Transgenic plants constitutively expressing PROPEP peptide precursor genes in both PR-1 and PDF1.2

Transgenic plants	Relative expression levels
	PROPEP1	PROPEP2	PR-1	PDF1.2
35S::PROPEP1	17.2 ± 1.7		3.2 ± 1.9	4.4 ± 0.5
35S::PROPEP2		76.7 ± 23.8	3.4 ± 2.0	4.3 ± 1.3

Relative expression of PR-1 and PDF1.2genes in 35S::PROPEP plants as compared with basal levels in untreated wild-type plants is shown. Comparative expression levels were determined by semiquantitative RT-PCR analysis with β-tubulin expression as a control. Results are derived from four different experiments using at least six independent lines per construct.
