PAF, which is produced by the filamentous fungus Pencicillium chrysogenum, is a small antifungal protein, triggering ROS-mediated apoptotic cell death in Aspergillus nidulans. In this work, we provide information on the function of PAF in the host P. chrysogenum considering that carbon-starving cultures of the Δpaf mutant strain showed significantly reduced apoptosis rates in comparison to the wild-type (wt) strain. Moreover, the addition of PAF to the Δpaf strain resulted in a twofold increase in the apoptosis rate. PAF was also involved in the regulation of the autophagy machinery of this fungus, since several Saccharomyces cerevisiae autophagy-related ortholog genes, e.g. those of atg7, atg22 and tipA, were repressed in the deletion strain. This phenomenon was accompanied by the absence of autophagosomes in the Δpaf strain, even in old hyphae.
