Rice (Oryza sativa L.) is considered as the most important staple food crop in the world, feeding half of the global population. One of the emerging concerns in rice is the fall armyworm (Spodoptera frugiperda, FAW), a highly polyphagous insect herbivore. Although FAW has been well studied across many host systems, rice-FAW interactions—including the effects of phenology and seed treatment—are less understood. In this study, we examined the response of FAW to rice under a thiamethoxam seed treatment across three different phenological stages (V5: tillering; V11: maximum tillering; R3: panicle exsertion). We used four commonly grown cultivars in USA, exposed them to FAW for a short period of 48 h, and conducted a separate long-term feeding experiment using an artificial diet fortified with leaf material from treated and untreated plants. Data on FAW growth and development traits, rice surface defense levels, and FAW larval feeding behavior were collected. Our results showed that FAW response was significantly affected by seed treatment and rice phenological stages. Interestingly, maximum tillering, the most resistant stage against FAW was also found to have the highest levels of epicuticular wax and trichomes (after the V5 stage)—the two major surface defenses compared to the reproductive stage. We also found that seed treatment negatively affected wax content and increased FAW mortality. In light of the consequent changes in pest biology and emerging insecticide resistance, our data highlight the importance of rice phenology and seed treatment effects on innate rice defenses, as well as their consequences for herbivore feeding.

水稻（Oryza sativa L.）被认为是世界上最重要的主要粮食作物，养活了全球一半的人口。水稻中出现的一个新问题是秋粘虫（Spodoptera frugiperda， FAW），一种高度多食的食草性昆虫。虽然FAW已经在许多寄主系统中得到了很好的研究，但水稻与FAW的相互作用——包括物候和种子处理的影响——还不太清楚。本研究通过三个物候阶段（V5：分蘖期；V11：最大分蘖期；R3：穗外伸期）研究了噻虫嗪种子处理下FAW对水稻的响应。本研究选用了4个美国常见品种，将其暴露于一汽中48 h，并分别进行了人工饲粮的长期饲养试验，饲料中添加了处理过和未处理过的植物叶片材料。收集了FAW生长发育性状、水稻表面防御水平和FAW幼虫取食行为等数据。结果表明，种子处理和水稻物候期对FAW的响应有显著影响。有趣的是，分蘖期最大，对FAW抗性最强的阶段也被发现具有最高水平的表皮蜡和毛状体（在V5期之后）-与生殖阶段相比，这两种主要的表面防御。我们还发现，种子处理对蜡含量和FAW死亡率有负面影响。鉴于害虫生物学的变化和新出现的杀虫剂抗性，我们的数据强调了水稻物候和种子处理对水稻先天防御的重要性，以及它们对食草动物摄食的影响。

Bagging is a generic technique to improve fruit quality in fruit trees, but its specific impact on the coloration of sweet cherries remains unclear. In this study, we integrated transcriptomic and metabolomic analyses to dissect the regulatory networks of metabolites and genes affected by yellow-black double-layered bagging. Our results demonstrated that bagging enhanced the coloration of ‘Lapins’ cherries, accompanied by significant increases in the concentrations of key anthocyanins (ACNs), including cyanidin-3-O-glucoside, pelargonidin-3-O-rutinoside, peonidin-3-O-rutinoside, and cyanidin-3-O-rutinoside. Bagged cherries also showed marked accumulation of glucose, D-sorbitol, and D-fructose, which may contribute to ACN synthesis. In terms of hormones, the concentrations of four compounds—one abscisic acid derivative, two auxins, and one jasmonic acid derivative—exhibited positive correlations with ACN accumulation, while two cytokinins exhibited negative correlations, suggesting hormone-specific regulatory roles in coloration. Transcriptomic analysis revealed that changes in ACN synthesis-related genes drove the observed coloration differences. Specifically, PavMYB10.1 and PavNAC02 acted as positive regulators, promoting ACN biosynthesis, while PavBBX24 functioned as a negative regulator, preventing excessive ACN accumulation under normal light conditions. These findings suggest that bagging affects sweet cherry fruit coloration by regulating ACN accumulation, thereby enhancing our understanding of the underlying molecular mechanisms.

