Fig. 6. Morphological analysis of the inflorescence of the wild type and CmBES1-overexpressing transgenic lines at the 2 and 4 mm stages.

a1, a2 Top view of the inflorescence at the 2 mm stages. Bar: 1 mm. b1, b2 Side view of the inflorescence at the 2 mm stage. Bar: 1 mm. c1, c2 SEM images of ray florets at the 2 mm stage. Bar: 100 μm. d and v in red letters represent dorsal and ventral petals, respectively. d1, d2 Top view of the inflorescence at the 4 mm stage. Bar: 1 mm. e1, e2 Side view of the inflorescence at the 4 mm stage. Bar: 1 mm. f1, f2 SEM images of ray florets at the 4 mm stage. Bar: 100 μm. d and v in red letters represent dorsal and ventral petals, respectively. Ectopic expression of CmBES1 increased the corolla tube merged degree
