Fig. 3. Complementation of the pfs2 mutant. (A) Fruit length was reduced in pfs2-1 mutants. In pfs2-1 mutants that were transformed with a wild-type copy of the PFS2 gene (complemented), fruit size and fecundity were identical to wild type (wt). (B) pfs2 mutant ovules. (C) In pfs2 mutants that contained the PFS2 transgene, many ovules were indistinguishable from wild type, but (D) some ovules exhibited subtle changes in outer integument (oi) morphology. (E) Wild-type ovule. Scale bars: 20 µm. f, funiculus; ii, inner integument.