套袋是一种提高果树果实质量的通用技术，但其对甜樱桃颜色的具体影响尚不清楚。在这项研究中，我们整合了转录组学和代谢组学分析，剖析了受黄黑双层套袋影响的代谢物和基因的调控网络。我们的研究结果表明，套袋增强了“Lapins”樱桃的颜色，同时显著增加了关键花青素（acn）的浓度，包括花青素-3- o -葡萄糖苷、天竺葵苷-3- o -芦丁苷、芍药苷-3- o -芦丁苷和花青素-3- o -芦丁苷。袋装樱桃也显示出葡萄糖、d -山梨醇和d -果糖的显著积累，这可能有助于ACN的合成。在激素方面，四种化合物（一种脱落酸衍生物、两种生长素和一种茉莉酸衍生物）的浓度与ACN积累呈正相关，而两种细胞分裂素的浓度呈负相关，表明激素特异性调节着颜色。转录组学分析表明，ACN合成相关基因的变化驱动了观察到的颜色差异。具体来说，PavMYB10.1和PavNAC02作为正调节因子，促进ACN的生物合成，而PavBBX24作为负调节因子，在正常光照条件下防止ACN的过度积累。这些发现表明，套袋通过调节ACN积累来影响甜樱桃果实的颜色，从而增强了我们对潜在分子机制的理解。

Pectin is a key component of plant cell walls that impacts plant development by modulating cell adhesion and wall stiffness through methylesterification by pectin methylesterase (PME). While its role in primary cell walls is well established, its specific functions and regulatory mechanisms in secondary xylem (i.e., wood formation) remain poorly understood. This study investigated the role of pectin methylesterification in wood development. We discovered that both low- and high-methylesterified homogalacturonan (HG) are abundant in the cambium and expanding xylem regions of secondary vascular tissues. Using integrative bioinformatics approaches, we identified 75 PtrPMEs and 61 PtrPMEIs within the Populus trichocarpa genome, many of which are highly expressed during wood formation. Notably, several PtrPMEs and PtrPMEIs with similar expression patterns are capable of interacting, suggesting post-translational regulation of PME activity during wood formation. Specifically, the highly expressed PtrPME10, PtrPME70, PtrPMEI50, and PtrPMEI58 during secondary cell wall deposition were co-expressed with genes involved in monolignol polymerization across 51 poplar tissues and organs, implying a putative role in lignin biosynthesis. Furthermore, overexpression of the Populus ortholog of PtrPME45 in P. davidiana × bolleana led to increased demethylesterification of HG, resulting in reduced lengths and widths of vessel and fiber cells in secondary xylem. Our study uncovers specific roles of PME in wood formation and elucidates regulatory mechanisms controlling PME activity during wood development. These findings on the interplay between PME and lignin biosynthesis provide a potential strategy for genetic improvement of woody plants, with implications for forestry and bioenergy applications.

果胶是植物细胞壁的重要组成部分，通过果胶甲基化酶（PME）的甲基化反应调节细胞粘附和细胞壁硬度，从而影响植物的发育。虽然它在初生细胞壁中的作用已经确定，但它在次生木质部（即木材形成）中的具体功能和调节机制仍然知之甚少。研究了果胶甲基化反应在木材发育中的作用。我们发现，在次生维管组织的形成层和扩张木质部中，低甲基化和高甲基化的均半乳糖酸（HG）含量丰富。利用综合生物信息学方法，我们在毛杨基因组中鉴定了75个PtrPMEs和61个PtrPMEIs，其中许多在木材形成过程中高度表达。值得注意的是，几种具有相似表达模式的PtrPMEs和PtrPMEIs能够相互作用，这表明PME活性在木材形成过程中受到翻译后调控。具体来说，在次生细胞壁沉积过程中高表达的PtrPME10、PtrPME70、PtrPMEI50和PtrPMEI58与51个杨树组织和器官中参与单脂醇聚合的基因共表达，这意味着可能在木质素生物合成中起作用。此外，在杨树同源基因PtrPME45的过表达导致了HG的去甲基化反应增加，导致次生木质部导管细胞和纤维细胞的长度和宽度减小。我们的研究揭示了PME在木材形成中的具体作用，并阐明了木材发育过程中控制PME活性的调节机制。这些关于PME与木质素生物合成之间相互作用的发现为木本植物的遗传改良提供了潜在的策略，对林业和生物能源的应用具有重要意义。

