A key question about the development of multicellular organisms is how they precisely control the complex pattern formation during their growth. For plants to grow for many years, a tight balance between pluripotent dividing cells and cells undergoing differentiation should be maintained within stem cell populations. In this process, cell-cell communication plays a central role by creating positional information for proper cell type patterning. Cell-type specific gene regulatory networks govern differentiation of cells into particular cell types. In this review, we will provide a comprehensive overview of emerging key signaling and regulatory programs in the stem cell population that direct morphogenesis of plant vascular tissues.
关于多细胞生物发育的一个关键问题是，它们如何在生长过程中精确控制复杂的模式形成。对于能够多年生长的植物来说，干细胞群体中多能分裂细胞和正在分化的细胞之间应保持紧密的平衡。在这个过程中，细胞间通讯通过为正确的细胞类型模式创建位置信息发挥核心作用。细胞类型特异性基因调控网络控制细胞分化为特定的细胞类型。在这篇综述中，我们将全面概述干细胞群体中新兴的关键信号传导和调控程序，这些程序指导植物维管组织的形态发生。
