Actin perturbation disrupts the alignment between the PPB and the division site.
Time-lapse analysis of dividing trichoblast in root expressing the microtubule reporter IQD8-GFP (green) and the plasma membrane marker 2xmCh2xPHFAPP1 (magenta), after 2h-LatB.

PPB-defective mutants (ton1a, trm678) show tilted but laterally confined divisions, suggesting safeguards prevent apicobasal division
F-actin (cyan) accumulates at apicobasal cell faces during division, supporting a potential instructive role for F-actin in orienting the division plane
