FIGURE 6.
Scanning electron micrographs of leaf (A) or wood (B) surface exposed to 30 μM nicosulfuron and colonized (biofilm) or not (control) by P. cucumerina AR1 strain from day 0 (D0; exposure to nicosulfuron) to the end of the experiment (D35). No contamination of the support was observed for control leaf (A) or wood (B) supports throughout the experiment (D0–D35). The support surface is completely covered by P. cucumerina AR1 biofilm before being exposed to nicosulfuron (D0, (A,B)). A fungal development was observed at D10 for leaf (A) and D21 for wood (B) supports with appearance of a more compact and longer mycelium. Scale bars represent 500 μm.
