Evolution has provided at least two particularly successful independent solutions to the problems of multicellularity - animals and higher plants. An obvious requirement for successful multicellularity is communication between different parts of the organism, both locally, for example between neighbouring cells, and over very long distances. Recent advances in understanding hormone signalling networks in plants are beginning to reveal how co-ordination of activity across the whole plant body can be achieved despite the lack of a control centre, typical of animal systems. Of particular importance in this distributed regulatory approach are the self-organising properties of the transport system for the plant hormone auxin. This review examines the integrative role of the auxin transport network in co-ordinating plant growth and development.
进化为多细胞生物提供了至少两种特别成功的独立解决方案——动物和高等植物。成功的多细胞生物的一个明显要求是生物体不同部分之间的通信，包括局部的，例如相邻细胞之间，以及非常长距离的通信。最近在理解植物激素信号网络方面的进展开始揭示，尽管缺乏典型的动物系统的控制中心，整个植物体的活动如何可以实现协调。在这种分布式调节方法中，特别重要的是植物激素生长素的运输系统的自组织特性。这篇综述探讨了生长素运输网络在协调植物生长和发育中的整合作用。
