Deoxynivalenol (DON) production in liquid cultures of the wild‐type (WT) and Δare A mutant
| Strain | DON production (ppm)b | |
|---|---|---|
| NaNO3 | Arginine | |
| PH‐1 (WT) | 6.2 ± 2.1A a | 2348.2 ± 156.8A |
| RH12 (ΔareA) | 1.7 ± 0.4B | 164.6 ± 32.5B |
a
Data from three replicates were analysed with the protected Fisher's least‐significant difference (LSD) test. Different letters are used to mark statistically significant differences (P = 0.05).
b
DON production in liquid medium with 5 mm NaNO3 or arginine as the nitrogen source was assayed as described by Gardiner et al. (2009a).
