Heat shock protein 90 is required for sexual and asexual development, virulence, and heat shock response in Fusarium graminearum
Eukaryotic cells repress global translation and selectively upregulate stress response proteins by altering multiple steps in gene expression. In this study, genome-wide transcriptome analysis of cellular adaptation to thermal stress was performed on the plant pathogenic fungus Fusarium graminearum. The results revealed that profound alterations in gene expression were required for heat shock r...
متن کاملFusarium graminearum Tri12p influences virulence to wheat and trichothecene accumulation.
The gene Tri12 encodes a predicted major facilitator superfamily protein suggested to play a role in export of trichothecene mycotoxins produced by Fusarium spp. It is unclear, however, how the Tri12 protein (Tri12p) may influence trichothecene sensitivity and virulence of the wheat pathogen Fusarium graminearum. In this study, we establish a role for Tri12 in toxin accumulation and sensitivity...
متن کاملGlycosylphosphatidylinositol-Anchored Proteins in Fusarium graminearum: Inventory, Variability, and Virulence
The contribution of cell surface proteins to plant pathogenicity of fungi is not well understood. As such, the objective of this study was to investigate the functions and importance of glycosylphosphatidylinositol-anchored proteins (GPI-APs) in the wheat pathogen F. graminearum. GPI-APs are surface proteins that are attached to either the membrane or cell wall. In order to simultaneously disru...
متن کاملWetA is required for conidiogenesis and conidium maturation in the ascomycete fungus Fusarium graminearum.
Fusarium graminearum, a prominent fungal pathogen that infects major cereal crops, primarily utilizes asexual spores to spread disease. To understand the molecular mechanisms underlying conidiogenesis in F. graminearum, we functionally characterized the F. graminearum ortholog of Aspergillus nidulans wetA, which has been shown to be involved in conidiogenesis and conidium maturation. Deletion o...
متن کاملPhysical and functional interaction of FgFtr1-FgFet1 and FgFtr2-FgFet2 is required for iron uptake in Fusarium graminearum.
FgFtr1 and FgFtr2 are putative iron permeases, and FgFet1 and FgFet2 are putative ferroxidases of Fusarium graminearum. They have high homologies with iron permease ScFtr1 and ferroxidase ScFet3 of Saccharomyces cerevisiae at the amino acid level. The genes encoding iron permease and ferroxidase were localized to the same chromosome in the manner of FgFtr1/FgFet1 and FgFtr2/FgFet2. The GFP (gre...
