Embryonic lethality in heterozygous rus6/ + plants. a and b Developing siliques with embryos around mid-bent-cotyledon stage to late-bent-cotyledon stage from a rus6-1/ + plant (a) and a rus6-2/ + plant (b) were examined for seed development. c Siliques from WT were used as a control. Normal developing seeds are green and round. White (arrow) and brown (triangle) seeds, indicative of embryo lethality, are present in the siliques of rus6-1/ + and rus6-2/ + plants. Bar = 1 mm
