Figure 1. Relative expression levels of MYB34 (A), MYB51 (B), MYB122 (C), CYP79B2 (D), and CYP83B1 (E) in young seedlings treated with glucose or sorbitol for indicated times.

The expression level was measured in 10-day-old Arabidopsis seedlings treated with 3% glucose or sorbitol, and then the whole plants were collected 6, 12, 18, 24, and 36 h after treatment, respectively. Each data point represents the mean of five independent biological replicates per treatment (mean ± SE). Expression level of genes in water-treated seedlings was set to 1. The gene transcription levels upon three treatments were compared for each time point and values not sharing a common letter are significantly different at P < 0.05.
