Phenotypic observations and reporter assays of 11700Rep^YFP in the mir390/11700^ge mutants and MIR390/11700^OE plants. (A) Secondary structure prediction of the wild type and edited miR11700 precursors. The mature sequence is highlighted in red and the star sequence is highlighted in blue. The mir390^ge mutant was used as the genetic background to mutate miR11700. Northern blotting of miR390 and miR11700 in the mir390/11700^ge mutants (B) and MIR390/11700^OE plants (C), respectively. (D) Vegetative growth of the 18-day-old mir390/11700^ge mutants. Scale bars, 1 cm. (E) qRT-PCR analysis of MpCYP78A101 in the gemmae of the mir390/11700^ge mutants. (F) Vegetative growth of the 18-day-old MIR390/11700^OE plants. Scale bars, 1 cm. (G) qRT-PCR analysis of MpCYP78A101 (i) and MpARF2 (ii) in the thallus of MIR390/11700^OE plants. (H) YFP-transient reporter assays of 11700Rep^YFP in the mir390/11700^ge mutants and MIR390/11700^OE plants (i). The YFP intensity was quantified using more than 20 images captured by a fluorescence microscope (ii). Tak-1 was used as a control. Error bars represent the standard error from three biological replicates. (I) Relative cell area ratios of various plants in response to Tak-1 plants without NAA treatment. Epidermal cells in the central region of gemma were used for area calculation.
