Fig. 1. Phenotypes of dek1 mutant kernels. (A) dek1-388 mutant kernel. (B) dek1-D mutant kernel. (C) Medial cut through a wild-type (left) and dek1-1394 mutant (right) kernel. (D) Wild-type endosperm and aleurone. (E) dek1-792 mutant endosperm. (F,G) Section of a wild-type embryo and endosperm at (F)7 DAP and (G) 12 DAP. (H,I) Section of a dek1-792 embryo and endosperm at (H) 7 DAP and (I) at 12 DAP. Black arrows indicate embryos; white arrows designate transfer cells. Scale bars: 100 µm (D,E); 200 µm (F,H); 500 µm (G,I).
