The gametophytic function of AtDRE2 and developmental fate of FWA-GFP and seed phenotype classes in atdre2-2^+/−;pFWA-GFP. (A–G) Representative images of FWA-GFP classes (A–C and D–G, Left) and the corresponding Nomarski cleared ovules/seeds (A–C and D–G, Right), in unfertilized ovules at 2 DAE (A–C), in seeds at 3 DAmP with WT pollen (D–G), and at 14 DAmP (H–K). The ovules/seeds cleared separately based on the GFP class. Percentages represent the proportion of each segregating GFP class out of a total number (n) of ovules/seeds. Curly brackets represent developmental fate, and the text presents phenotypic nomenclature. Unfert, unfertilized. Egg cell (A–C and F–G) and embryo (F) nuclei are shown in red, and central cell (A–C) and endosperm (D–G) nuclei are in blue. (Scale bars: 50 μm.)
