Loss of function of OsUGE2 decreases the cell length. A Shoot morphology of NIP, KO1 and KO2 grown in normal YNS hydroponic culture for 18 days. Bars = 5 cm. B Display of leaf color of NIP, KO1 and KO2 grown in normal YNS hydroponic culture for 18 days. C Root morphology of NIP, KO1 and KO2 grown in normal YNS hydroponic culture for 18 days. Bars = 2 cm. D Statistical analysis of shoot length (SL), total root number (TRN) and root length (RL) in NIP, KO1 and KO2 grown in normal YNS hydroponic culture for 18 days. The unit for SL and RL were centimeter (cm). At least 12 plants were measured for each genotype. E Statistical analysis of fresh weight of shoot and root in NIP, KO1 and KO2 cultivated in normal YNS hydroponic culture for 18 days. At least 12 plants were measured. F The cell length of inner-epidermal cells of leaf sheaths staining with 0.5% toluidine blue. The double arrow indicated the cell length. 3-week-old seedlings grown in normal YNS hydroponic culture were used. Bars = 100 μm. G The longitudinal (up) and cross sections (down) of roots with 3-week-old seedlings grown in normal YNS hydroponic culture. Bars = 100 μm. H–J Statistical analysis of cell length of inner-epidermal cells of leaf sheaths (H), Root cell length (I) and root diameter (J). Six plants were used for each genotype. Data were means ± SEM. Asterisks indicated significant differences according to Student’s t test (P ≤ 0.05**)
