The Predicted Secretome of the Plant Pathogenic Fungus Fusarium graminearum: A Refined Comparative Analysis
The fungus Fusarium graminearum forms an intimate association with the host species wheat whilst infecting the floral tissues at anthesis. During the prolonged latent period of infection, extracellular communication between live pathogen and host cells must occur, implying a role for secreted fungal proteins. The wheat cells in contact with fungal hyphae subsequently die and intracellular hypha...
متن کاملCompartmentalized gene regulatory network of the pathogenic fungus Fusarium graminearum
Head blight caused by Fusarium graminearum threatens world-wide wheat production, resulting in both yield loss and mycotoxin contamination. We reconstructed the global F. graminearum gene regulatory network (GRN) from a large collection of transcriptomic data using Bayesian network inference, a machine-learning algorithm. This GRN reveals connectivity between key regulators and their target gen...
متن کاملCharacterization of RNA silencing components in the plant pathogenic fungus Fusarium graminearum
The RNA interference (RNAi) plays a critical role in gene regulation in a variety of eukaryotic organisms. However, the role of RNAi remains largely unclear in plant pathogenic fungi. In this study, we explored the roles of core components of the RNAi pathway in Fusarium graminearum, the major causal agent of wheat head blight. Our results demonstrated that the hairpin RNA (hpRNA) can efficient...
متن کاملGene expression shifts during perithecium development in Gibberella zeae (anamorph Fusarium graminearum), with particular emphasis on ion transport proteins.
Gibberella zeae, the causal agent of Fusarium head blight, is a devastating pathogen of small grains worldwide. The sexual cycle is a crucial component of head blight epidemiology, as forcibly discharged ascospores serve as the primary inoculum. The recent development of an Affymetrix GeneChip containing probesets representative of all predicted genes of G. zeae has opened the door to studies o...
متن کاملSexual Development and Ascospore Discharge in Fusarium graminearum
Fusarium graminearum has become a model system for studies in development and pathogenicity of filamentous fungi. F. graminearum most easily produces fruiting bodies, called perithecia, on carrot agar. Perithecia contain numerous tissue types, produced at specific stages of perithecium development. These include (in order of appearance) formation of the perithecium initials (which give rise to ...