With rapid advancements in sequencing technologies, the genomes of numerous plant species have been deciphered. Among these, apple—a globally important fruit crop—has greatly benefited from such progress, with numerous high-quality genome assemblies providing valuable resources for genomic research and gene family studies. In this study, we analyzed the genomic characteristics of 26 Malus accessions, identified and classified their transcription factor (TF) families, and conducted a comprehensive pangenome-wide investigation of the TCP gene family across these accessions. Our findings revealed a strong positive correlation between genome size and transposable element (TE) content, suggesting TEs play a role in genome expansion. TF profiling showed significant variation in the abundance of certain families among different accessions. Specifically, 932 TCP genes were grouped into three subfamilies (PCF, CIN, and CYC/TB1) with a consistent compositional pattern. Orthologous gene group (OGG) analysis among the 26 Malus accessions revealed that core TCP genes were relatively conserved in gene count and possessed longer gene sequences and coding sequences (CDS). Synteny analyses indicated strong evolutionary conservation, with purifying selection acting on most TCP genes. Functional enrichment analysis highlighted the functional diversity within the TCP gene family. Moreover, transcriptomic analyses during adventitious shoot (AS) regeneration showed that core TCP genes were expressed at higher levels than non-core ones and identified some candidate TCP genes potentially involved in regulating AS formation. This study provides valuable insights into the evolutionary conservation and functional diversity of the TCP gene family, revealing its potential regulatory roles in AS regeneration in apple.

随着测序技术的快速发展，许多植物物种的基因组已经被破译。其中，苹果作为一种全球重要的水果作物，其大量高质量的基因组组装为基因组研究和基因家族研究提供了宝贵的资源。本研究分析了26份苹果材料的基因组特征，对其转录因子（TF）家族进行了鉴定和分类，并对这些材料的TCP基因家族进行了全基因组范围的研究。我们的研究结果表明，基因组大小与转座因子（TE）含量呈正相关，表明TE在基因组扩增中起作用。TF谱分析显示，不同种质间某些家族的丰度存在显著差异。具体而言，932个TCP基因被分为三个亚家族（PCF， CIN和CYC/TB1），其组成模式一致。同源基因群（OGG）分析表明，核心TCP基因在基因数量上相对保守，且具有较长的基因序列和编码序列（CDS）。Synteny分析显示了强烈的进化保守性，纯化选择作用于大多数TCP基因。功能富集分析强调了TCP基因家族的功能多样性。此外，转录组学分析表明，核心TCP基因的表达水平高于非核心基因，并确定了一些可能参与调控AS形成的候选TCP基因。该研究为TCP基因家族的进化保护和功能多样性提供了有价值的见解，揭示了其在苹果AS再生中的潜在调控作用。

Climate change has been linked to a wide range of adverse impacts on human health and socioeconomic well-being. While mushrooms have been suggested as potential agents for mitigating climate change, the effects of climate change on mushroom production remain largely unexplored. Here, we review and analyze the potential impacts of climate change on the production of both cultivated and wild edible and medicinal mushrooms, with a focus on the impacts of changing temperature and precipitation. First, we review global temperature and precipitation scenarios projected by 2100. Most climate scientists predict that global temperature will continue to rise gradually and precipitation distribution will become increasingly uneven in the future. Second, our analyses suggest that these environmental shifts will negatively impact the productivity of most cultivated mushrooms in multiple ways, including restricted substrate supplies, damage from pests and pathogens, and high electrical expenditures, etc. Third, some wild mushrooms may benefit from warmer and more humid conditions in certain regions, leading to increased mycelial growth and fruiting. However, hotter and drier environments in other regions, as projected for the future, will likely suffer decreasing yields for most mushrooms. For many wild gourmet mushroom species, their suitable habitats may change, with the majority predicted to experience habitat shrinkage, resulting in an overall decrease in productivity. Aside from challenges, we also discuss opportunities, including incorporating smart technologies for monitoring environmental factors, utilizing artificial intelligence for predictive analytics, and automating tasks such as irrigation and cooling/heating. We note that long-term monitoring across multiple ecological zones is needed to accurately quantify the impacts of global climate change on mushroom production and fine-tune strategies for sustainable mushroom cultivation.

