Table 1. IC50 values for rAtPDF2.3 against yeast and plant pathogenic fungi.

Microorganism	IC50 (μM)
Botrytis cinerea B05.10	5.8 ± 0.0
Botrytis cinerea R16	5.8 ± 0.0
Fusarium oxysporum	4.4 ± 1.6
Fusarium culmorum	1.0 ± 0.4
Verticillium dahliae	4.4 ± 1.6
Fusarium graminearum PH-1	1.4 ± 0.0
Saccharomyces cerevisiae BY4741	8.1 ± 0.9

Fungi and yeast were treated with a concentration range of rAtPDF2.3 for 48 or 24 hours, respectively, after which the IC50 values were determined microscopically for fungi and spectrophotometrically for yeast. IC50, the concentration required for 50% growth inhibition as compared to control treatment after either 24 hours for yeast, or after 48 hours for fungi. Data of at least three independent experiments are shown (n ≥ 3).
