Description
Summary:The Fusarium graminearum (Gibberella zeae) genome sequence has been recently released. The combination of this valuable information with gene prediction software has provided theoretical coding sequences that can be targeted for disruption. Genes with a possible role in perithecium formation and ascospore dispersal have been targeted for disruption. The effect of disruption of trehalose-6-phosphate synthase will be presented. In Magnaporta grisea the disruption of this gene has considerably reduced sporulation and has affected the generation of turgor pressure in appressoria. In addition, several putative light-dependent genes have been disrupted. The effect of these gene disruptions on spore discharge and perithecium formation in F. graminearum will be presented.