气候变化与对人类健康和社会经济福祉的广泛不利影响有关。虽然蘑菇被认为是缓解气候变化的潜在媒介，但气候变化对蘑菇生产的影响在很大程度上仍未被探索。在此，我们回顾和分析了气候变化对栽培和野生食用菌生产的潜在影响，重点关注了温度和降水变化的影响。首先，我们回顾了2100年全球温度和降水预测情景。大多数气候科学家预测，未来全球气温将继续逐渐上升，降水分布将变得越来越不均匀。其次，我们的分析表明，这些环境变化将以多种方式对大多数栽培蘑菇的生产力产生负面影响，包括限制基质供应，害虫和病原体的破坏以及高电力支出等。第三，一些野生蘑菇可能受益于某些地区更温暖、更潮湿的环境，导致菌丝生长和结果增加。然而，正如未来预测的那样，其他地区更热、更干燥的环境可能会导致大多数蘑菇的产量下降。对于许多野生美食蘑菇物种来说，它们的适宜栖息地可能会发生变化，其中大多数预计会经历栖息地萎缩，导致生产力整体下降。除了挑战，我们还讨论了机遇，包括整合智能技术来监测环境因素，利用人工智能进行预测分析，以及自动化任务，如灌溉和冷却/加热。我们注意到，需要跨多个生态区进行长期监测，以准确量化全球气候变化对蘑菇生产的影响，并微调可持续蘑菇种植策略。

Seneca Valley virus (SVV), an emerging picornavirus, poses a significant threat to the global swine industry. Innate immunity acts as the initial defense mechanism of host cells against viral infection. Upon infection, viruses can be detected by the cellular host's pattern recognition receptors (PRRs), which trigger the activation of signaling cascades and the strong production of type I interferon (IFN-I) to limit viral replication. SVV employs diverse strategies to evade innate immunity, primarily through 3C protease, which targets host antiviral proteins to antagonize IFN-I signaling. Additionally, SVV hijacks autophagy, apoptosis, and pyroptosis to facilitate its own replication. In this review, we summarize recent research on the underlying mechanisms employed by SVV to manipulate host innate immune response and programmed cell death pathways. This review will provide insights for the design of SVV vaccines and contribute to the prevention and control of SVV infection.

塞内卡谷病毒（SVV）是一种新兴的小核糖核酸病毒，对全球养猪业构成重大威胁。先天免疫是宿主细胞抵御病毒感染的初始防御机制。感染后，病毒可被细胞宿主的模式识别受体（PRRs）检测到，从而触发信号级联反应的激活和I型干扰素（IFN-I）的强烈产生，以限制病毒的复制。SVV采用多种策略逃避先天免疫，主要通过3C蛋白酶，其靶向宿主抗病毒蛋白拮抗IFN-I信号。此外，SVV劫持自噬、凋亡和焦亡以促进自身复制。在这篇综述中，我们总结了SVV操纵宿主先天免疫反应和程序性细胞死亡途径的潜在机制的最新研究。这一综述将为SVV疫苗的设计提供新的思路，并有助于SVV感染的预防和控制。

Livestock body conformation is a key indicator for evaluating an animal's production performance, health status, and breeding value. Traditional conformation assessment methods, which rely on manual measurements and visual scoring, are not only time-consuming and labor-intensive but also prone to subjective. With the rapid development of computer vision and artificial intelligence technologies, novel approaches leveraging two-dimensional (2D) images, three-dimensional (3D) point cloud processing, and multimodal data fusion have become research hotspots in the field of automated conformation assessment. This paper reviews the progress of computer vision applications in livestock body conformation assessment, highlighting key methods and their potential practical value. The review encompasses core technologies such as expert knowledge-based approaches, data collection and preprocessing techniques, classical machine learning algorithms, and advanced deep learning models. Specifically, it elaborates on the implementation methods, application scenarios, and typical outcomes of these techniques in body size measurement, limb and hoof detection, reproductive organ detection, and udder detection. Furthermore, the main challenges in applying computer vision to livestock conformation assessment are outlined, including data quality issues, algorithm generalization capability, real-time performance limitations, and the cost and complexity of device deployment. Future research should aim to improve data quality, model adaptability, and deployment efficiency, ensuring scalable and cost-effective conformation assessment solutions.

