FIGURE 6.

Effect of different light treatments on hypocotyl length (A) and anthocyanin content (B) of 7-day-old seedlings of wild type (WT), hy5 mutant and PpHY5/hy5 transgenic plant. Seedlings were grown under continuous weak white light (WWL, 40 μw/cm²) supplemented with/without UVA (40 μw/cm²) or UVB (10 μw/cm²) or both together for different UV light treatments. For Arabidopsis transgenic plant, three independent lines were used. Data were presented as means (±SE) from three independent biological replicates with 30 or more Arabidopsis seedlings collected for each replicate. Values labeled with different letters indicated a significant difference at P < 0.05.
