Figure 2From: WRKY Transcription Factors Involved in Activation of SA Biosynthesis GenesEffect of WRKY28 and WRKY46 on the expression of endogenous Arabidopsis genes. Expression of ICS1, PBS3, WRKY28, WRKY46 and four household genes in Arabidopsis protoplasts was measured by qRT-PCR. Expression of each gene was measured in protoplasts transfected with the empty pRT101 vector (minus sign) or with the pRT101 vector containing 35S::WRKY28 (W28) or 35S::WRKY46 (W46) expression constructs. Bars represent the average level of mRNA accumulation observed in three experiments. mRNA levels in protoplasts transfected with the empty pRT101 vector were taken as 100%. The control represents the average of the data obtained with the four household genes. Error bars represent the SEM.Back to article page
