Comparison of the wild-type, ems1 mutant, and revertant plants and flowers. (A) A wild-type plant showing normal seedpods. (B) A mutant plant with small seedpods with no developing seeds. (C) A mutant plant with revertant sectors showing large seedpods (arrow). (D) A wild-type flower showing pollen grains. (E) A mutant flower lacking pollen grains. (F) A close-up view of a revertant flower showing pollen grains. (G) A portion of wild-type anther with functional pollen grains stained in red. (H) A portion of ems1 mutant anther without pollen grains. (I) Microspores from wild-type anther regular in size. (J) Debris from ems1 mutant anther at stage similar to that shown in I. In A, bar, 5 mm. In D, F, bar, 500 μm. In G,I, bar, 10 μm. A–C; D and E; G and H; I and J have same magnification.
