Figure 3. E. amylovora siderophore production at 28 °C (A), 14 °C (B) and 4 °C (C) in minimal medium ABN-Fe after 1, 3 and 7 dpi.
Vertical lines mark the SD. The two-way ANOVA analysis of these results showed that differences of siderophore production among the three temperatures were very significant (p < 0.0001). These data show the results from a representative experiment performed in duplicate and repeated twice, with similar results.
