Size variation in the endosperm nuclei of the b1 b2 seeds without fertilization of the central cell. (A–D) Endosperm development after b1/+ b2/b2 pistils were pollinated with pollen of the CDC2A/cdc2a-1 plant. Four types of seeds were observed at 2 DAP. (A) Type A seed. (B) Type B seed. (C) Type C seed. (D) Type D seed. The number of each type of seed observed in two siliques is shown in each panel. (E) Wild-type seed produced by fertilization of a wild-type female gametophyte with CDC2A pollen at 2 DAP. (F) The b1 b2 seed produced by fertilization of a b1 b2 female gametophyte with wild-type pollen at 2 DAP. (G) The cdc2a seed produced by fertilization of a wild-type female gametophyte with cdc2a-1 pollen. (B, D and F Insets) Enlarged images of the framed areas. (Scale bars, 20 μm.)
