Expression patterns of WOX12 and WOX7 during adventitious rooting. A, System of de novo root organogenesis used in this study (Chen et al., 2014). B to F, GUS staining of WOX12pro:GUS in leaf explants at time 0 (B), 1 DAC (C), 3 DAC (D), 4 DAC (E), and 5 DAC (F). G to K, GUS staining of WOX7pro:GUS in leaf explants at time 0 (G), 1 DAC (H), 3 DAC (I), 4 DAC (J), and 5 DAC (K). White asterisks in D and I indicate transient step in which root founder cells are undergoing cell division to form root primordium. Black asterisks in E indicate dome-shaped root primordia. RC, regeneration-competent cell; RF, root founder cell; RP, root primordium. Bars = 1 mm (A) and 50 μm (B–K).
