Phenotypes of OsCIN1-OE and GIF1-OE plants. (A) The GIF1-OE plants produced badly-filled grains (right), compared to the empty vector control (left). (B) The OsCIN1-OE plants produced grains completely filled (right). (C) Smaller seeds of the GIF1-OE plants (right), compared to the empty vector control (left). (D) The OsCIN1-OE seeds exhibited preharvest sprouting, while the control seeds did not germinate on panicle at the same time. (E) The GIF1-OE plants grew dwarfing in comparison with the control. (F) The OsCIN1-OE plants were morphologically similar to the control.
