Figure 5From: Fungal-associated NO is involved in the regulation of oxidative stress during rehydration in lichen symbiosisNO content of rehydrated R. farinacea thalli. Fluorescence microscopy of thalli of R. farinacea rehydrated with deionized water and 200 μM DAN. Blue fluorescence evidence NO presence, red fluorescence is due to the photobiont's chlorophyll in all cases. Micrographs are representative of several images corresponding to independent samples.
