Fig. 1. Expression of PR1 and PDF1.2 genes in iturin A treated leaves. Transcription levels of PR1 (A) and PDF1.2 (B) in iturin A treated rosette leaves of wild Col-0, npr1-5 mutant, and
atmyc2 mutant were estimated by real-time RT-PCR. b-Actin was used as internal control. Data were calculated as gene expression relative to b-actin gene expression. Data indicate
means ± standard deviations of independent triplicate experiments.
