Changes in the tensile stress pattern shift the orientation of stomata divisions (IMAGE)
Caption
Changes in the tensile stress pattern shift the orientation of stomata divisions: Figure G–H: Computational modelling of differential growth and predicted stress orientation in the cotyledon. (G) Distribution of growth rates applied to the cotyledon simulation, based on the cotyledon shown in panel D and two additional biological replicates. Simulated growth rates differ between the abaxial and adaxial surfaces, with higher growth rates on the adaxial side. Colours indicate relative growth rate across the cellular mesh. (H) Predicted orientation of differential growth-derived tensile stress on the abaxial and adaxial cotyledon surfaces. Solid lines indicate the principal direction of tensile stress and dashed lines indicate the minimal tensile stress direction. Colours represent stress anisotropy, with higher anisotropy shown in yellow and lower anisotropy in purple. Scale bar: 50 μm. Modelling by Euan Smithers.
