Expression patterns of CER3 in ceriferous tissues of the wild-type Ws and gcn5-2 mutant. (A) Spatial expression patterns of the CER3 gene in transgenic Ws and gcn5-2 plants harboring the CER3 promoters fused to the GUS gene. Promoter activity was visualized through histochemical GUS-staining in stems, siliques, flowers, and young leaves of 6-week-old plants. Scale bars: stems and siliques, 1.5 mm; flowers and leaves, 2 mm. (B) Quantification of the GUS activity using 4-methylumbelliferone (4-MU) as a substrate and (C) CER3 expression levels in stems, siliques, flowers, and young leaves of 6-week-old plants. Data are means (±SD) from three biological replicates. **P<0.01; Student’s t-test.
