Phenotypic features of the maize dek44 mutant. A, F2 ear of dek44 × B73 15 d after pollination (DAP) and randomly selected dek44 and wild-type (WT) kernels in a segregating F2 population 15 DAP. The red arrow identifies a dek44 kernel. Bars = 5 mm. B, Mature F2 ear of dek44 × B73 population. The red arrow identifies a dek44 kernel. Bars = 10 mm. C, Longitudinal sections of dek44 and wild-type mature kernels at 15 DAP. Bars = 500 μm. D, Comparison of 100-grain weight of randomly selected mature dek44 and wild-type kernels in a segregating F2 population. Values are means with se, n = 3 individuals (***, P < 0.001, Student’s t test). E, Paraffin sections of 15- and 18-DAP dek44 and wild-type kernels. Em, Embryo; En, endosperm. Bars = 500 μm. F and G, Microstructure of developing starch endosperm (SE) and BETL of dek44 and wild-type kernels (15 DAP). PC, Placento-chalazal region. Bars = 100 μm.
