(A–C) Wild-type embryo sac and seed development; (D–F) aberrant development in a class of cdka;1 fbl17 mutant plants. (A) Wild type showing a typical cellular morphology (arrowheads pointing to the central cell nucleus and the egg cell nucleus from top to bottom, respectively). Aberrant morphologies in the cdka;1^+/− fbl17^+/− double mutant with one (D), or two (G) nuclei in the absence of a cellularized egg apparatus. (B) While the wild-type seed 3 days after pollination has a normal embryo and endosperm development, the double mutant seed development collapsed after pollination, with only one (E) or two (H) nuclei staying in the middle of the empty embryo sac. (C) Wild type showing normal seed development 6 days after pollination, while cdka;1^+/− fbl17^+/− double mutants show approximately 24% seed abortion (F) after pollination with the wild-type pollen.
