Cell-size patterning occurs as a basipetal wave simultaneously on the adaxial and abaxial sides of the leaf. Cell area heat maps in µm2 of leaf 1 or 2 at different stages of development on the abaxial side (Top Row) and on the adaxial side (Bottom Row) of the same leaf at 5, 6, 7, 8, and 9 dpg (half leaf). Unsegmented regions on adaxial leaves correspond to trichomes, which were not considered in this analysis. Each stage is associated with a distinct heat map color range. Scale bars represent 50 µm at 5 and 6 dpg, and 100 µm at 7, 8, and 9 dpg.
