近日，广东省农业科学院果树研究所助理研究员刘海伦、副研究员严倩和黄华团队在荔枝抗霜疫病分子调控研究方面取得新进展，揭示了荔枝Hap3-_LcOMT1_-PTOX调控模块介导的抗霜疫病机制。相关成果在线发表于《分子园艺》（_Molecular Horticulture_）。 ![Image

litchii_）引起，高温高湿条件下易暴发，当前田间防控主要依赖化学杀菌剂，长期大量使用易导致病原菌抗药性、农药残留及生态风险。因此，发掘抗病种质、解析内在抗性调控机制，并据此培育抗病品种或开发绿色防控物质，是产业亟待解决的核心问题。 研究团队依托国家荔枝种质资源圃（广州），对全球288份荔枝种质开展连续两年抗性评价，筛选出稳定高抗种质“裕荣”。通过广靶代谢组分析，在荔枝中鉴定到木脂素类代谢物——鬼臼毒素（PTOX）。体外抑菌试验及离体果实、叶片接种试验均证实PTOX可显著抑制荔枝霜疫霉菌增殖，电镜观察显示其能破坏菌丝及孢子囊的超微结构。同时，抗病种质“裕荣”叶片中PTOX本底含量远高于感病种质“桂味”，且侵染后病斑处出现PTOX特异性累积。 进一步转录组联合分析锁定苯丙烷通路中PTOX合成的关键限速基因 _LcOMT1_。群体序列分析显示其启动子存在3种单倍型：感病品种仅携带Hap1，而“裕荣”为Hap2\u002FHap3杂合基因型；其中Hap3启动子区含773 bp大片段插入，该片段富集多个抗病响应元件，可增强 _LcOMT1_ 转录活性。利用团队前期建立的荔枝原位发根转化方法进行基因功能验证，发现超表达 _LcOMT1_ 或Hap3单倍型均可提高PTOX含量并降低病情指数。 基于上述结果，研究团队提出Hap3?_LcOMT1_?PTOX调控模块介导荔枝抗霜疫病的新机制，为荔枝抗病分子育种、植物源生物防控技术研发及耐贮性改良提供了重要基因资源和理论依据。 相关论文信息：https:\u002F\u002Fdoi.org\u002F10.1186\u002Fs43897-026-00257-4

downy blight in _Litchi chinensis_ Sonn. via integrated metabolomics and transcriptomics”的研究论文。果树所为第一完成单位，刘海伦博士为第一作者，严倩副研究员、黄华副研究员为论文共同通讯作者。\n\n荔枝霜疫病主要由卵菌 _Peronophythora litchii_ 引起，在高温高湿环境下极易暴发，当前田间防控严重依赖化学杀菌剂，但长期大量用药易产生病原菌抗药性、农药残留及生态环境风险。培育抗病品种、发掘绿色防控物质并解析其内在抗性调控机理，是当前亟待解决的关键问题。\n\n研究团队依托国家荔枝种质资源圃（广州），对全球288份荔枝种质开展连续两年抗性评价，筛选出稳定高抗种质“裕荣”。利用该种质开展广靶代谢组分析，成功在荔枝中鉴定出木脂素类代谢物鬼臼毒素（Podophyllotoxin, PTOX）。体外抑菌与离体果实和叶片接种试验均证实其可抑制荔枝霜疫霉菌增殖，电镜观察显示其能破坏菌丝及孢子囊超微结构。此外，PTOX含量在抗病种质“裕荣”叶片的本底含量远高于感病种质“桂味”，且侵染后在病斑处特异性累积。\n\n进一步进行转录组联合分析锁定苯丙烷通路中PTOX合成关键限速基因 _LcOMT1_。群体序列分析显示其启动子存在3种单倍型，感病品种仅携带Hap1，“裕荣”为Hap2\u002FHap3杂合基因型；Hap3单倍型启动子区存在773bp大片段插入，含有多个抗病响应元件，可增强 _LcOMT1_ 转录活性。利用团队前期构建的荔枝原位发根转化方法（Horticultural Plant Journal, 2025, 11(4): 1699-1702），开展基因功能验证，发现超表达 _LcOMT1_ 或Hap3单倍型均可提升PTOX含量并降低病情指数。基于上述结果，研究提出了“Hap3-_LcOMT1_-PTOX”调控模块介导荔枝抗霜疫病，为荔枝抗病分子育种、植物源生物防控技术研发及耐贮性研究提供基因资源与理论支撑。\n\n研究得到广东省种业振兴专项资金（2025-NBH-00-001）和广东省农业科学院人才引进启动项目（R2021YJ-YB1005）资助。\n\n论文链接：https:\u002F\u002Fdoi.org\u002F10.1186\u002Fs43897-026-00257-4\n\n![Image

