Plant（分子植物）》，首次揭示“高温感知—糖信号传递—休眠解除”这条分子通路，为培育耐高温优质水稻、保障水稻稳产提供了全新理论依据与技术路径。\n\n**高温怎样策反“休眠管理员”**\n\n穗发芽过去更多是小麦的麻烦：籽粒休眠期短，麦壳又薄，碰上连续阴雨，三两天就发芽。农民口中的“烂场雨”不少说的就是它。可这几年，这桩麻烦事开始频频出现在水稻田里。今年发表于《Journal of Integrative Agriculture（农业科学学报）》的一篇综述提醒：气候变暖与极端降水，使穗发芽从局部偶发性问题，升级为水稻稳产高产的系统性风险。\n\n![Image 2:

Plant（分子植物）》发表文章评述这项研究，称赞OSK3-OsbZIP58模块作为糖感知调控枢纽，首次系统阐明了高温通过蔗糖耗竭驱动水稻穗发芽的完整分子通路，为抗穗发芽育种提供了极具价值的靶点。\n\n**把籼稻的“耐热本事”借给粳稻**\n\n穗发芽现象背后的机制搞清楚了。高温一来，水稻到底该怎么防？\n\n团队调出RiceVarMap数据库中4677份水稻种质资的序列，对OsbZIP58关键基因做分型比对，结果发现，这个“休眠管理员”在自然界有两种单倍型（Hap）分化版本——Hap1多见于粳稻，Hap2多见于籼稻。两个版本“执勤”能力也不一样：籼稻里的Hap2休眠维持得更牢，耐高温、抗穗发芽；粳稻里的Hap1遇上高温容易失守。\n\n这一发现，给籼稻和粳稻添了新的区分标签。“这与籼稻、粳稻各自的‘脾气’是相对应的。”朱英说，籼稻耐热、耐湿，主要分布在低纬度低海拔的南方；粳稻耐寒，更多分布在北方及南方高海拔山区。千百年来，农人依照表型反复选择“更好的那一株”，事实上已经把两种基因型分别固定下来，只是此前没人知道背后的原理。\n\n让粳稻也学会籼稻身上那套“耐热”的本领，在全球变暖的今天变得重要起来，对浙江尤其重要。\n\n据统计，浙江水稻种植面积约 1000万亩，籼粳杂交稻占比超50%。籼粳杂交是浙江高产攻关、超级稻培育的重要方向。“制种田里收回来的种子，是给下一季杂交稻生产用的。”朱英告诉记者一组数据，一旦穗发芽，上百斤种子里，可能只剩几十斤能正常萌发，“农民种下去是要误农时的。”\n\n更关键的是，这份耐热的差距，只落在Hap1与Hap2的差异上，一条精准的籼粳杂交技术路线随之浮现：通过碱基编辑器这把“基因手术刀”，定向改造粳稻的Hap1型为Hap2型。相比传统育种靠表型一轮轮回交“清洗”遗传背景，它干净又利落。\n\n从找基因到改品种，也指向一种新的育种路径：测序列、做表型鉴定，搞清哪些基因对应哪些性状，在品种设计阶段就把想要的抗性基因“装”进去——用“设计育种”替代“经验育种”。\n\n“这两年有个词叫‘韧性农业’。”朱英说，高温、低温、冰雹等环境因子造成的“非生物逆境”，是团队长期攻坚的方向，“让种子‘刀枪不入’是不可能的，但别人绝收时我们还能保住五成产量，就是我们的目标。”\n\n**让籼、粳两朵稻花同时开**\n\n守住种子的休眠能力，只是团队设计育种的第一步。在全球变暖背景下，业内已有共识：高温是导致水稻减产的主要驱动因素之一。这份压力真正落到田间，首当其冲的其实是花。\n\n水稻虽是自花授粉作物，但要利用杂种优势，就得让父本、母本的花期相遇。偏偏稻花对气温极为敏感：抽穗扬花那几天最怕两个极端，如果日平均气温连续3天低于23℃或者日最高气温冲过35℃，父母本原有的开花节奏就会被打乱，你开你的、我开我的，结实率跟着往下掉。\n\n高温诱发的穗发芽这道“种子难关”已过，花期的考验，朱英团队同样想闯。\n\n朱英说，稻花很特别，一生只开一次，一次仅30至60分钟。更特别的是，籼稻和粳稻的“作息”还对不上：籼稻上午10时前后开花，粳稻往往要等到上午11时甚至12时。以粳稻作母本时，它的花还没开，籼稻父本的花粉早已散完，“过去靠人工赶花，费力不说，改良的空间其实也很大。”\n\n契机，恰恰藏在“休眠管理员”的研究里。因为研究OsbZIP58，团队常年在田里一笔笔地记录水稻开花。记得多了，他们发现稻花基部有一对仅芝麻大小的浆片，平时瘪着；花将开时，浆片迅速吸水膨胀，“啪”地撑开内外稃；约一小时后失水，花又合上。顺着这条线索，他们找到了一个只在浆片中表达、掌握水稻开花“开关”的基因OsbHLH091——把这个基因敲除，水稻颖壳从此紧闭，成了彻底的闭花授粉。\n\n“敲除就永远不打开”的特性，还意外打开了另一扇门：对高粱等异花授粉、串粉严重、育种必须套袋的作物来说，能让它“关上门、只认自家花粉”的开关，价值更大。\n\n更有意思的是，这一基因在籼稻与粳稻之间同样存在单倍型（Hap）分化。把籼型版本转进粳稻，粳稻提前开花；把粳型版本转进籼稻，籼稻则延后开花。调控它，就能换来制种最需要的“花时同步”。相关成果近日发表于国际权威期刊《The Plant Cell（植物细胞）》。\n\n眼下，团队已用这套思路创制出一批新的不育系材料，把耐高温、抗穗发芽等有利基因聚在一起，并开始组配杂交组合。“基础研究先行，应用已经在路上。”