and memory in the Morris water maze, as indicated by a reduction in escape latency and swimming distance. Likewise, WO administration led to a notably reduced number of errors in training trial and an increased latency in testing trial when compared to the SCOP group in the step-down avoidance test,. Moreover, WO activated the cholinergic system of the brain by upregulating choline acetyltransferase activity and reducing acetylcholinesterase activity.

核桃油（WO）以丰富的多不饱和脂肪酸和一系列生物活性物质（如生育酚、植物甾醇、角鲨烯、褪黑激素和多酚）而闻名，具有众多健康优势。本研究的主要目的是确定 WO 对东莨菪碱（SCOP）导致的学习和记忆障碍小鼠认知缺陷的影响。研究采用了莫里斯水迷宫和降阶回避测试来评估小鼠的记忆和学习能力。在莫里斯水迷宫中，WO明显抵消了SCOP对学习和记忆的不利影响，这表现在逃逸潜伏期和游泳距离的缩短上。同样，在降阶回避测试中，与 SCOP 组相比，施用 WO 可显著减少训练试验中的错误次数，增加测试试验中的潜伏期。此外，WO 还能通过上调胆碱乙酰转移酶活性和降低乙酰胆碱酯酶活性来激活大脑的胆碱能系统。这些结果表明，WO 具有防止小鼠记忆力衰退的潜力，为预防记忆相关疾病提供了一种很有前景的策略。

Structural variations (SVs), a newly discovered genetic variation, have gained increasing recognition for their importance, yet much about them remains unknown. With the completion of whole-genome sequencing projects in oil crops, more SVs have been identified, revealing their types, genomic distribution, and characteristics. These findings have demonstrated the crucial roles of SVs in regulating gene expression, driving trait innovation, facilitating domestication, making this an opportune time for a systematic review. We summarized the progress of SV-related studies in oil crops, focusing on the types of SVs and their mechanisms of occurrence, the strategies and methods for SV detection, and the SVs identified in oil crops such as rapeseed, soybean, peanut, and sesame. The various types of SVs, such as presence-absence variations (PAVs), copy number variations (CNVs), and homeologous exchanges (HEs), have been shown. Along with their genomic characterization, their roles in crop domestication and breeding, and regulatory impact on gene expression and agronomic traits have also been demonstrated. This review will provide an overview of the SV research process in oil crops, enabling researchers to quickly understand key information and apply this knowledge in future studies and crop breeding.

The Tangier-Tetouan-Al Hoceima (TTA) region is one of the main olive oil producing regions in Morocco. Little is devoted to characterize olive oil physicochemical traits from TTA hence the originality of this study. This aimed at investigating variation in olive oil quality produced from three Moroccan cultivars ‘Moroccan Picholine’, ‘Menara’, and ‘Haouzia’ and their blends. Sampling was performed in five provinces fromTTA (Northern Morocco) during four consecutive crop-seasons (2018–2021) considering three extraction technologies (ET): traditional discontinuous press system (SP) and continuous extraction systems including decanter of three outlets (3O) and decanter of two outlets (2O). Physicochemical measurements consisted of routinely quality parameters namely free acidity (FA), peroxide value (PV), UV absorption parameters (K232, K270, and ΔK), chlorophylls (Chl) and carotenoids (Car) contents, total phenolic compounds (TPC) and oxidative stability (OS). Crop season showed its superiority impacts on K232, OS, TPC, Chl, and OS. While cultivar was the main variability source in both PV and K270, and FA was mainly determined by ET. Important variations (p < 0.05) were reported among crop seasons and locations due to pedoclimatic differences. ‘Menara’ and ‘Haouzia’ had higher pigments content, TPC, and OS, and the blends displayed low pigments concentration, TPC, and OS. Expectedly, continuous ET (2O and 3O) had the greatest values of pigments content, TPC, and OS as revealed by principal component analysis. Strong correlations were highlighted among basic quality parameters, TPC, pigments, and OS. Simple linear regression was used to describe the relationships between OS and TPC (R2 = 0.856) and OS regressed against Chl (R2 = 0.690) and Car (R2 = 0.760), while TPC were regressed on Chl (R2 = 0.670) and Car (R2 = 0.680) and finally Chl against Car (R2 = 0.931). In conclusion, compared to technological, genotypic, and geographic effects, climatic conditions were the main factor driving olive oil stability and associated phenolics and pigments; oil cultivar blend seems to have negative effects on pigments concentration and total phenolic compounds as well as oxidative stability.
丹吉尔-特图安-胡塞马（TTA）地区是摩洛哥主要的橄榄油产区之一。对丹吉尔-特图安-胡塞马地区橄榄油理化特性的研究很少，因此本研究具有独创性。本研究旨在调查摩洛哥三个栽培品种 "Moroccan Picholine"、"Menara "和 "Haouzia "及其混合品种所产橄榄油质量的变化。在连续四个作物季（2018-2021 年）期间，在摩洛哥北部的五个省进行了采样，采用了三种萃取技术（ET）：传统的非连续压榨系统（SP）和连续萃取系统，包括三出口滗水器（3O）和两出口滗水器（2O）。理化测量包括常规质量参数，即游离酸度（FA）、过氧化值（PV）、紫外线吸收参数（K232、K270 和 ΔK）、叶绿素（Chl）和类胡萝卜素（Car）含量、总酚化合物（TPC）和氧化稳定性（OS）。作物季节对 K232、OS、TPC、Chl 和 OS 的影响较优。栽培品种是 PV 和 K270 的主要变异来源，而 FA 则主要由蒸散发决定。不同作物季节和地点之间存在着重要的差异（p < 0.05），这是由气候差异造成的。Menara'和'Haouzia'的色素含量、TPC和OS都较高，而混合作物的色素浓度、TPC和OS都较低。主成分分析表明，连续性蒸腾作用（2O 和 3O）的色素含量、TPC 和 OS 值最高。基本质量参数、TPC、色素和 OS 之间的相关性很强。简单线性回归用于描述 OS 与 TPC（R2 = 0.856）和 OS 与 Chl（R2 = 0.690）和 Car（R2 = 0.760）之间的关系，而 TPC 与 Chl（R2 = 0.670）和 Car（R2 = 0.680）以及 Chl 与 Car（R2 = 0.931）之间的关系。总之，与技术、基因型和地理效应相比，气候条件是影响橄榄油稳定性及相关酚类和色素的主要因素；混合油栽培品种似乎对色素浓度和总酚类化合物以及氧化稳定性有负面影响。
