Light Microscopy Images of Seeds from Crosses with hemiMETI a/s Pollen Parents.
(A) Seeds from a [fie-1/FIE × FIE/FIE; METI a/s] cross. All seeds are plump, indicating that fie-1 mutant seeds are rescued by a pollen parent hemizygous for the METI a/s construct. The two size classes are shown.
(B) Seeds from a [fie-1/FIE × fie-1/FIE; METI a/s] cross. The presence of many shriveled seeds (sh) suggests that some fie-1 mutant seeds have not been rescued.
