AtZP1 Functions in the Same Genetic Pathway as RHD6, RSL4, and RSL2.

(A) to (C) Relative expression levels of RHD6 (A), RSL4 (B), and RSL2 (C) in different lines. Three biological replicates were performed. Error bars indicate sd (n = 3). Statistical significance was determined by one-way ANOVA, Duncan’s multiple range test. Significant differences at P < 0.05 are represented by different letters (a to d) above the bars.

(D) Root hair phenotype of the 5-d-old wild-type (Cont) plants; AtZP1 overexpression lines (L2 and L7); and RHD6, RSL4, and RSL2 overexpression lines in the L2 and L7 background. Bar = 500 μm.
