Figure 4. Total indolic glucosinolate content and relative expression levels of MYB34, MYB51, and MYB122 in abi5-7 treated with glucose or sorbitol.

Ten-day-old Arabidopsis seedlings were treated with 3% glucose or sorbitol, and then the whole plants were collected 3 days (A) or 18 h (B–D) after treatment. Each data point represents the mean of five (for qPCR assay) or six (for glucosinolate assay) 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.
