记者12月1日从南京农业大学获悉，该校植物保护学院教授董莎萌课题组联合中国农业科学院深圳农业 基因组研究所研究员黄三文团队构建出目前规模最大的马铃薯抗病基因资源库，成功克隆了三个新型抗 晚疫病基因，并提出了基因"插件式"抗病育种新策略。相关成果近日刊发在国际学术期刊《自然》上。 马铃薯晚疫病是严重威胁粮食安全的重大病害，每年造成近百亿美元的经济损失。由于晚疫病病原菌致 病疫霉菌变异迅速，现有马铃薯抗病基因已对其逐渐失效，因此亟待挖掘新型抗性基因资源，革新抗病 育种策略。 "基于泛抗病基因组资源，我们成功克隆了三个新型抗晚疫病基因。这些抗病新基因为通过常规育种手 段精准设计马铃薯晚疫病抗性提供了资源支撑。"论文第一作者、中国农业科学院深圳农业基因组研究 所副研究员王路遥说。更具突破性的是，团队提出"结构域插件"育种策略：将野生马铃薯中发现的抗晚 疫病基因的功能结构域"嫁接"到已失效的晚疫病抗病基因R1的末端，使R1可同时识别病原物分泌蛋白 AVR1与AVRbrk1，这成功拓展了R1基因的抗病谱。 "这种'即插即用'的基因设计思路，为快速创制广谱抗病品种提供了全新路径。"董莎萌认为，此项研究 不仅构建了高质量的抗 ...