spp.)不仅是家喻户晓的热带、亚热带水果，也是我国南方地区重要的经济作物。根据联合国粮农组织（FAO）发布的统计数据，2024年我国的香蕉种植面积为32.55万公顷，总产量1210.11万吨，是世界上第二大香蕉生产国。我国的香蕉生产主要分布在广东、广西、云南、海南、福建和台湾等省(区)。目前我国乃至全世界的香蕉生产面临多种病虫害的威胁，其中由土传真菌(_Foc_)引起的毁灭性病害—香蕉镰刀菌枯萎病是首要病害。由于在病区缺乏行之有效的生物、化学防治方法，该病的防治在很大程度上依赖于抗\u002F耐病品种的选育。\n\n[国家园艺种质资源库](http:\u002F\u002Fwww.nhgrc.cn\u002F)荔枝香蕉分库参建单位广东省农业科学院果树研究所利用国家荔枝香蕉种质资源圃(广州)保存的香蕉资源进行种质创制，通过广粉1号粉蕉(ABB)×野生长梗蕉(BB)杂交，并从杂交后代中鉴定到抗病株系，突破性培育出抗枯萎病、抗逆且优质高产特色粉蕉新品种—粉杂1号(苹果蕉)。围绕粉杂1号的推广应用开展配套技术研发，主要包括组培快繁和育苗技术、优质高产栽培技术和常温采后处理技术等，为新品种的推广应用提供有力技术支撑。经农业农村部科技发展中心组织专家评价，技术总体处于国际领先水平。\n\n“抗枯萎病特色粉蕉新品种的选育及配套技术”克服香蕉抗病品种选育方法和抗病品种的类型相对单一、缺乏综合性状优异的香蕉品种、粉蕉的种植和销售未能实现跨区域发展等问题，和其他4项技术（分属水稻种植、畜禽疫病防控和水果加工等领域）一起入选2026年广东省重大引领性技术。\n\n![Image

necrotrophic pathogen whose destructive growth is typically studied under conditions that rapidly generate visible disease. Yet symptomless associations are well documented, the fungal and host processes operating before widespread tissue collapse remain poorly resolved. We developped an intact Arabidopsis thaliana seedling pathosystem that extends the interval between infection establishment and widespread visible disease. Fungal colonization was quantified using qPCR and a constitutively bioluminescent reporter strain, together with longitudinal plant phenotyping, hormone profiling and multiscale fluorescence microscopy. Substantial fungal colonization occurred while seedlings remained largely green and continued to grow, whereas robust whole seedling accumulation of salicylic and jasmonic acids occurred later. During this interval, B. cinerea displayed diverse tissue-associated infection morphologies. At individual contact sites, fungal walls showed heterogeneous exposure of chitin-associated epitopes, while host cells exhibited focal plasma-membrane polarization toward fungal contact sites, together with cortical actin reorganization. These results show that the interval preceding widespread visible disease is an active and spatially heterogeneous interaction state, in which substantial fungal development and highly organized local host responses are already established. Intact seedlings therefore provide a powerful system for resolving plant-pathogen interactions that are largely obscured in rapid disease assays.","灰葡萄孢（Botrytis cinerea）是一种死体营养型病原菌，其破坏性生长通常在迅速产生可见病害的条件下进行研究。然而，无症状关联已有充分记载，在组织大面积崩溃之前真菌与宿主所进行的过程仍鲜有阐明。我们建立了一个完整的拟南芥（Arabidopsis thaliana）幼苗病理系统，延长了侵染建立与大面积可见病害之间的时间间隔。利用qPCR和组成型生物发光报告菌株对真菌定殖进行定量，并结合纵向植物表型分析、激素谱分析和多尺度荧光显微镜。在幼苗大部分仍保持绿色并持续生长期间，真菌已发生大量定殖，而整株幼苗中水杨酸和茉莉酸的大量积累则出现较晚。在此期间，灰葡萄孢表现出多样的组织相关侵染形态。在单个接触位点，真菌细胞壁显示出几丁质相关表位的异质性暴露，而宿主细胞则表现出质膜向真菌接触位点的局灶性极化，并伴随皮层肌动蛋白重组。这些结果表明，大面积可见病害出现之前的间隔期是一个活跃且空间异质的互作状态，其中大量的真菌发育和高度有序的局部宿主反应已经建立。因此，完整幼苗为解析在快速病害测定中大多被掩盖的植物-病原菌互作提供了一个强有力的系统。","bioRxiv
