Fig. 3: Vertex-based model of growth-derived water fluxes.
From: Water fluxes pattern growth and identity in shoot meristems
A–D Multicellular model at regular intervals \({{\boldsymbol{\Delta }}}{{\boldsymbol{T}}}={{\boldsymbol{4.3}}}\,{{\boldsymbol{h}}}\), from the initial condition to the final stage: cells in the center deform elastically but cannot grow, they accumulate water from an external source and pressure; conversely, wall growth relaxes tension in cells in L1–L3; thanks to their lower pressure, they attract water from the center. A To mimic organ outgrowth, E is reduced (E x 0.25) in a subgroup of L1L2 cells (black dots) at time \({{\boldsymbol{T}}}={{\boldsymbol{0}}}\). A–D Maps of elastic deformation, hydrostatic pressure, fluxes, and relative growth rate; the boundary cells are indicated by red arrows in (C).
