A fascinating feature of plant growth and development is that plants initiate organs continually throughout their lifespan. The ability to do this relies on specialized groups of pluripotent stem cells termed meristems, which allow for the elaboration of the shoot, root, and vascular systems. We now have a deep understanding of the genetic networks that control meristem initiation and stem cell maintenance, including the roles of receptors and their ligands, transcription factors, and integrated hormonal and chromatin control. This review describes these networks and discusses how this knowledge is being applied to improve crop productivity by increasing fruit size and seed number.

植物生长和发育的一个典型特色在植物的整个一生中会持续不断的发生器官起始。植物的这种能力依赖于一群特异化的多能性干细胞，叫做分生组织，使得植物能够不断分化出新的茎、根以及维管系统。目前，我们对于控制分生组织起始以及干细胞维持的遗传机制已经有了很深入的了解，包括受体以及配基、转录因子、各种植物激素以及染色质控制在该过程中的作用。本文的综述了这些调控因子的网络，讨论了这些知识如何可以应用到作物产量提升方面，增加果实的大小和种子的数量。
