Ectopic expression of the GhmiR157 precursor in Arabidopsis. a Phenotypes of 35S::GhmiR157 transgenic lines in Arabidopsis. b and c Phenotypes of flowers and gynoecium at stage 13. Scale bar (c), 100 μm. d Relative expression of the GhmiR157 precursor in inflorescences. “#”, indicates no expression. R.E.L., the relative expression levels calculated using AtACT7 (AT5G09810.1) as a control. The error bars indicate the standard deviation of four biological replicates. e and f The number of ovules per ovary (e) and the petal area (f). Different letters indicate statistically significant differences at P < 0.05 based on analysis of variance (ANOVA) (Tukey’s multiple comparison test). The error bars (e and f) indicate the standard deviation of at least 15 biological replicates. E4 and E6 indicate 35S::GhmiR157 transgenic lines in Arabidopsis
