The phenotype of Ubi1::miR393. a Identifying the transgenic plants. The expression of OsmiR393a, OsTIR1 and miR390 was measured by qRT-PCR. “#-number” represents different transgenic lines. *, Significant difference at P < 0.05 compared with the wild type by Student’s t-test (n = 3; means ± SDS). b Comparison of adult phenotypes between the wild type and Ubi1::miR393a. Bars = 50 cm. c Comparison of the root systems of 2-week-old seedlings between the wild type and Ubi1::miR393a. Bars = 2 cm. d Comparison of the primary roots of 4-week-old seedlings between the wild type and Ubi1::miR393a. Bars = 5 mm. e Comparison of the root systems between the wild type and Ubi1::miR393 after their seeds geminating and growing in N₆ liquid medium with 10 μM IAA for three weeks. Bars = 2 cm
