FIG. 2.

Conidia of the ΔpkaR mutant harbor respiring mitochondria in the absence of a germinant. Conidia that were either freshly harvested (A) or incubated for 4 h in YG medium at 37°C (B) were stained with the fluorescent dye Mitotracker Orange. Active mitochondria stain orange. Corresponding bright-field and fluorescent images are shown.
