Figure 4

Oxidative stress assays. Photomicrographs of F. solani cells after oxidative stress assays by fluorescence microscopy using the probe 2,7-dichlorofluorescein diacetate (H₂DCFDA). The cells were treated with FLC, Cc-LTP2, Cc-LTP2 plus FLC, Cc-GRP, or Cc-GRP plus FLC for 24 h and then assayed for oxidative stress. Control cells were treated only with H₂DCFDA. Bars: 20 µm.
