Figure 4

Plants lacking complex N-glycans display an altered auxin response. (A) root hair density, (B) root hair length, and (C) distance between first general and first partially elongated root hair of wild-type (Col-0, black boxes) and gntI plants (gray boxes) cultivated for 8 days on plates supplemented with the indicated NAA concentrations. Letters indicate significant differences between groups [p ≤ 0.05; (A,C) two-way ANOVA with Tukey post hoc test; (B) Kruskal-Wallis test, FDR corrected via Benjamini-Hochberg]. (D) Pictures of representative root tips. Black arrows indicate the first general root hair while white arrows point to the first partially elongated root hair. Scale bars: 500 μm.
