    在本文中,提供了广泛的文献综述,研究了在全球对小麦的需求不断增长以及环境变化和病原体移动的威胁下,小麦对真菌疾病的耐受性的重要性。目前疾病管理全面依赖农用化学品对食品安全和环境构成风险,加剧了杀菌剂耐药性的出现。虽然小麦的抗性性状可以提供一定的保护,这些特征并不能保证在剧烈或中度疾病发展期间完全没有损失。此外,将单个抗性基因引入小麦单一栽培会对病原体种群施加选择压力。这些缺点可以通过种植耐性小麦品种来解决或至少减轻。这方面的研究表明,某些小麦品种,易患严重传染病,仍然能够实现高产量。通过对现有文献的分析,本文探讨了小麦耐性的表现和量化,讨论其对综合疾病管理和育种策略的影响。此外,本文讨论了病原体-植物宿主系统中耐受性的生态和进化方面,强调其提高小麦生产力和可持续性的潜力。
    In this paper, an extensive review of the literature is provided examining the significance of tolerance to fungal diseases in wheat amidst the escalating global demand for wheat and threats from environmental shifts and pathogen movements. The current comprehensive reliance on agrochemicals for disease management poses risks to food safety and the environment, exacerbated by the emergence of fungicide resistance. While resistance traits in wheat can offer some protection, these traits do not guarantee the complete absence of losses during periods of vigorous or moderate disease development. Furthermore, the introduction of individual resistance genes into wheat monoculture exerts selection pressure on pathogen populations. These disadvantages can be addressed or at least mitigated with the cultivation of tolerant varieties of wheat. Research in this area has shown that certain wheat varieties, susceptible to severe infectious diseases, are still capable of achieving high yields. Through the analysis of the existing literature, this paper explores the manifestations and quantification of tolerance in wheat, discussing its implications for integrated disease management and breeding strategies. Additionally, this paper addresses the ecological and evolutionary aspects of tolerance in the pathogen-plant host system, emphasizing its potential to enhance wheat productivity and sustainability.

    马铃薯(Solanumtuberosum)是世界范围内种植的主要农作物。为满足市场需求,育种计划的重点是增强重要的农业性状,例如抗病性和改善块茎的适口性。然而,虽然马铃薯块茎从研究中得到了很多关注,马铃薯浆果大多被忽视,因为它们的毒性水平和对食品生产部门缺乏有用性。一般来说,收获块茎后,它们在生产领域仍未使用。这些浆果是有毒的,由于高水平的糖生物碱,这可能会赋予一些有趣的生物活性。各种茄科植物的浆果含有生物活性次级代谢产物,表明马铃薯浆果可能含有类似的有价值的代谢物。因此,马铃薯浆果的可能应用,例如,在保护植物免受害虫和病原体侵害方面,以及它们抗炎的医学开发,抗癌,和抗真菌特性,是合理的。马铃薯浆果中有价值的化合物的存在也可以通过为否则丢弃的农业侧流提供新的用途而有助于生物经济。在这里,我们回顾了这些浆果用于提取可用于生产药物和植物保护产品的化合物的潜在用途。
    Potato (Solanum tuberosum) is a major agricultural crop cultivated worldwide. To meet market demand, breeding programs focus on enhancing important agricultural traits such as disease resistance and improvement of tuber palatability. However, while potato tubers get a lot of attention from research, potato berries are mostly overlooked due to their level of toxicity and lack of usefulness for the food production sector. Generally, they remain unused in the production fields after harvesting the tuber. These berries are toxic due to high levels of glycoalkaloids, which might confer some interesting bioactivities. Berries of various solanaceous species contain bioactive secondary metabolites, suggesting that potato berries might contain similarly valuable metabolites. Therefore, possible applications of potato berries, e.g., in the protection of plants against pests and pathogens, as well as the medical exploitation of their anti-inflammatory, anticarcinogenic, and antifungal properties, are plausible. The presence of valuable compounds in potato berries could also contribute to the bioeconomy by providing a novel use for otherwise discarded agricultural side streams. Here we review the potential use of these berries for the extraction of compounds that can be exploited to produce pharmaceuticals and plant protection products.

