Over-expressing GhmiR157 suppressed floral organ development. a Image of developing floral buds from different fruit branches. b Kinematic analysis of the developing petal area. c-f Images of the petal (c), bract (d), stamen and gynoecium (e) and sepal (f) from opened flowers of Control (left), OV12 (middle) and OV38 (right) plants. g Images of epidermal cells at the adaxial side of mature petals. Scale bar, 100 μm. h and i The number of mature petal cells (h) and the mature petal cell area (i). B2-B10 represent the position of the developing floral buds from the second to tenth fruit branch. Control, nontransgenic plant segregated from 35S::GhmiR157 transgenic lines in cotton. OV12 and OV38, 35S::GhmiR157 transgenic lines in cotton. Different letters indicate statistically significant differences at P < 0.05 based on analysis of variance (ANOVA) (Tukey’s multiple comparison test). The error bars indicate the standard deviation of at least eight biological replicates