朱英说，让每一粒稻谷在该睡的时候睡足、该开花的时候开花，说到底，守的是一碗饭的安稳。\n\n“转载请注明出处”\n\n责任编辑：龚之晶","潮新闻（浙江日报）·2026年9月30日","2026-09-30T00:00:00Z","报道",10,false,86,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},24,25,19,12,6,1,"首次揭示高温感知—糖信号—休眠解除分子通路，兼具理论突破与设计育种应用路径，值得进入每日精选。",[25],{"name":10,"url":6},[27,28,29,30,31],"种业振兴","水稻育种","设计育种","耐高温水稻","籼粳杂交",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"A1","rice","水稻","\u002Ftopic\u002Ffield-crops\u002Frice","A",[],{"status":40,"locked":14,"version":41,"method":42,"evidence":43},"classified","2026-10-22.2","rules",{"candidates":44,"agricultural_evidence":46},[45,50,57],{"code":33,"score":20,"supported":46,"title":47,"abstract":48,"tags":49},true,[35],[35],[28],{"code":51,"score":52,"supported":46,"title":53,"abstract":54,"tags":56},"A5",3,[],[55],"高粱",[],{"code":58,"score":22,"supported":14,"title":59,"abstract":60,"tags":61},"F1",[],[],[27],[63,64],"浙江省农科院

of Advanced Research）》上。\n\nGSE9基因多存在于粳稻，调控粒型形成圆粒，敲除该基因籽粒变为类似籼稻的细长粒表型，过表达则籽粒更圆、粒重增加。然而，这一现象背后的分子调控网络尚不清楚，表性调控背后存在哪些代谢、品质的变化也未知。\n\n研究团队借助转录组‑代谢组‑蛋白质组多组学结合机器学习KANMB技术，系统解析了穗发育过程中GSE9介导的籽粒外观表型与内在品质成分的调控网络，发现GSE9主要协同调控次级代谢与淀粉代谢，敲除GSE9会引发全基因组转录-翻译解偶联，这种全局性分子扰动伴随代谢与表型改变，表明基因编辑除靶标性状外会产生广泛系统效应。\n\n该研究得到海南省重点研发计划、中国农业科学院科技创新工程等项目支持。","中国农业科学院

金秋时节，稻浪飘香。近日，全省籼粳杂交稻新品种现场观摩会在海盐召开，现场展示了43个籼粳交水稻品种，其中对8个优势籼粳杂交稻品种、7个籼粳杂交稻新品种进行了集中推介。\n\n活动集中展示了43个籼粳杂交水稻品种。经专家现场测产、性状评估，浙粳优1578、华中优9326、浙禾优127等8个丰产性好、综合性状优良的籼粳杂交水稻品种被重点推介。目前，这些品种已在省内外大规模推广种植。\n\n“种子就是粮食生产的‘芯片’。籼粳杂交品种的推出，能为我们大面积单产提升打下很好的品种底子，因为品种才是核心。籼粳杂交品种需要具备一定的综合抗性，比如抗病、抗虫，因为各地区的实际情况不同。所以这类品种的推广，能为大面积单产提升提供扎实的基础。”中国水稻研究所副研究员王亚梁表示。\n\n承担此次新品种种植的海盐示范基地，位于通元云飞农场。在该示范基地，记者看到籼粳杂交稻品种“浙禾优127”稻穗饱满、色泽青中泛黄，已处于成熟期。基地工作人员表示，该品种具有丰产性好、抗倒伏性强等突出优势。\n\n近年来，海盐加强农业科技创新推广力度，围绕“绿色、低碳、科技、示范”等要求，通过新品种、新技术的集中应用展示，使基地成为推广应用农业科技新成果的示范基地、技术超市和田间学校。\n\n“我们试种测产后，这款水稻亩产达到920斤，今年的长势依旧很好。”浙江省农作物新品种展示示范基地负责人、云飞农场负责人孙飞介绍，“这个品种有抗倒伏、耐高温的优点，长势挺拔，结实率高。一般的稻子亩产达到这么高时很容易倒伏，它就不会，农户就喜欢这种。”\n\n据了解，浙禾优系列品种由浙江勿忘农种业股份有限公司培育。“浙禾优系列是抗病性很好的水稻品种，不同地区的试种结果表明，今年白叶枯病比较严重，浙禾优在抗病性、尤其是抗白叶枯病方面表现特别突出。”浙江勿忘农种业股份有限公司水稻种业部经理湛立伟表示。\n\n目前，全省水稻种植面积约1000万亩，其中籼粳杂交稻种植面积超过50%。过硬的育种实力，为全省乃至全国粮食单产提升提供了有力支撑。此次活动不仅集中展示了长江中下游稻区在水稻育种创新领域的实力与成果，还通过深化产学研协同，为推进水稻种业高质量发展提供了重要平台。\n\n“浙江省的稻作技术，包括品种技术和栽培技术，在全国是领先的。比如我们的籼粳交品种，已经发展了接近20多年，这点就很厉害。”王亚梁表示，“下一步，要突出两个方向：优质稻优质、高产。以前都说先高产、后优质，现在要倒过来，优质的同时要实现高产。所以这两条是平行的——高产优质、优质高产，要协同发展，实现水稻大面积提产增效。”","海盐县人民政府