    自20世纪中叶以来,种植者一直依赖链霉素和土霉素作为其植物疾病库的一部分的特异性和功效。随着气候变化加剧植物细菌流行,这些抗生素的成功仍然受到威胁。我们强烈依赖某些抗生素治疗破坏性疾病,最终让位于耐药性的发展。尽管植物农业中的抗生素占美国抗生素总使用量的不到0.5%,人类仍然必须继续监控使用情况,环境残留物,和细菌种群的耐药性。这篇评论概述了历史和使用,抵抗和缓解,regulation,环境影响,以及植物农业中抗生素的经济学。细菌问题,例如佛罗里达州柑橘生产中正在进行的黄龙病(柑橘绿化)流行,可能需要抗生素来进行适当的控制。因此,通过使用更有针对性的应用方法来保持我们当前抗生素的功效,比如躯干注射,应该是一个主要的焦点。
    Growers have depended on the specificity and efficacy of streptomycin and oxytetracycline as a part of their plant disease arsenal since the middle of the 20th century. With climate change intensifying plant bacterial epidemics, the established success of these antibiotics remains threatened. Our strong reliance on certain antibiotics for devastating diseases eventually gave way to resistance development. Although antibiotics in plant agriculture equal to less than 0.5% of overall antibiotic use in the United States, it is still imperative for humans to continue to monitor usage, environmental residues, and resistance in bacterial populations. This review provides an overview of the history and use, resistance and mitigation, regulation, environmental impact, and economics of antibiotics in plant agriculture. Bacterial issues, such as the ongoing Huanglongbing (citrus greening) epidemic in Florida citrus production, may need antibiotics for adequate control. Therefore, preserving the efficacy of our current antibiotics by utilizing more targeted application methods, such as trunk injection, should be a major focus.

    采用环保高效的方法控制食品腐败和作物病害已成为世界性的新趋势。在医学领域,已经开发了各种酶响应性控释药物制剂用于精确治疗。最近,这些材料和技术也已开始应用于食品保存和农业保护领域。本文综述了酶响应型控释材料在食品保鲜和作物保护领域的应用。它涵盖了由不同类型的酶引发的各种复合控释材料,并详细描述了它们的组成和结构,控释机制,和实际应用效果。酶响应材料已用于控制食源性病原体,真菌,和害虫。这些酶响应性控释材料表现出优异的靶向药物递送能力。与微生物或害虫接触时,材料的聚合物外壳被这些生物体分泌的酶降解,从而释放杀死或抑制生物体的药物。此外,已创建多酶敏感载体以提高递送系统的有效性和广谱。使用酶响应性控释材料的增加趋势在食品和农业中开辟了无数的可能性。
    The adoption of environmentally friendly and efficient methods to control food spoilage and crop diseases has become a new worldwide trend. In the medical field, various enzyme-responsive controlled-release drug formulations have been developed for precision therapy. Recently, these materials and techniques have also begun to be applied in the fields of food preservation and agricultural protection. This review of contemporary research focuses on applications of enzyme-responsive controlled-release materials in the field of food preservation and crop protection. It covers a variety of composite controlled-release materials triggered by different types of enzymes and describes in detail their composition and structure, controlled-release mechanisms, and practical application effects. The enzyme-responsive materials have been employed to control foodborne pathogens, fungi, and pests. These enzyme-responsive controlled-release materials exhibit excellent capabilities for targeted drug delivery. Upon contact with microorganisms or pests, the polymer shell of the material is degraded by secreted enzymes from these organisms, thereby releasing drugs that kill or inhibit the organisms. In addition, multi-enzyme sensitive carriers have been created to improve the effectiveness and broad spectrum of the delivery system. The increasing trend towards the use of enzyme-responsive controlled-release materials has opened up countless possibilities in food and agriculture.

