The body of higher plants is usually pervaded by the (pro)cambium, a reticulate system of meristematic cells harboring the potential for producing vascular tissues at critical times and places. The (pro)cambium thereby provides the basis for the differential modulation of long-distance transport capacities and plant body stability. Distinct regulatory networks responsible for the initiation and proliferation of (pro)cambium cells have been identified. However, although a tight interaction between these networks can be expected, connections have been established only sporadically. Here we highlight recent discoveries of how (pro)cambium development is regulated and discuss possible interfaces between networks regulating two processes: (pro)cambium formation and cambium proliferation.
高等植物的体内通常布满了（原）形成层，这是一种由分生细胞构成的网状系统，在关键的时间和地点具有产生维管组织的潜力。（原）形成层因此为长距离运输能力的差异调节和植物体稳定性提供了基础。负责（原）形成层细胞起始和增殖的不同调控网络已被识别。然而，尽管可以预期这些网络之间会有紧密的相互作用，但目前仅偶尔建立起了联系。在这里，我们重点介绍了有关（原）形成层发育如何受到调控的最新发现，并讨论了调控两个过程的网络之间可能存在的界面：（原）形成层的形成和形成层的增殖。
