GzSNF1Is Required for Normal Sexual and Asexual Development in the AscomyceteGibberella zeae

The sucrose nonfermenting 1 ( SNF1 ) protein kinase of yeast plays a central role in the transcription of glucose-repressible genes in response to glucose starvation. In this study, we deleted an ortholog of SNF1 from Gibberella zeae to characterize its functions by using a gene replacement strategy. The mycelial growth of deletion mutants (ΔGz SNF1 ) was reduced by 21 to 74% on diverse carbon sources. The virulence of ΔGz SNF1 mutants on barley...