    天然产物是由生物体产生的化合物,可分为两大类:初级代谢产物(PMs)和次级代谢产物(SMs)。植物PMs对植物生长和繁殖至关重要,因为它们直接参与活细胞过程,而植物SMs是直接参与植物防御和抗性的有机物质。SM分为三大类:萜类化合物,酚类和含氮化合物。SMs含有多种生物能力,可用作调味剂,食品添加剂,植物病害防治,加强植物对草食动物的防御,此外,它可以帮助植物细胞更好地适应生理应激反应。当前的审查主要集中在与意义有关的某些关键要素上,生物合成,分类,植物SMs主要类别的生化特征和医学/药物用途。此外,SMs在控制植物病害中的有用性,提高植物的抗性和作为潜在的天然,安全,本综述还报道了化学合成农药的生态友好替代品。
    Natural products are compounds produced by living organisms and can be divided into two main categories: primary (PMs) and secondary metabolites (SMs). Plant PMs are crucial for plant growth and reproduction since they are directly involved in living cell processes, whereas plant SMs are organic substances directly involved in plant defense and resistance. SMs are divided into three main groups: terpenoids, phenolics and nitrogen-containing compounds. The SMs contain a variety of biological capabilities that can be used as flavoring agents, food additives, plant-disease control, strengthen plant defenses against herbivores and, additionally, it can help plant cells to be better adapted to the physiological stress response. The current review is mainly focusing on certain key elements related to the significance, biosynthesis, classification, biochemical characterization and medical/pharmaceutical uses of the major categories of plant SMs. In addition, the usefulness of SMs in controlling plant diseases, boosting plant resistance and as potential natural, safe, eco-friendly substitutes for chemosynthetic pesticides were also reported in this review.

    虽然农业集约化和扩张是导致自然栖息地丧失和退化以及物种减少的主要因素,一些野生动物物种也受益于农业管理的栖息地。这可能导致人口密度高,对人类生计和野生动植物保护都产生影响。起重机是全世界15种的一组,受到农业实践的负面影响和积极影响。虽然有11个物种面临严重的种群下降,在过去的40年中,普通起重机(Grusgrus)和沙丘起重机(Gruscanadensis)的数量急剧增加。它们的增加与起重机在农作物上觅食的发生率更高有关,给农民造成经济损失。我们的目标是综合有关土地利用变化和起重机种群的双边影响的科学知识。我们对同行评审的有关农业与起重机相互作用(n=135)以及农作物在起重机饮食中的重要性(n=81)的出版物进行了系统的文献综述。农作物占所有鹤类饮食的相当一部分(平均为37%,最常见的是玉米(玉米)和小麦(小麦))。仅在所有农业-起重机相互作用的10%中发现了作物损害,尽管三分之一的相互作用包括起重机在农田上觅食。使用概念框架分析,我们确定了农业-起重机相互作用的两个主要途径:(1)栖息地丧失对依赖于特定栖息地的起重机物种的负面影响,(2)扩大农业栖息地,提供丰富的食物,有利于机会性起重机物种。鹤类能够适应农业土地利用变化的程度可能是解释其种群反应的重要因素。我们得出的结论是,多目标管理需要在景观尺度上结合土地节约和土地共享策略。为了支持可行的起重机种群,同时保证可持续的农业生产,有必要纳入不同利益攸关方的观点,并相应地简化保护举措和农业政策。
    While agricultural intensification and expansion are major factors driving loss and degradation of natural habitat and species decline, some wildlife species also benefit from agriculturally managed habitats. This may lead to high population densities with impacts on both human livelihoods and wildlife conservation. Cranes are a group of 15 species worldwide, affected both negatively and positively by agricultural practices. While eleven species face critical population declines, numbers of common cranes (Grus grus) and sandhill cranes (Grus canadensis) have increased drastically in the last 40 years. Their increase is associated with higher incidences of crane foraging on agricultural crops, causing financial losses to farmers. Our aim was to synthesize scientific knowledge on the bilateral effects of land use change and crane populations. We conducted a systematic literature review of peer-reviewed publications on agriculture-crane interactions (n = 135) and on the importance of agricultural crops in the diet of cranes (n = 81). Agricultural crops constitute a considerable part of the diet of all crane species (average of 37%, most frequently maize (Zea mays L.) and wheat (Triticum aestivum L.)). Crop damage was identified in only 10% of all agriculture-crane interactions, although one-third of interactions included cranes foraging on cropland. Using a conceptual framework analysis, we identified two major pathways in agriculture-crane interactions: (1) habitat loss with negative effects on crane species dependent on specific habitats, and (2) expanding agricultural habitats with superabundant food availability beneficial for opportunistic crane species. The degree to which crane species can adapt to agricultural land use changes may be an important factor explaining their population response. We conclude that multi-objective management needs to combine land sparing and land sharing strategies at landscape scale. To support viable crane populations while guaranteeing sustainable agricultural production, it is necessary to include the perspectives of diverse stakeholders and streamline conservation initiatives and agricultural policy accordingly.

