Quantitative analysis of root hair formation in response to phosphate starvation in wild type and mutant genotypes. Two independent experiments are shown in which root hair number is compared in N- and H files between at least 10 wild type and mutant seedlings under normal conditions and under phosphate starvation conditions. RHC zone indicates the region of root hair analysis. Red stars indicate a significant difference between Pi+ and Pi– conditions at ^∗p < 0.5, ^∗∗p < 0.01, ^∗∗∗p < 0.001 (Wilcoxon test). Black stars indicate a significant difference between wild type and mutants at ^∗p < 0.5, ^∗∗p < 0.01, ^∗∗∗p < 0.001 (Wilcoxon test).
