Fig. 7. Mutagenesis of AP1-binding site causes ectopic expression of AGL24 in young floral meristems. (A) Schematic of the Pro_AGL24:GUS construct where the 4.7 kb Arabidopsis AGL24 genomic sequence was translationally fused with the GUS gene. The native CArG box near the AGL24-4 fragment identified in Fig. 6E was mutated. (B,C) GUS staining in inflorescence apices of the transformants containing Pro_AGL24:GUS (B) and its derived construct with the mutated CArG box (C). At least 12 independent lines for each construct were analyzed and representative images are shown. Scale bars: 100 µm for B,C.