    晚枯病(LWD)是一种在玉米发育后期爆发的血管性枯萎病,通常在开花期间或之后。疾病的病原体,土壤和种子传播的真菌,稻瘟病,在埃及造成重大经济损失,以色列,西班牙,葡萄牙,和印度。自从1960年代初在埃及发现以来,该疾病的知识库得到了显着扩展。这包括病原体及其作用方式的基本信息,疾病症状和损害,研究和监测病原体的方法,最重要的是,控制策略,以抑制M.maydis和减少其对商业玉米生产的影响。三种方法从所检查的各种控制方法中脱颖而出。首先,对化学农药的传统使用进行了广泛的研究。这种方法引起了人们的注意,在2018-2020年,即使在LWD的严重病例中,基于Azoxstrobin的可行且经济的治疗(单独或与其他杀真菌剂组合)也被证明是有效的。第二,近年来,用生态友好型生物和其他绿色协议代替化学处理的趋势变得越来越重要,并已经取得了重大成就。最后但并非最不重要的,当今应对LWD的主要策略是依靠抗性玉米基因型。在过去的二十年中,基于分子的诊断方法的引入以追踪和鉴定病原体标志着这一全球努力的重大进展。尽管如此,世界范围内的研究工作进展相对缓慢,因为这种疾病在世界大多数地区被认为是外来的和陌生的。本综述总结了LWD积累的知识,它的因果代理,和疾病的影响。将解决的另一个重要方面是对风险和知识差距的未来观点。
    Late wilt (LWD) is a vascular wilt disease that outbursts late in maize development, usually during or after flowering. The disease causal agent, the soil and seed-borne fungi, Magnaporthiopsis maydis, causes significant economic losses in Egypt, Israel, Spain, Portugal, and India. Since its discovery in the early 1960s in Egypt, the knowledge base of the disease was significantly expanded. This includes basic information on the pathogen and its mode of action, disease symptoms and damages, methods to study and monitor the pathogen, and above all, control strategies to restrain M. maydis and reduce its impact on commercial maize production. Three approaches stand out from the various control methods inspected. First, the traditional use of chemical pesticides was investigated extensively. This approach gained attention when, in 2018-2020, a feasible and economical treatment based on Azoxystrobin (alone or in combination with other fungicides) was proven to be effective even in severe cases of LWD. Second, the growing trend of replacing chemical treatments with eco-friendly biological and other green protocols has become increasingly important in recent years and has already made significant achievements. Last but not least, today\'s leading strategy to cope with LWD is to rely on resistant maize genotypes. The past two decades\' introduction of molecular-based diagnostic methods to track and identify the pathogen marked significant progress in this global effort. Still, worldwide research efforts are progressing relatively slowly since the disease is considered exotic and unfamiliar in most parts of the world. The current review summarizes the accumulated knowledge on LWD, its causal agent, and the disease implications. An additional important aspect that will be addressed is a future perspective on risks and knowledge gaps.
