Particle-based model shows complex rearrangement of tissue mechanical properties are needed for roots to grow in hard soil

The particle model.

(A) The interaction between cells is described through the kernel function (blue) associated with the particle (see Method A in S1 Text), which is a function that decreases with the distance from the particle center with the smoothing length. . It can be used to recover various field quantities, here the wall potential which indicates the likeliness of the position of the cell wall. (B) Ellipsoids define the size and shape of the cell. An ellipsoid is defined by its principal axes (here long in green, short in red) and used to generate the wall potential (background color, yellow being the most probable location of a wall and orange being the ridge). (C) The cell division occurs along the longest axis and split the mother cell into equally sized daughter cells.
