FIGURE 1.
Repressor ARFs inhibit root hair growth. (A) Root hair phenotypes of control (Cont; ProE7:YFP) and root hair-specific ARF-overexpressing lines (ProE7:ARFs) in the wild-type background. Bar is 100 μm for all. (B) Root hair length of control and ARF-overexpressing lines. Error bars indicate ± SE (n = 163–1,482 root hairs from 12 to 78 plants from 4 to 6 independent lines for transformants). Statistically significant differences are denoted by different letters (one-way ANOVA with Tukey’s unequal N-HSD post hoc test, P < 0.05).
