The overexpression of BOP1 or BOP2 produces more response to MeJA. (a) 35S:BOP1 and 35S:BOP2 lines  and their controls were tested as described in Figure 1. One asterisk means a significant difference with P<0.05, and two asterisks means P<0.01 (Student’s test of one tail). (b) Silencing of the overexpression lines. 35S:BOP1 and 35S:BOP2 lines were phenotyped at the time of bolting as having a characteristic phenotype (Phen.)  or being wild type (No Phen.). Then, RNA was extracted from several plants and the levels of the transgenes quantified as described in Figure 5c. On the left side of the plot, relative expression of BOP1 and, on the right, relative expression of BOP2. Means with the same letter are not significantly different (Fisher's LSD test, P<0.05). The test was performed separately for each gene.
