Fig. 9. Phenotypes of PDF2 co-suppression plants. (A) Wild-type flower. (B) Flower of the PDF2 co-suppression plant (line 3). (C,D) SEM views of a stage-nine flower of the wild type (C) and the PDF2 co-suppression plant (D). The adaxial sepal has been removed. (E,F) Longitudinal sections of an apical inflorescence meristem of the wild type (E) and the PDF2 co-suppression plant (F). (G-N) SEM views of epidermal cells of the wild type (G,I,K,M) and PDF2 co-suppression plants (H,J,L,N). Epidermal cells of the adaxial side of stage-nine petals (G,H), the adaxial side of stage-13 petals (I,J), the abaxial side of stage-13 petals (K,L) and the adaxial side of stage-nine sepals (M,N) are shown. Scale bars: 25 µm in E,F; 10 µm in G-L; 50 µm in M,N.
