Schematics of Expression Patterns of Regulatory Molecules in Young Leaves with Different Allometries.

Distribution of the patterning molecules like miR396, HISTONE H4, and miR396-targeted GRFs are schematically shown along the proximo-distal axis of young leaves and compared with the pattern of cell proliferation/differentiation. Expression of miR396 shows a strong correlation with the pattern of cellular maturation in leaves with different growth allometries. Expression of HISTONE H4 and miR396-targeted GRFs, by contrast, closely matches with the domains of cell proliferation.
