Fig. 7. Expression of paternal markers in glc seeds. Embryonic FAC1 and RPS5a expression in wild-type seeds (A,C) and glc seeds (B,D-F) from the promoter activity of paternal FAC1 (A,B), paternal RPS5a (C-E) and maternal RPS5a (F). (A,B) Embryos at the one-cell stage. (C,D,E) Embryos at the globular stage. (F) Embryo at the eight-cell stage. Arrows in A and B indicate the embryo proper. Arrowhead in B indicates the cell wall of the embryo proper. wt, wild-type. Scale bars: 50 µm.
