Complementation of the z3 mutation. a Phenotypes of the WT, the z3 mutant, and the 35S::Z3/z3 transgenic plant at 80 DAS grown under natural long day conditions. Leaf variegation and delayed flowering (Additional file 1: figure S1) of the z3 mutation were rescued by the transformation of 35S::Z3 construct. WT flowered around one month earlier than the days to heading data in Additional file 1: figure S1 because the seeds of the WT, the z3 mutant, and the 35S::Z3/z3 transgenic plant in Fig. 5a were sown on June, not in April (Suwon, Korea, 37°N latitude). Arrows indicate the panicle. b Leaf phenotypes of the WT, the z3 mutant, and the 35S::Z3/z3 transgenic plant at 80 DAS grown in the paddy field. c–d Panicle and grain phenotypes of 80-day-old WT, z3 mutant, and 35S::Z3/z3 transgenic plants grown under natural long day conditions. z3 (du), dull-brown colored grain of the z3 mutant; z3 (iv), ivory colored grain of the z3 mutant
