SEM analysis of wild-type and ipe1 anthers at the mature pollen grain stage. A and B, The ipe1 anther (B) is smaller and wilted than the normal anther (A). C to E, Abundant mature pollen grains are observed in the wild type (C) but have vanished in the mutant (E). A wild-type pollen grain is shown in D. F to I, The outer (F) and inner (H) surfaces of wild-type anther compared with the outer (G) and inner (I) surfaces of ipe1 anther. The ipe1 anther outer surface is glossy with no Ubisch bodies on the inner anther surface. Bars = 600 μm in A and B, 400 μm in C and E, 15 μm in D, 6 μm in F and G, and 2 μm in H and I.
