Figure 3. AtICS1 expression is positively regulated by SA and is required for optimal expression of AtRDR1 and PR1 in response to exogenous SA treatment.

Figure 3

(A) RTqPCR analysis of transcript accumulation for AtRDR1 and AtPR1 expression in Arabidopsis ecotype Col-0 wild type (WT), sid2-mutant (compromised in expression of ICS1) and NahG-transgenic plants 6 h post SA treatment. (B) Transgenic Arabidopsis plants harboring the promoter: reporter constructs ICS1:GUS and ICS2:GUS stained for GUS activity 24 h after control (water) or SA treatment. SA treated Col-0 WT and 35S:GUS plants, 24 h after treatment are included as controls. (C) RTqPCR analysis of AtICS1, AtICS2, and AtPR1 transcript accumulation in wild-type plants treated with SA, over a 48 h time course. Error bars represent standard error of the mean.
