Angiosperms are the most successful group of land plants. This success is mainly due to the gynoecium, the innermost whorl of the flower. In Arabidopsis, the gynoecium is a syncarpic structure formed by two congenitally fused carpels. At the fusion edges of the carpels, the carpel margin meristem forms. This quasi-meristem is important for medial-tissue development, including the ovules. After the double fertilization, both the seeds and fruit begin to develop. Due to the importance of seeds and fruits as major food sources worldwide, it has been an important task for the scientific community to study gynoecium development. In this review, we present the most recent advances in Arabidopsis gynoecium patterning, as well as some questions that remain unanswered.
被子植物是最成功的陆生植物群体。这种成功主要归因于雌蕊，即花的最内轮。在拟南芥中，雌蕊是由两个先天融合的心皮形成的合生结构。在心皮的融合边缘，心皮边缘分生组织形成。这个拟分生组织对于包括胚珠在内的中组织发育很重要。双受精后，种子和果实开始发育。由于种子和果实作为全球主要食物来源的重要性，科学界研究雌蕊发育一直是一项重要任务。在这篇综述中，我们介绍了拟南芥雌蕊模式形成的最新进展，以及一些尚未解答的问题。
