The WOPR protein Ros1 is a master regulator of sporogenesis and effector gene expression in the maize pathogen Ustilago maydis [ChIP-Seq]

ABSTRACT: Goals: characterization of the transcription factor Ros1 in Ustilago maydis Methods: generation of deletion mutants, microscopic observations, ectopic expression of ros1, identification of Ros1 regulated genes by RNAseq and ChIP sequencing Results: Ros1 is not involved in plant colonization but is essential to trigger sporogenesis during late stages of infection. Premature expression of ros1 revealed that Ros1 counteracts the b-dependent filamentation program and induces morphological alterations resembling the early steps of sporogenesis. Transcriptional profiling and ChIP seq analyses revealed that Ros1 affects the expression of about 30 % of all U. maydis genes with 40% being direct targets. Cell wall remodeling and plasma membrane modifications are among the processes affected by Ros1
