Figure 6. Constitutive expression of ERF5 or ERF6 reduces UVC-induced PR-1 expression.
Twelve-day old seedlings were irradiated with 5 kJ m−2 of UV-C and harvested for RNA extraction after 24 h. Relative accumulation of PR-1 (At2g14610) mRNA was measured by qRT-PCR. Relative Quantitation (RQ) values were calculated for PR-1 after normalization to At4g24410 expression levels. Each value is the mean of three technical replicates and the data are representative of two independent experiments. The 35S lines analysed were 35S:ERF5 line 1 and 35S:ERF6 line 6.
