NsdD is involved cell wall stress resistance. (A) An nsdDΔ strain displays hyphal tip swelling (arrows) in the presence of Congo red, which occasionally results in bursting and the apparent release of hyphal contents. (B) The nsdD deletion mutant is less sensitive toward nikkomycin Z. Aliquots of 5 μl from serial dilutions of conidial suspensions (4 × 10⁶ to 4 × 10³ ml⁻¹) were spotted on minimal medium containing 32 μg/ml nikkomycin Z and allowed to grow at 37°C for 2 days. Two independent nsdDΔ isolates are shown.
