Science》上。这是该团队继在国际首次解析十字花科作物感病基因介导的根肿病隐性广谱抗性后，在十字花科作物根肿病研究领域取得的又一突破性进展。\n\n根肿病是危害油菜、白菜、甘蓝等十字花科作物的共性重大土传病害，近年来在我国大范围流行，对油料和蔬菜生产造成重大损失。引起根肿病的病原根肿菌是一类具有动物行为的低等单细胞真核生物（原生动物），与已知植物病原物分类不同，其分子基础长期缺乏深入认识。RNAi是真核生物中广泛存在的一种基因调控现象，具有靶向性好、适用性广、环境友好等特点，作用机制多样，已广泛应用于农作物病虫害的抗性改良和绿色高效防控，但根肿菌是否具有RNAi系统、其作用机制如何长期未知。\n\n为此，研究团队聚焦根肿菌分子生物学及其侵染路径开展研究，首次发现了根肿菌中存在一套区别于经典RNAi调控的新模式，且侵染早期的根肿菌含有一种高分子多聚糖几丁质，是油菜根肿病绿色高效防控的理想靶标。研究团队通过RNAi技术干扰根肿菌不同生理小种的几丁质合成，成功阻断了根肿菌的早期侵染，实现了油菜根肿病的广谱抗性改良。上述研究打通了从病原基础机制解析、防控靶点挖掘到抗病材料创制的完整研究链条，丰富了真核生物RNAi机制多样性的理论认知，为十字花科根肿病广谱抗性改良和绿色高效防控提供了新的理论依据和技术路径。\n\n(单位:

Science》上。这是该团队继在国际首次解析十字花科作物感病基因介导的根肿病隐性广谱抗性后，在十字花科作物根肿病研究领域取得的又一突破性进展。\n\n根肿病是危害油菜、白菜、甘蓝等十字花科作物的共性重大土传病害，近年来在我国大范围流行，对油料和蔬菜生产造成重大损失。引起根肿病的病原根肿菌是一类具有动物行为的低等单细胞真核生物（原生动物），与已知植物病原物分类不同，其分子基础长期缺乏深入认识。RNAi是真核生物中广泛存在的一种基因调控现象，具有靶向性好、适用性广、环境友好等特点，作用机制多样，已广泛应用于农作物病虫害的抗性改良和绿色高效防控，但根肿菌是否具有RNAi系统、其作用机制如何长期未知。\n\n为此，研究团队聚焦根肿菌分子生物学及其侵染路径开展研究，首次发现了根肿菌中存在一套区别于经典RNAi调控的新模式，且侵染早期的根肿菌含有一种高分子多聚糖几丁质，是油菜根肿病绿色高效防控的理想靶标。研究团队通过RNAi技术干扰根肿菌不同生理小种的几丁质合成，成功阻断了根肿菌的早期侵染，实现了油菜根肿病的广谱抗性改良。上述研究打通了从病原基础机制解析、防控靶点挖掘到抗病材料创制的完整研究链条，丰富了真核生物RNAi机制多样性的理论认知，为十字花科根肿病广谱抗性改良和绿色高效防控提供了新的理论依据和技术路径。\n\n(单位:

能够提高棉花组织中的角鲨烯积累水平，并促进棉花生长发育，改善干旱和碱胁迫耐受性，为棉花遗传改良与副产物高值化利用提供了新思路。相关成果以“GhSQS1-mediated squalene accumulation coordinates cotton development and stress resilience”为题，发表于国际植物科学期刊《实验植物学杂志（Journal of Experimental Botany）》上。\n\n棉花是重要的天然纤维作物，其棉叶、棉籽等副产物也具有较高的开发利用潜力。角鲨烯是一种具有较高应用价值的三萜类化合物，在化妆品、营养保健等领域具有广泛应用，同时也是植物甾醇及其他三萜类化合物生物合成的重要前体。然而，角鲨烯生物合成与棉花生长发育及逆境适应之间的关系尚不明确，其潜在调控机制仍有待深入研究。\n\n该研究发现适宜浓度的角鲨烯可促进棉花主根伸长和离体胚珠发育，并鉴定出棉花中角鲨烯合成关键基因 _GhSQS1_。进一步研究发现，过表达该基因伴随油菜素内酯相关代谢及信号通路变化，且显著提高棉花叶片角鲨烯含量，其中代表性株系OE2达到989.1 mg\u002Fkg干重，较野生型提高约70%，同时表现出叶片增大、根系发育改善、纤维伸长和种子增大等性状。在模拟干旱和碱胁迫条件下，过表达该基因的植株表现出较强的耐受能力，并伴随抗氧化能力增强和膜脂过氧化程度降低。此外，异源表达真菌来源角鲨烯合酶也获得了类似的促生长表型，表明增强角鲨烯合成有助于改善棉花发育。研究结果表明，增强角鲨烯生物合成与棉花生长发育及逆境适应能力改善之间的联系，为通过代谢工程协同改良作物性状与提高功能性天然产物积累提供了新思路，也为棉花副产物高值化利用提供了研究基础。\n\n该研究得到中国农业科学院青年创新专项、河南省自然科学基金、新疆维吾尔自治区重点研发计划、国家自然科学基金、国家现代农业产业技术体系等项目支持。中棉所徐雅梦、张志甜、刘乐和贾舒元为论文共同第一作者，李付广研究员和杨作仁研究员为共同通讯作者。\n\n原文链接：https:\u002F\u002Fdoi.org\u002F10.1093\u002Fjxb\u002Ferag424\n\n![Image
