Aeo1 mutant related to polar development of maize flower organs and application thereof

The invention discloses an aeo1 mutant related to polar development of corn flower organs, a construction method and application thereof, and belongs to the field of corn fundamental research, a gene for coding the aeo1 mutant can regulate and control the polar development of the plant flower organs, enables the phenotype of a cluster base to be subjected to polar transformation, can regulate and control extra flowers in plant clusters not to degenerate, and has a good application prospect. Therefore, more grains are generated, and the plant yield is increased. The method not only can provide theoretical guidance for analyzing polar development of maize flower organs, but also creates conditions for genetic improvement of maize. 本发明公开了一种与玉米花器官极性发育相关的aeo1突变体、构建方法及其应用，属于玉米基础研究领域，本发明公开的编码aeo1突变体的基因可调控植物花器官极性发育，使果穗基座表型发生极性转变，并且能够调控植物果穗中额外花不退化，进一步发育，从而产生更多籽粒，增加植物产量。本发明不仅能为解析玉米花器官极性发育提供理论指导，也为玉米的遗传改良创造了条件。
