多细胞生物依靠器官的活动发育成特定的大小和形状，并形成特定的组织。最复杂的植物结构之一是雌性生殖器官雌蕊，它必须整合一系列发育线索以确保高效繁殖。在这里，我们回顾了最近在基因网络和激素活动方面的发现，这些基因网络和激素活动需要(1)控制细胞分裂，(2)雌蕊沿极性轴排列，(3)指定器官形状和种子传播。将被子植物与其他植物器官进行比较，以了解从叶片形成进化而来的发育程序如何被招募和修改，从而创造出一种生殖机制，使被子植物能够统治世界。
Multicellular organisms rely on the activity of organs that develop to a specific size and shape and are patterned into particular tissues. One of the most complicated plant structures is the female reproductive organ, the gynoecium, which must integrate a range of developmental cues to ensure efficient reproduction. Here we review recent discoveries on gene networks and hormonal activities that are required to (1) control cell division, (2) pattern the gynoecium along polarity axes and (3) specify organ shape and seed dispersal. Comparisons are made to other plant organs to understand how a developmental programme, which is evolutionarily derived from the formation of leaves, has been recruited and modified to create a reproductive machinery that has allowed angiosperms to dominate the world.
