Comparative expression analysis of SA- and JA-responsive marker genes in Col-0, ocp3-1 and npr1-1 genetic backgrounds. (a) Time-course gene expression by RT-PCR of some SA- (PR1, PR2 or PR5) and JA- (PDF1.2a) marker genes in response to Pst DC3000 infection. Gels were satined with ethidium bromide. (b) Time-course gene expression by qRT-PCR of PR1and PDF1.2a marker genes in response to Pst DC3000 infection. Open circles represent expression level in Col-0 plants, filled circles represent expression level in ocp3-1 and triangles represent expression level in npr-1. The experiments were repeated three times with cDNAs derived from independent biological samples. The housekeeping gene eIF1α was used as reference.