important staple crop, yet increasing climatic variability and abiotic stresses threaten yield stability and food security. Accelerating the genetic dissection of yield-related traits is therefore critical for developing climate-resilient rice cultivars. Methods In this study, we characterized the genetic diversity and genomic architecture of agronomically important traits in 188 advanced breeding lines (ABLs) developed at IGKV, India. Results and discussion We genotyped the ABLs using genotyping-bysequencing, and identified 87 high-quality, trait-informative single-nucleotide polymorphism markers distributed across all 12 rice chromosomes. STRUCTURE analysis revealed five genetically differentiated subgroups (SG1–SG5), comprising 59, 31, 36, 44, and 18 accessions, respectively, indicating substantial genetic stratification. Eight yield-associated agronomic traits were phenotypically evaluated and subjected them to genome-wide association analysis. In total, 34 marker– trait associations (MTAs) were detected, each explaining 2.00%–11.05% of phenotypic variance, consistent with a polygenic architecture. A notable QTL hotspot on chromosome 6 was identified, representing a promising genomic region for simultaneous improvement of multiple traits. Integrating population structure, genome-wide markers, and phenotypic data provides a robust framework for exploiting favorable alleles in Central Indian rice germplasm. These MTAs and the chromosome 6 hotspot warrant validation and may support marker-assisted, genomic selection, and genomics-assisted breeding for high-yielding, climate resilient rice cultivars.","引言 水稻是重要的主粮作物，但日益加剧的气候变率和非生物胁迫威胁着产量稳定性和粮食安全。因此，加快产量相关性状的遗传解析对于培育气候韧性水稻品种至关重要。方法 本研究对印度IGKV开发的188个高级育种品系（advanced breeding lines，ABLs）的农艺重要性状进行了遗传多样性和基因组结构表征。结果与讨论 我们采用测序基因分型（genotyping-by-sequencing）对ABLs进行基因分型，鉴定出87个高质量、性状信息丰富的单核苷酸多态性标记，分布于全部12条水稻染色体上。