Influence of cortex anatomy (number of cortex layers and cell size) on k_r for simulated monocot anatomies. A, Overview of k_r values across the parametric space where endodermal Casparian strip is the only apoplastic barrier. The colored dashed lines represent the cortex width isoline (mm), and the dotted lines are a visual representation of the fixed parameters for the two subplots (C and D). B, Evolution of the relative k_r as the cortex width increases. C, Evolution of the relative k_r as the cortex cell diameter increases for the number of cortex layers fixed to six. D, Evolution of the relative k_r as the number of cortex layers increases for a cortex cell diameter set to 0.03 mm. B to d, The colors represent different levels of hydrophobic barrier development. 1: Endodermal Casparian strip (blue); 2: Endodermal suberization (red); 3: Endodermis full suberization and exodermal Casparian strip (green).