Functional plants play a pivotal role in plant protection by bolstering the populations of pests’ natural enemies. When utilized as companion plants, they serve as crucial components in conservation biological control. A systematic analysis of the ecological functions of candidate companion plant species is of utmost importance for effectively attracting and sustaining natural enemies, thereby promoting biological control strategies. In this study, we comprehensively examined the impact of Cosmos bipinnata (Asteraceae) on the olfactory behavior, lifespan, and survival of Harmonia axyridis, and evaluated its function in maintaining field populations and pest control capabilities. Compared to the absence of companion plants, C. bipinnata leaves at the vegetative stage significantly attracted H. axyridis females in Y-tube olfactometer assays, while both females and males significantly avoided C. bipinnata during the flowering stage. Additionally, females lived significantly longer when offered 5 C. bipinnata flowers daily compared to those with no food source. Moreover, providing C. bipinnata flowers in addition to aphids (in deprivation or ad libitum) also significantly increased egg production of H. axyridis. Furthermore, in greenhouse pepper production, the introduction of C. bipinnata increased the colonization rate of H. axyridis released in the early stages, thus achieving effective pest control in the short term. In the long term, incorporating C. bipinnata helped sustain multiple developmental stages of H. axyridis populations, accelerating pest suppression and enhancing pepper yield throughout the entire production cycle.

功能性植物通过增加害虫天敌的数量，在植物保护中发挥着关键作用。作为伴生植物利用，是保护生物防治的重要组成部分。系统分析候选伴生植物的生态功能对于有效地吸引和维持天敌，从而促进生物防治策略至关重要。摘要本研究全面考察了石竹对野田鼠嗅觉行为、寿命和存活的影响，并评价了石竹对野田鼠种群维持和害虫防治的作用。与无伴生植物相比，y管嗅测结果表明，营养期的双羽石楠叶片显著吸引雌蜂，而花期的雌雄双羽石楠叶片均显著避开雌蜂。此外，当提供5 C时，雌性的寿命明显更长。与那些没有食物来源的相比，碧羽塔每天都会开花。此外，除提供蚜虫外，还提供双羽石楠花（剥夺或随意提供）也显著增加了毛蚜的产卵量。此外，在温室辣椒生产中，引入双峰锥虫提高了前期释放的灰蚜定殖率，在短期内达到了有效的防治效果。从长期来看，在辣椒生产的整个生产周期中，加入双羽石斛有助于维持红毛蚜种群的多个发育阶段，加速害虫的抑制和提高产量。

Drought stress severely inhibits the growth and production of winter wheat, particularly after anthesis. To mitigate these effects, this study evaluated the impact of intermittent water deficit priming on physiological and yield-related traits of winter wheat under subsequent drought stress, based on a two-year experiment. Intermittent moderate water deficit priming (PID2) significantly increased photosynthetic rate (P_n) and stomatal conductance, resulting in higher dry matter accumulation and relative growth rate. Moreover, compared to non-primed plants, PID2 improved dry matter translocation efficiency and its contribution to grain by 42.3 % and 23.0 %, respectively, thereby increasing yield by 27.1 %. Additionally, PID2 and persistent mild water deficit priming (PPD1) improved root distribution in the middle and lower soil layers, enhancing nitrogen uptake, as well as grain nitrogen and protein accumulation. Nitrogen use efficiency for yield under PID2 and PPD1 treatments increased by 12.5 % and 12.2 %, respectively, compared to non-primed plants. The TOPSIS assessment indicated that PID2 enhanced drought tolerance in wheat most effectively, making it a promising water management strategy for mitigating post-anthesis stress.

干旱胁迫严重抑制冬小麦的生长和产量，特别是在花期后。为了减轻这些影响，本研究基于一项为期两年的试验，评估了干旱胁迫下间歇性水分亏缺启动对冬小麦生理和产量相关性状的影响。间歇中度亏水处理（PID2）显著提高了叶片光合速率（Pn）和气孔导度，提高了叶片干物质积累和相对生长速率。与未处理的植株相比，PID2处理的干物质转运效率和对籽粒的贡献分别提高了42.3%和23.0%，产量提高了27.1%。此外，PID2和持续轻度水分亏缺启动（PPD1）改善了中下层土壤根系分布，提高了氮素吸收、籽粒氮素和蛋白质积累。与未处理相比，PID2和PPD1处理对产量的氮素利用效率分别提高了12.5%和12.2%。TOPSIS评价结果表明，PID2对小麦抗旱性的提高最为有效，是一种很有前景的缓解花后胁迫的水分管理策略。

