Vascular tissues in plants are crucial to provide physical support and to transport water, sugars and hormones and other small signalling molecules throughout the plant. Recent genetic and molecular studies have identified interconnections among some of the major signalling networks that regulate plant vascular development. Using Arabidopsis thaliana as a model system, these studies enable the description of vascular development from the earliest tissue specification events during embryogenesis to the differentiation of phloem and xylem tissues. Moreover, we propose a model for how oriented cell divisions give rise to a three-dimensional vascular bundle within the root meristem.
植物的血管组织对于提供物理支撑和在植物体内运输水、糖和激素以及其他小的信号分子至关重要。最近的遗传和分子研究已经确定了一些主要信号网络之间的相互联系，这些网络调节植物血管发育。使用拟南芥作为模型系统，这些研究能够描述从胚胎发生过程中最早的组织特化事件到韧皮部和木质部组织的分化的血管发育。此外，我们提出了一个模型，说明定向细胞分裂如何在根分生组织内产生三维血管束。
