Phenotypes of syd brm Double Mutants.
(A) Siliques of selfed syd brm/++, syd/+, brm/+, and the Ler wild-type plants. Parental genotypes are indicated in each panel. Several misshapen and shrunken seeds are indicated by a red arrow, and unfertilized ovules are marked with an asterisk.
(B) Average percentage (mean number plus se of the mean) of misshapen and shrunken seeds in each silique after selfing. Genotypes are indicated below the graph. The total number of seeds counted (n) is shown in Table 4.
(C) Representative cleared embryos from a misshapen seed (right) of selfed syd brm/++ siliques and a wild-type-looking sibling (left) from the same silique. Embryos are arrested at the heart stage (right) or earlier (data not shown).
