A Theoretical Model of Jigsaw-Puzzle Pattern Formation by Plant Leaf Epidermal Cells

Characteristics of cell wall three-way junctions.
(a) Time-lapse observation of a three-way junction using the membrane marker GFP-PIP2a. The angles were mostly 120°. Scale bar = 10 μm. (b) The relationship between cell size and the degrees of three-way junctions 7 days after sowing. Larger, more developed cells were more likely to have angles closer to 120°. RMSD, root-mean-square deviation. See also S3 Fig for data from samples 2 and 4 days after sowing. (c) Snapshots of the numerical simulation of the model at a three-way junction. The numerical simulation shows that the angles of a three-way junction gradually approach 120°.
