Figure 6. PID is required for relocalization of PIN1 but not microtubules after ablation.

Visualization of PIN1-GFP (red) and TagRFP-MAP4 (green) before (A and B) and after (C and D) laser-induced cell ablation (asterisk) in a pid mutant background. After ablation microtubules reorient around the wound similarly to wild-type. In contrast, PIN1 repolarization in the pid mutant is significantly reduced and remains uncorrelated with microtubule orientations (arrows). Scale bar: 5 µm.
