ERECTA and STOMAGEN Regulate Redox-Mediated Cortex Proliferation through Intercellular Signaling.

(A, C, E) Expression pattern of ERECTA (A), EPFL4 ((C), left), EPFL6 ((C), right), and STOMAGEN ((E), bright field in left and fluorescence in the right), as shown by promoter–reporter transgenes. The reporter gene is GUS in (A) and (C), and VENUS in (E).

(B) Root radial pattern in er-105 mutant expressing ERECTA (ER) in the epidermis ((B), left), the xylem ((B), middle), or the phloem ((B), right) using the promoter of ML1, IRX3, or SUC2, respectively, after 24h of treatment with H2O2.

(D, F) Root radial pattern in the epfl4 epfl6 double mutant (D) or transgenic plants that contain an artificial miRNA targeting STOMAGEN (ST-miR) (F), after 24h of treatment with water (control) or H2O2. c, cortex; mc, middle cortex; e, endodermis. Bars = 20 μm.
