Positive-strand RNA virus replication invariably occurs in association with host cell membranes, which are induced to proliferate and rearrange to form vesicular structures where the virus replication complex is assembled. In particular, carnation Italian ringspot virus (CIRV) replication takes place on the mitochondrial outer membrane in plant and yeast cells. In this work, the model host Saccharomyces cerevisiae was used to investigate the effects of CIRV p36 expression on the mitochondrial structure and function through the determination of mitochondrial morphology, mitochondrial respiratory parameters, and respiratory chain complex activities in p36-expressing cells. CIRV p36 ectopic expression was shown to induce alterations in the mitochondrial network associated with a decrease in mitochondrial respiration and the activities of NADH-cyt c, succinate-cyt c (C II-III), and cytochrome c oxidase (C IV) complexes. Our results suggest that the decrease in respiratory complex activity could be due, at least in part, to alterations in mitochondrial dynamics. This yeast-based model will be a valuable tool for identifying molecular targets to develop new anti-viral strategies.
