ABSTRACT
Ustilago maydis, a basidiomycete that infects Zea mays, is one of the top ten fungal models for studying DNA repair, signal transduction pathways, and dimorphic transitions, among other processes. From a metabolic point of view, U. maydis lacks fermentative capacity, pointing to mitochondria as a key player in central metabolism. Oxidative phosphorylation, synthesis of heme groups, Krebs cycle, ß-oxidation of fatty acids, and synthesis of amino acids are some of the processes that take place in mitochondria. Given the importance of this organelle in eukaryotic cells in general, and in fungal cells in particular, we present a protocol for the isolation of U. maydis mitochondria based on the enzymatic disruption of U. maydis cell wall and differential centrifugation. The method can easily be extrapolated to other fungal species, by using appropriate lytic enzymes.
