ABSTRACT
Adaptation to the environment is a requirement for the survival of every organism. For pathogenic fungi this also implies coping with the different conditions that occur during the infection cycle. After detecting changes to external media, organisms must modify their gene expression patterns in order to accommodate the new circumstances. Control of gene expression is a complex process that involves the coordinated action of multiple regulatory elements. Chromatin modification is a well-known mechanism for controlling gene expression in response to environmental changes in all eukaryotes. In pathogenic fungi, chromatin modifications are known to play crucial roles in controlling host interactions and their virulence capacity, yet little is known about the specific genes they directly target and to which signals they respond. The smut fungus Ustilago maydis is an excellent model system in which multiple molecular and cellular approaches are available to study biotrophic interactions. Many target genes regulated during the infection process have been well studied, however, how they are controlled and specifically how chromatin modifications affect gene regulation in the context of infection is not well known in this organism. Here, we analyse the presence of chromatin modifying enzymes and complexes in U. maydis and discuss their putative roles in this plant pathogen in the context of findings from other organisms, including other plant pathogens such as Magnaporthe oryzae and Fusarium graminearum. We propose U. maydis as a remarkable organism with interesting chromatin features, which would allow finding new functions of chromatin modifications during plant pathogenesis.
