Figure 2: In vivo fungicidal activity of the peptides TrxAq-AMP and Pses3. The peptides were tested against Penicillium digitatum by evaluation of lesions formed on fresh Valencia oranges. Fruits were injured, inoculated with a mixed suspension of conidia (2×105 conidia/ml) with peptide at various concentrations and incubated at 20°C for 7 days at 90% relative humidity.
