Topology across the leaf, generated through divisions. (A-D) The Arabidopsis spch leaf epidermis at an early time point (A,B), 175.17 hours after stratification (HAS), and a later time point (C,D), 286.50 HAS. (B,D) Heat maps of the neighbour number of each cell for A and C, respectively. (E-H) Divisions influence local topology. Cell before dividing (E), at 220.42 HAS, with neighbour numbers quantified in F. After division, 12.2 h later, the neighbourhood of the cell alters (G), as quantified in H. Scale bars: 20 µm in B; 100 µm in D; 2 µm in E,G.