STRUCTURE分析揭示了5个遗传分化亚群（SG1–SG5），分别包含59、31、36、44和18份材料，表明存在显著的遗传分层。对8个产量相关农艺性状进行了表型评价，并进行了全基因组关联分析。共检测到34个标记–性状关联（marker–trait associations，MTAs），每个关联解释2.00%–11.05%的表型变异，符合多基因结构。在第6号染色体上鉴定到一个显著的QTL热点，代表了一个有望同时改良多个性状的基因组区域。整合群体结构、全基因组标记和表型数据，为挖掘印度中部水稻种质中的有利等位基因提供了稳健框架。这些MTAs和第6号染色体热点值得进一步验证，并可能支持标记辅助选择、基因组选择和基因组学辅助育种，以培育高产、气候韧性的水稻品种。","Frontiers in Sustainable Food Systems","论文",78,{"impact":126,"substance":79,"depth":124,"authority":208,"freshness":13,"relevant":22,"comment":284},"印度水稻育种系GWAS研究，方法规范、数据扎实，对分子育种有参考价值，但属区域性科研进展，公共影响有限。",[286],{"name":280,"url":277},[27,28,288,289,290],"气候韧性农业","全基因组关联分析","分子标记辅助育种",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":294},{"candidates":295,"agricultural_evidence":46},[296,300,305,311,317],{"code":33,"score":126,"supported":46,"title":297,"abstract":298,"tags":299},[34],[35,34],[28],{"code":100,"score":21,"supported":46,"title":301,"abstract":302,"tags":304},[],[87,303],"food security",[],{"code":179,"score":21,"supported":46,"title":306,"abstract":307,"tags":310},[],[308,309],"基因组选择","genomic selection",[],{"code":58,"score":312,"supported":46,"title":313,"abstract":314,"tags":316},4,[],[315],"germplasm",[27],{"code":318,"score":22,"supported":14,"title":319,"abstract":320,"tags":321},"H7",[],[],[288],[323,324],"IGKV 水稻 育种系","水稻 染色体6 QTL","IGKV水稻育种系-4789","10.3389\u002Ffsufs.2026.1981880",{"doi":326,"openalex_id":328,"authors":329,"venue":280,"cited_by_count":113,"oa_url":277,"card":361,"direction":365,"ingested_from":367},"W7221562552",[330,333,336,338,341,344,347,349,352,354,357,359],{"name":331,"orcid":332},"Abhinav Sao","https:\u002F\u002Forcid.org\u002F0000-0003-1855-4688",{"name":334,"orcid":335},"Sunil Kumar Nair","https:\u002F\u002Forcid.org\u002F0000-0003-1662-9439",{"name":337,"orcid":8},"Deepak Gauraha",{"name":339,"orcid":340},"Hemant Sahu","https:\u002F\u002Forcid.org\u002F0009-0002-0017-0790",{"name":342,"orcid":343},"Saurabh Pandey","https:\u002F\u002Forcid.org\u002F0000-0002-9142-1788",{"name":345,"orcid":346},"Tarun Kumar Thakur","https:\u002F\u002Forcid.org\u002F0000-0001-9389-1292",{"name":348,"orcid":8},"Prafull Kumar",{"name":350,"orcid":351},"Ritu R.
