Ustilago maydis gene expression after growth on hydrophobic surface plus/minus hydroxy fatty acids

ABSTRACT: Infection-related development of phytopathogenic fungi is initiated by sensing and responding to plant surface cues. This response results in the formation of specialized infection structures, so-called appressoria. To unravel the program inducing appressoria in the biotrophic smut fungus Ustilago maydis, we exposed cells to a hydrophobic surface and the cutin monomer 16-hydroxy hexadecanoic acid. Genome-wide transcriptional profiling under these appressorium-inducing in vitro conditions revealed dramatic transcriptional changes in almost 20% of the genes. Comparisons with the U. maydis sho1 msb2 double mutant, lacking two putative sensors for plant surface cues, revealed that these plasma membrane receptors regulate a small subset of the surface cue-induced genes. These genes comprised ma
