Expression Analysis of PR Genes PR-3, PR-4, and PDF1.2.

Transcript levels of PR-3, PR-4, and PDF1.2 genes were determined by Q-RT-PCR from cDNAs generated from aerial parts of three plants per genotype at 0, 5, and 12 DAI. The expression values of the genes were normalized using the expression level of two housekeeping genes considered as internal standards. Mean expression and sd values were calculated from the results of two independent experiments (triplicate samples of three plants were taken at each time point). (a) Col-0 (RD19 RRS1-S), (b) Nd-1(RD19 RRS1-R), (c) rd19 mutant (F3-1 line, rd19 RRS1-R), (d) RD19g-1 line (rd19 RRS1-R mutant complemented with RD19).
