摘　　要：在进化过程中,植物演化出不同的有效繁殖策略。其中,雌蕊是被子植物成功繁殖的关键。拟南芥雌蕊是通过多极性系统建立起来的一个复杂的组织结构,它的发育需要通过极性建立组织特异性。拟南芥的雌蕊由两个先天融合的心皮形成,基因调控网络(gene regulatory networks, GRNS)控制和引导雌蕊的发育和分化。生长素-细胞分裂素激素途径作为GRNs的调控部分在雌蕊早期发育中起到重要作用。本综述介绍了最近几年拟南芥雌蕊发育早期相关基因,主要介绍了沿极性轴排列的雌蕊发育GRNs,同时介绍了内部和外部因素修饰GRNs的研究进展。In the process of evolution, plants have evolved different effective reproductive strategies. Gynoecium is the key to the successful reproduction of angiosperms. The gynoecium of Arabidopsis thaliana is a complex tissue structure established by multipolar system, and its development needs to establish tissue specificity through polarity. The gynoecium of Arabidopsis thaliana is formed by two congenital fused carpels. Gene regulatory networks(GRNs) control and guide gynoecium development and differentiation. As a regulatory part of GRNs, auxin cytokinin pathway plays an important role in early gynoecium development. This review summarizes the genes related to early gynoecium development in Arabidopsis thaliana in recent years, mainly introduces the GRNs arranged along the polar axis, and introduces the research progress of GRNs modified by internal and external factors.
