Figure 5. Relative expression levels of CYP79B2 (A) and CYP83B1 (B) in abi5-7 treated with glucose or sorbitol.

Ten-day-old Arabidopsis seedlings were treated with 3% glucose or sorbitol, and then the whole plantswere harvested 18 h after treatment. Each data point represents the mean of five independent biological replicates per treatment (mean ± SE). Values not sharing a common letter are significantly different at P < 0.05. Relative expression values are given compared with Col-0 seedlings treated by water.
