摘要

ZmMADS1启动子的一个178 bp拷贝数变异抑制了ZmMADS1的表达并导致开花延迟，这是玉米在高海拔地区传播过程中的选择目标。ZmMADS1通过直接激活ZmMADS69和ZCN8的表达，同时抑制ZmRap2.7，通过自主途径促进玉米开花。

A copy number variation in the ZmMADS1 promoter enhances maize adaptation to high altitudes

A 178-bp copy number variation in the ZmMADS1 promoter represses ZmMADS1 expression and results in delayed flowering, which has been a target of selection during maize spread into higher altitudes. ZmMADS1 promotes maize flowering via the autonomous pathway by directly activating the expression of ZmMADS69 and ZCN8, while repressing ZmRap2.7.
