The regulation of plant growth responds to many stimuli. These responses allow environmental adaptation, thereby increasing fitness. In many cases, the relay of information about a plant's environment is through plant hormones. These messengers integrate environmental information into developmental pathways to determine plant shape. This review will use, as an example, auxin in the root of Arabidopsis thaliana to illustrate the complex nature of hormonal signal processing and transduction. It will then make the case that the application of a systems-biology approach is necessary, if the relationship between a plant's environment and its growth/developmental responses is to be properly understood.
植物生长的调控响应多种刺激。这些响应允许环境适应，从而提高适应性。在许多情况下，关于植物环境的信息传递是通过植物激素实现的。这些信号将环境信息整合到发育途径中，以确定植物的形状。本文将以拟南芥根中的生长素为例，来说明激素信号处理和转导的复杂性质。然后，本文将提出，如果要正确理解植物环境与其生长/发育响应之间的关系，那么应用系统生物学方法是必要的。
