为了让植物胚胎从单个受精卵细胞生长到复杂的多细胞结构，它必须经历高度有序的细胞分裂序列，在这个过程中，新出现的组织被构思并最终分化。在维管植物中，维管组织位于根和茎的深处，在那里它们提供了器官之间水分和养分运输的主要机制。根部维管组织的规格为研究组织模式提供了一个优雅的系统。以前已经证明，两种植物激素相互交叉调节对方的活动和运输，以控制维管模式。然而，在这一期的第636页上，de Rybelet等人通过调节这些激素的局部合成，确定了这些激素之间的新的相互作用，使得这些激素相互作用共同协调细胞分裂和组织模式的过程，以指定拟南芥中典型的血管模式。
For a plant embryo to grow from a single fertilized egg cell to a complex multicellular structure, it must undergo a highly ordered sequence of cell divisions, during which the emerging tissues are patterned and ultimately differentiate. In vascular plants, the vascular tissues lie deep within roots and shoots, where they provide the main mechanism for transporting water and nutrients between organs. The specification of root vascular tissues provides an elegant system to investigate tissue patterning. It had previously been shown that two plant hormones cross regulate each other's activity and transport to control vascular patterning . However, on page 636 of this issue, De Rybelet al.identify a new interaction between these hormones through the regulation of their local synthesis, such that collectively these hormonal interactions coordinate the processes of both cell division and tissue patterning to specify the stereotypical vascular pattern inArabidopsisembryos.
