Validation of computationally predicted differentially expressed genes in PepGMV-infected pepper plants. Relative level of expression measured by quantitative reverse-transcription PCR. Error bars indicate standard deviation of mean for triplicate samples. Expression of β-tubulin was used for data normalization. RRP1 (Kiwellin ripening-related protein); PR5 (thaumatin-like protein); ANN (annexin protein); CPD (carboxypeptidase protein); GST1 (glutathione transferase); OPR1 (12-oxophytodienoate reductase 1); HSP70 (heat shock protein) M: mock; S: symptomatic; R: recovered.
