Fig 1. Spatial expression pattern of OsWOX4 detected by in situ hybridization and the effect of continuous downregulation of OsWOX4 on leaf growth.

Fig 1

(A) to (E) Spatial expression pattern of OsWOX4 in the wild-type shoot apex. Cross-sections (A to D) and a longitudinal section (E). Cross-section A and C lies above and below the section containing the meristem (B), respectively. Arrowheads indicate the region where differentiation of large vascular bundles should initiate, and arrows indicate developing large vascular bundles. M, SAM; LV, large vascular bundle; SV, small vascular bundle. (F) and (G) Phenotype of the mock- (F) and DEX- (G) treated seedlings. Transgenic plants carrying pACT1-GVG>OsWOX4:RNAi were treated with DEX for 5 days from germination. Bars = 20 μm in (A) to (C); 50 μm in (D) and (E); 1 cm in (F) and (G).
