Alteration of the bZIP60/IRE1 Pathway Affects Plant Response to ER Stress in Arabidopsis thaliana
Figure 6
Root growth in response to DTT treatment in mutants and transgenic lines.
Root length measured three d after sowing on MS medium supplemented with indicated concentrations of DTT in WT, mutant (A), IRE1b RNAi lines (B), lines over-expressing bZIP60 full-length (C), and lines over-expressing bZIP60 spliced (D). Values correspond to averages of biological replicates and corresponding standard errors. Student's t-tests were performed to assess the significance of the results for the different lines compared to WT. Statistically significant comparisons are indicated on the graphs with * and ** denoting respectively a p-value ≤0.05 and 0.01.
