Comparison of wild-type, bri^TRIPLE and bri^T-RESCUE root meristems.

(A) Transverse sections of representative 8-day-old primary root meristems of the three genotypes. Note the comparatively disorganized morphology of bri^TRIPLE meristems.

(B–D) Scatterplots of cell length (B), width (C), and volume (D) for the root meristem cell types analyzed through the PlantSeg-MorphoGraphX-3DCellAtlas pipeline. Models were fitted to the measurements for each genotype using a general additive model with a shrinking cubic regression spline interpolation; gray areas indicate the SE. Variation within roots of the same genotype is generally high, making comparisons of the cellular properties difficult.
