Expression pattern of pWOX2-CENH3-GFP in early megasporogenesis. Representative images of pWOX2-CENH3-GFP fluorescence in early stage megaspores of Arabidopsis thaliana, displaying either the haploid number of five centromeric GFP foci in uninuclear megaspores (A, B and C) or ten GFP signals in binuclear megaspores (D; nuclei are spatially overlapping).
