Root hair morphology and functioning in Atrgtb mutants. (A) Aberrations in root hair morphology; scale bar=30 μm. (B) Frequency of abnormal root hairs; bars represent the mean ±SE. Statistical significance was analysed by Mann–Whitney test, **P<0.01, ***P<0.001. (C) Time course of FM 1-43 styryl dye uptake and recycling in root hairs, confocal microscopy. Z-stacks of ~20 images from each root hair are shown. Scale bar=30 μm. Note large dye aggregates in mutant cells (arrowhead). Representative images are shown.
