Transcriptional Activation of PR Genes.

Arabidopsis inflorescence stalks (ecotype Ws-2) were wounded and inoculated with Agrobacterium strain C58 at the base just above the rosette. The number of transcripts of (A) PR3 (At3g12500), (B) PR5 (At1g75040), (C) PR1s (At2g19970), and (D) PR1like (At2g19990) was determined by qRT-PCR and normalized relative to 10,000 molecules of ACTIN2/8 at the indicated time points. Wounded, but not inoculated, stalks served as control. Results shown represent mean values ± se from at least three independent experiments.
