Mutant dek47-1 arrests early in maize seed development. (A) The recessive dek47-1 mutant segregated in a self-pollinated ear at 17 days after pollination (DAP). Arrows point to dek47-1 mutant kernels. (B) Maturity ear of self-pollinated dek47-1 heterozygotes. Arrows point to dek47-1 mutant kernels. (C,D) Embryo side of mature kernels of wild-type (C) and dek47-1 (D) kernels at 30 DAP. (E,F) Dissection of mature wild-type (E) and dek47-1 (F) kernels at 30 DAP. (G-M) Paraffin sections of the wild-type (WT) and dek47-1 kernels at 8 and 14 DAP. Wild-type kernels at 8 DAP (G,K) and 14 DAP (I); the dek47-1 kernels at 8 DAP (H,L) and 14 DAP (J,M). Arrows indicate the embryo. en, endosperm; em, embryo; ram, root apical meristem; sam, shoot apical meristem; and sc, scutellum. Scale bars = 1 mm.
