Targets of ROOT HAIR DEFECTIVE SIX‐LIKE4 (RSL4) regulation encode proteins involved in cell signalling, cell wall modification and secretion that are required root hair growth. (a) Seven‐day‐old Arabidopsis thaliana wild‐type (Col‐0 roots), suppressor of actin 1‐2 (sac1‐2), peroxidase7‐1 (prx7‐1), exocsyt subunit 70a1‐1 (exo70a1‐1),calcium‐dependent protein kinase11‐2 (cpk11‐2) and g‐box binding factor2‐2 (gbf2‐2) roots. (b) Root hair length measurements of 7‐d‐old wild‐type (Col‐0 roots), sac1‐2, prx7‐1, exo70a1‐1, cpk11‐2 and gbf2‐2 roots (n = 15). (c) Images of 7‐d‐old roots of wild‐type (Col‐0) and plants transformed with 35S:SAC1, 35S:PRX7, 35S:CPK11 and 35S:GBF2; (d) root hair length measurements of wild‐type (Col‐0) and plants transformed with 35S:SAC1, 35S:PRX7, 35S:CPK11 and 35S:GBF2 (n = 15). Error bars represent SEM. *, P < 0.05; ***, P < 0.001 by Student's t‐test.
