Expression of early PAMP-responsive genes. Relative expression levels of FRK1 (At2g19190), CYP81F2 (At5g57220), NHL10 (At2g35980), and PHI1 (At1g35140) were analysed in Arabidopsis by quantitative PCR. Leaves were treated with 2 µl of Pieris brassicae egg extract for 3h and 9h before RNA extraction. Expression levels were normalized with respect to the housekeeping gene EIF4A (At3g13920). Data bars represent the mean (±SE) of three technical repeats. This experiment was repeated once with similar results.
