Fig. 5. Phenotypes of wild-type (A), AFI::DEF/GLO (B), ap3 (C) and ap3; AFI::DEF (D,E) Arabidopsis flowers. In E a sepal has been removed to reveal immature petals and stamens. Incomplete suppression of sub-epidermal chlorophyll synthesis by the epidermal transgenes in the petaloid first whorl of wild-type flowers (B) and in the second whorl of ap3 mutant flowers (D,E) is revealed by the slightly green colour of the organs compared to the white colour of mature petals (A,B). Note the immature stamens in the centre of AFI::DEF/GLO flowers in B (viewed by SEM in Fig. 7D) and immature petals and stamens in the ap3; AFI::DEF flowers in D and E (viewed by SEM in Fig. 6C).
