Figure 4.

Phenotypic analysis of Ostrxm RNAi rice plants. A and B, Wild-type and transgenic rice plants are shown at 3 (A) or 10 (B) d postgermination. C, Wild-type and transgenic rice plants grown for 70 d. D, Leaf blade phenotypes of wild-type and transgenic rice plants grown for 70 d. Secondary leaves from primary tillers are shown. E, Main panicle of wild-type and Ostrxm RNAi rice plants grown for 115 d. Wild-type and transgenic rice plants were grown in a growth chamber (A and B) conditioned with 8 h dark/16 h light at 200 μmol m⁻² s⁻¹ and a day/night temperature regime of 30°C/25°C, or under sunlight conditions in a greenhouse (C–E). In each image, wild-type, Vec, and Ostrxm RNAi 4 and 14 plants are arranged from left to right (A–E).
