Maize gene expression during infection with Ustilago maydis strains SG200Dpit1 and SG200Dpit2

ABSTRACT: Ustilago maydis is a basidiomycete fungus that causes smut disease in maize. Most prominent symptoms of the disease are plant tumors, which can be induced by U. maydis on all aerial parts of the plant. We identified two linked genes, pit1 and pit2, which are specifically expressed during plant colonization. Deletion mutants for either pit1 or pit2 are unable to induce tumor development and elicit plant defense responses. We used the Affymetrix maize genome array to analyze the transcriptional responses of maize to deletion pit1 and pit2 mutants and found plant responses to both mutants being not significantly distinguishable. U. maydis infected parts of maize seedling leaves were dissected 4 days after inoculation with strain SG200Dpit1 and SG200Dpit2, respectively. We previously submitted
