细胞分裂和细胞命运的特化决定了维管的模式。一组转录因子决定了维管圆柱的大小。生长素,细胞分裂素和III类HD-ZIP蛋白的水平决定了细胞的命运。最近的研究揭示了这些过程如何相互作用来控制模式。拟南芥根为理解模式化过程和细胞命运特化提供了一个很好的模型。维管图案化代表了一个特别有趣的过程,因为必须产生新的位置信息,以将近似径向对称的根极转化为具有单个木质部轴的双对称结构。这个过程需要胚胎组织的生长以及随后的图案化。近年来,研究者们发现了一系列调控细胞分裂以控制血管组织生长的转录因子。生长素和细胞分裂素这两种激素信号的空间调节与其他转录因子联合收割机结合形成木质部轴。我们现在正目睹这些激素之间越来越复杂的相互作用的发现,这些相互作用可以通过使用数学模型来解释。
HighlightsCell division and cell fate specification determine vascular pattern.A group of transcription factors specify the size of the vascular cylinder.Auxin, cytokinin and class III HD-ZIP protein levels determine cell fate.Recent research is uncovering how these processes interact to control patterning.The Arabidopsis root has provided an excellent model for understanding patterning processes and cell fate specification. Vascular patterning represents an especially interesting process, as new positional information must be generated to transform an approximately radially symmetric root pole into a bisymmetric structure with a single xylem axis. This process requires both growth of the embryonic tissue alongside the subsequent patterning. Recently researchers have identified a series of transcription factors that modulate cell divisions to control vascular tissues growth. Spatial regulation in the signalling of two hormones, auxin and cytokinin, combine with other transcription factors to pattern the xylem axis. We are now witnessing the discovery of increasingly complex interactions between these hormones that can be interpreted through the use of mathematical models.
