Secondary Growth and Exodermal Barriers Shape Local Root Hydraulics: Modeling Insights in Tomato
Abstract. Root water uptake efficiency depends on root system architecture and anatomical features of individual root segments. Beyond cell wall, membrane,

dimerization defects affect adhesion through largely separate pathways. (A-G)
Representative max intensity Z-projections of confocal stacks from 4-days-old darkgrown hypocotyl stained with propidium iodide from Col-0 (A), mur1-2 (B), qua2-1 (C),
mur1-2 qua2-1 (D), esmd1-1 (E), mur1-2 esmd1-1 (F) and qua2-1 esmd1-1 (G). (H)
Schematic representation of Boron-Rhamnogalacturonan-II (RG-II) dimers and
Calcium-Homogalacturonan (HG) “egg-box” crosslinking domains along the HG
backbone. (I) Quantification of the relative ruthenium red staining intensity (see
representative images and length quantification in figure S3). Boxplots summarize
three biological replicates, as represented by dots of different colors, and letters
describe the statistically significant differences between populations determined by
one-way ANOVA followed by Tukey’s HSD test (P < 0.05).[Scale bars, 30µm in images
