全球首个绿豆泛基因组,鉴定关键基因,重大科研突破,但发表于2026年8月,时效性差。

摘要

中国农业科学院作物科学研究所特色农作物优异种质资源发掘与创新利用创新团队联合国内外单位,构建全球首个高质量绿豆图泛基因组。从全球580份绿豆种质资源中筛选出11份代表性材料,组装构建首个绿豆图泛基因组,鉴定出调控黄酮代谢合成、增强绿豆抵抗害虫豆象的关键基因。前者通过启动子插入及编码区突变调控黄酮积累,与荞麦黄酮合成调控机制一致;后者启动子缺失变异增强基因表达、抑制关键抗虫降解酶活性、维持种皮结构完整。成果发表在《自然·遗传学(Nature Genetics)》。注:本成果基于11份代表性核心种质,实际育种应用仍需更广泛的验证。

Pangenome-guided breeding restores high-altitude adaptation and improves yield in Tartary buckwheat

中国农业科学院作物科学研究所周美亮研究员、兰州大学刘建全教授、中国农业科学院刘旭院士等团队合作,在国际顶尖期刊Cell发表苦荞泛基因组研究。研究构建鞑靼荞麦(苦荞)的泛基因组,鉴定到赋予高海拔适应性的野生特有基因FtRNH以及调控种子大小的FtPLATZ基因结构变异。通过整合这些优良等位基因,培育出具有更强高海拔适应性和更高田间产量的荞麦品系,在高海拔条件下较对照品种增产约25%。该研究为弥补高海拔作物育种空白、提高喜马拉雅地区作物产量提供科学依据。
