Figure 4

Ovules of ucn-1 ett-1 and ucn-1 ett-1 arf4-1 mutants show additive phenotypes. Scanning electron micrographs of early stage 4 ovules are depicted with the exception of (C, F) which show gynoecia of stage 14 flowers. (A) Wild-type ovule. (B) ucn-1 ovule. Arrows highlight protrusions. (C) Typical gynoecium of an ett-1 flower. (D) ett-1 ovule. (E) Additive phenotype of a ucn-1 ett-1 double mutant ovule. Note the protrusions (arrows). (F) Typical gynoecium of an ett-1 arf4-1 flower. (G) ett-1 arf4-1 ovule. Not noticeably different from an ett-1 ovule (compare with D). (H) Additive phenotype of a ucn-1 ett-1 arf4-1 triple mutant ovule. Not noticeably different from a ucn-1 ett-1 double mutant ovule (compare with E). Arrows mark protrusions. Scale bars: 20 μm.
