Progress in pathogenesis research of Ustilago maydis, and the metabolites involved along with their biosynthesis

Ustilago maydis is a pathogenic fungus that causes corn smut. Because of its easy cultivation and genetic transformation, U. maydis has become an important model organism for plant-pathogenic basidiomycetes. U. maydis is able to infect maize by producing effectors and secreted proteins as well as surfactant-like metabolites. In addition, the production of melanin and iron carriers is also associated with its pathogenicity. Here, advances in our understanding of the pathogenicity of U. maydis, the metabolites involved in the pathogenic process, and the biosynthesis of these metabolites, are reviewed and discussed. This summary will provide new insights into the pathogenicity of U. maydis and the functions of associated metabolites, as well as new clues for deciphering the biosynthesis of metabolites.
