Abstract In plants, the vascular network enables the transport of water, nutrients and metabolites. The vascular network formed in leaves is a striking example of tissue patterning, and leaf venation is a defining leaf feature. During patterning, veins arise from aligned, elongated procambial cells derived from undifferentiated ground meristem cells. The mechanisms behind procambial strand formation involving cell selection, polarization, alignment, elongation and division have remained elusive.
