| Abstract: | When all of the procambial strands are identified and followed in serial cross sections of shoot tips of Zea mays, a pattern to the initiation of the vascular system emerges. A primary thickening meristem, which is near the periphery of each disk of insertion bearing a leaf primordium, generates a succession of waves of isolated procambia. Differentiation of the ground meristem between these isolated procambial sites (dot-to-dot growth) advances a resulting sympodium proximally toward a leaf primordium and distally in the axis. Sympodia are not destined to become particular leaf traces; competition among the adjacent procambial sites determines the course of a sympodium. A sympodium becomes recognized as a particular leaf trace when a dot-to-dot interconnection (capturing) occurs between a procambial site in the leaf primordium and a site in a recent wave of a disk of insertion. Those procambia that do not contribute to a leaf trace because they persist in isolation will eventually contribute to the horizontal component of the nodal plexus. Keywords: development, disk of insertion, leaf trace, nodal plexus, primary thickening meristem, procambium, vascular system, Zea. [ABSTRACT FROM AUTHOR] |
