盛夏时节，北京市海淀区中关村南大街12号院农科东大道。从中国农业科学院东门进入，远远就能看到 一栋现代化的白色建筑。正面墙上，由"禾"与"重"组成的篆刻字"种"格外醒目。 这里是国家农作物种质资源库，也是守护农作物种质资源的"诺亚方舟"—— 如同有了一些特定野生稻基因的留存，人类才能成功创制出超级杂交稻，很多种质资源蕴藏着潜在可利 用基因，是人类的宝贵财富。但由于气候变化、人类活动等，很多种质资源在野外面临着灭绝危机。将 这些种质资源收集起来并进行科学保存，能延长它们的寿命，并在不断进步的科技加持下，打开未来无 限可能的空间。 2021年7月9日，中央全面深化改革委员会第二十次会议审议通过《种业振兴行动方案》，种质资源保护 是其中的重要内容。 当前种业振兴行动已迈入第5个年头。作为种业振兴的基础工作，我国新保存了哪些重要种质资源？应 用了哪些新技术，种质资源保存效果如何？近日，记者来到国家农作物种质资源库，一探究竟。 走进5层楼高的种质库，一间间宽敞明亮的库房里整齐摆放着已经贴上二维码、条形码的种子瓶，试管 苗容器，液氮罐。 "在这里，每个种类的种子都有自己的身份信息。"中国农业科学院工作人员张金梅介绍说，我 ...

原标题：对抗高温，水稻有"秘密武器" 记者5月12日获悉，华中农业大学作物遗传改良全国重点实验室教授李一博课题组首次揭示了水稻 对抗高温的"秘密武器"——基因QT12。相关研究成果日前发表在国际期刊《细胞》上。 多国农业模型分析表明，全球平均气温每升高1摄氏度，将直接导致水稻产量减少3.2%。极端高温 天气频发，对水稻等主要粮食作物的产量和品质构成严峻挑战。 长江流域是我国第一大水稻主产区。2024年，在长江流域极端高温天气下，科研团队开展了大规模 田间试验。结果显示，基因QT12在高温环境下展现出很强的耐热性。与野生型相比，CRISPR编辑的 QT12基因株系在武汉、杭州和长沙种植的水稻小区产量分别提升了92.5%、64.1%和54.7%。 此外，基因QT12导入到杂交稻品种"华占"中，能显著提高其结实率、单株产量和稻米品质，导致 在武汉、杭州和长沙种植的水稻小区产量分别增加了49.1%、77.9%和31.2%，进一步验证了其在高温环 境下的育种实力。 据悉，科研团队已与多家国内龙头企业达成转化开发意向协议，相关成果将在育种实践中发挥重要 作用。（记者吴纯新 通讯员蒋朝常） 李一博课题组发现，当高温来袭，基 ...

Core Insights - A key gene named QT12 has been discovered by a research team led by Professor Li Yibo from Huazhong Agricultural University, which enables rice to withstand high temperatures, addressing a significant threat to food security due to climate change [1][2] - The research findings were published in the international journal "Cell" on April 30, 2023, highlighting the importance of developing heat-resistant rice varieties for stable yields in high-temperature environments [1] Group 1 - The research team conducted extensive genetic analysis and identified the QT12 gene, which interacts with the protein complex NF-Y to create a molecular "firewall" that protects rice grains from high temperatures [1] - The study demonstrated that QT12 helps maintain the stability of protein and starch synthesis during high-temperature conditions, ensuring the quality and yield of rice [1] Group 2 - In field trials conducted in the Yangtze River basin under high-temperature conditions, the introduction of QT12 into the hybrid rice variety "Huazhan" significantly increased its seed setting rate, single-plant yield, and rice quality, with yield increases of 49.1% in Wuhan, 77.9% in Hangzhou, and 31.2% in Changsha [2] - The research team has reached agreements with several domestic companies for the transformation and development of these research results, aiming to accelerate their application in breeding practices [2]
