农作物驯化推动了农业文明的出现和繁荣, 是人类历史上的重大事件。玉米(Zea mays)作为全球范围内的重要粮食作物, 其驯化起源一直备受生物学和历史学界的关注。之前, 现代玉米起源自小颖大刍草亚种(Z. mays subsp. parviglumis)的观点一直占主流地位。近期, 严建兵与其合作团队系统收集并梳理了玉米各种类型野生种和栽培种资源, 综合运用基因组学、群体遗传学和数量遗传学方法及考古学成果, 发现现代玉米也存在墨西哥高原亚种(Z. mays subsp. mexicana)的杂交渐渗, 并影响了诸多农艺性状, 进而提出现代玉米起源的新模型。

The domestication of crops was a significant event in human history, which led to the emergence and prosperity of agricultural civilization. Maize is an important global food crop, and its domestication origin has long attracted the attention of both the biological and historical communities. The mainstream view in the past was that modern maize originated from the parviglumis type of teosinte. Recently, Yan Jianbing and his collaborators systematically collected and sorted various types of wild and cultivated maize resources, and comprehensively applied genomics, population genetics, and quantitative genetics methods, along with the use of archaeological findings. They found that modern maize also has the gene introgression of the mexicana type of teosinte, which has influenced many agronomic traits. A new model for the origin of modern maize has been proposed based on these findings.
