Mobile transcription factors play many roles in plant development. Here, we compare the use of mobile transcription factors as signals with some canonical signal transduction processes in prokaryotes and eukaryotes. After an initial survey, we focus on the SHORT-ROOT pathway in Arabidopsis roots to show that, despite the simplicity of the concept of mobile transcription factor signalling, many lines of evidence reveal a surprising complexity in control mechanisms linked to this process. We argue that these controls bestow precision, robustness, and versatility on mobile transcription factor signalling.
移动转录因子在植物发育中发挥着多种作用。在这里，我们将移动转录因子作为信号的用途与原核生物和真核生物中的一些经典信号转导过程进行了比较。在初步调查之后，我们将重点放在拟南芥根中的SHORT-ROOT 途径上，以表明尽管移动转录因子信号的概念很简单，但许多证据揭示了与该过程相关的控制机制具有惊人的复杂性。我们认为，这些控制机制使移动转录因子信号具有精确性、鲁棒性和多功能性。
