Fig. 2. GFP-labelled mitochondria in living Neurospora cells. Conidiospores of a strain expressing mtGFP were grown for different time periods in Vogel's liquid minimal medium at 30°C under agitation and subjected to fluorescence (left) and phase contrast (right) microscopy. (A) Conidiospore before germination; (B) newly germinated conidiospore; (C) hyphal tip after 4 hours incubation; (D) hypha after overnight incubation; (E) hyphal branch point after overnight incubation. Bar, 5 µm.
