Fig. 5.

Second whorls of wild-type, TfGLO- and TfDEF-suppressed plants viewed by scanning electron microscopy. Adaxial (a) and abaxial (b) surfaces of petals of wild-type torenia. Adaxial (c and e) and abaxial (d and f) surfaces of petals of TfGLO-SRDX plants. Petals of the distinctive serrated region (c and d) and the middle region (e and f) outside the serrated region in TfGLO-SRDX plants. Adaxial (g and i) and abaxial (h and j) surfaces of petals of TfDEF-SRDX plants. Petals of partial decolorized region (g and h) and the middle region (i and j) outside the decolorized region in TfDEF-SRDX plants. Blue arrowheads indicate petal cells that have lost the characteristics of petal cells, i.e., without corn-shaped cells. Red arrowheads indicate petal cells that showed sepal-like cells.
