Popis:	The formation of vein patterns in leaves has captivated biologists, mathematicians, and philosophers. In leaf development, files of vein-forming procambial cells emerge from within a seemingly homogeneous subepidermal tissue through the selection of anatomically inconspicuous preprocambial cells. Although the molecular details underlying the orderly formation of veins in the leaf remain elusive, gradually restricted transport paths of the plant signaling molecule auxin have long been implicated in defining sites of vein differentiation. Several recent advances converge to more precisely define the role of auxin flow at successive stages of vascular development. The picture that emerges is that of vein formation as a self-organizing, reiterative, auxin-transport-dependent process.