Non-destructive detection of spotted wing Drosophila infestation in blueberry fruit using hyperspectral imaging technology 高光谱成像技术无损检测蓝莓果实斑翅果蝇侵染

Spotted Wing Drosophila (SWD) infestation in blueberries presents a significant threat to blueberry industries due to yield loss and quality safety issues during the postharvest process, where infested fruit is zero-tolerated. Current detection methods require destructive sampling, which is time-consuming and labor-intensive. Therefore, they are not suitable for high-volume inspection of individual products during postharvest handling. This study presents an innovative hyperspectral imaging-based approach to detect SWD infestation in highbush blueberry fruit. Two benchtop hyperspectral imaging systems in reflectance mode, operating in the visible-near-infrared (Vis-NIR, 400–1000 nm) and short-wavelength infrared (SWIR, 900–1700 nm) ranges, respectively, were in-house assembled for acquiring images of 945 (including 706 healthy and 235 infested) blueberry samples hand-picked from orchards. Hyperspectral imagery was processed to segment blueberries and extract mean spectra from individual samples. Infested blueberries showed lower spectral reflectance in the region of 750–1350 nm than normal samples. Baseline models were built using six different classifiers for sample classification, and the models based on partial least squares discriminant analysis (PLS-DA) yielded the best overall accuracy of 90.2 % and 92.5 % for the Vis-NIR and SWIR systems, respectively, with the corresponding recall rates of 74.2 % and 80.6 % for infested fruit. Three alternative modeling pipelines were proposed by implementing oversampling of the minority infested fruit class and waveband selection, through an exhaustive search for optimal methods, resulting in improved detection performance. Among the optimization strategies, oversampling proved more effective than waveband selection for enhancing model performance, and their combination (oversampling followed by waveband selection) yielded the best classification, with PLS-DA remaining the best classifier. The Vis-NIR and SWIR systems achieved the best overall accuracies of 93.7 % and 97.2 %, respectively, with the corresponding recall rates of 85.9 % and 95.7 % for infested fruit. This research showed that hyperspectral imaging, especially in the SWIR range, was useful for rapid, non-destructive detection of SWD infestation in blueberry fruit.

斑翅果蝇（SWD）在蓝莓中的侵染对蓝莓产业构成了重大威胁，因为在采后过程中，受侵染的果实是零容忍的，因此会造成产量损失和质量安全问题。目前的检测方法需要破坏性采样，耗时耗力。因此，它们不适合在采后处理期间对单个产品进行大批量检查。本研究提出了一种创新的基于高光谱成像的方法来检测高丛蓝莓果实中的SWD侵染。在室内组装了两套反射模式的台式高光谱成像系统，分别工作在可见光-近红外（Vis-NIR, 400-1000 nm）和短波红外（SWIR, 900-1700 nm）范围内，用于采集945个果园采摘的蓝莓样本（包括706个健康蓝莓样本和235个感染蓝莓样本）的图像。对高光谱图像进行分割，提取蓝莓样品的平均光谱。侵染蓝莓在750 ~ 1350 nm波段的光谱反射率较正常蓝莓低。采用6种不同的分类器建立基线模型进行样本分类，基于偏最小二乘判别分析（PLS-DA）的模型对Vis-NIR和SWIR系统的总体准确率最高，分别为90.2%和92.5%，对侵染水果的召回率分别为74.2%和80.6%。通过穷举搜索优化方法，提出了对少数侵染水果类进行过采样和选择波段的三种建模管道，提高了检测性能。在优化策略中，过采样比波段选择更有效地提高了模型的性能，它们的组合（过采样+波段选择）产生了最好的分类器，PLS-DA仍然是最好的分类器。Vis-NIR和SWIR系统的总体准确率最高，分别为93.7%和97.2%，相应的召回率分别为85.9%和95.7%。研究表明，高光谱成像，特别是在SWIR范围内，可用于快速、无损地检测蓝莓果实中SWD的侵害。
