Formation of leaf vascular pattern requires regulation of a number of cellular processes, including cell proliferation. To assess the role of cell proliferation during vein order formation, leaf development in genetic lines exhibiting aberrant cell proliferation patterns due to altered expression patterns of ANT and ICK1 genes was analyzed. Modification of cell proliferation patterns alters the number of higher order veins and the number of minor tertiary veins remodeled as intersecondary veins in Arabidopsis rosette leaves. Minor vein complexity, as indicated by branch point and freely ending veinlet number, is highly correlated with a decrease or increase in cell proliferation. Observations of procambial strand formation in modified cell proliferation pattern lines showed that vein pattern is specified early in leaf development and that formation of freely ending veinlets is temporally correlated with the expansion of ground meristem when cell proliferation is terminated prematurely. Taken together, our observations indicate that: (1) genes that modulate cell proliferation play a key role in regulating the meristematic competence of ground meristem cells to form procambium and vein pattern during leaf development, and (2) ANT is a crucial part of this regulation.
