Abstract
Type 2C protein phosphatases (PP2Cs) play important roles in regulating many biological processes in eukaryotes. Currently,
little is known about functions of PP2Cs in filamentous fungi. The causal agent of wheat head blight, Fusarium graminearum,
contains seven putative PP2C genes, FgPTC1, -3, -5, -5R, -6, -7 and -7R. In order to investigate roles of these PP2Cs, we
constructed deletion mutants for all seven PP2C genes in this study. The FgPTC3 deletion mutant (DFgPtc3-8) exhibited
reduced aerial hyphae formation and deoxynivalenol (DON) production, but increased production of conidia. The mutant
showed increased resistance to osmotic stress and cell wall-damaging agents on potato dextrose agar plates. Pathogencity
assays showed that DFgPtc3-8 is unable to infect flowering wheat head. All of the defects were restored when DFgPtc3-8
was complemented with the wild-type FgPTC3 gene. Additionally, the FgPTC3 partially rescued growth defect of a yeast
PTC1 deletion mutant under various stress conditions. Ultrastructural and histochemical analyses showed that conidia of
DFgPtc3-8 contained an unusually high number of large lipid droplets. Furthermore, the mutant accumulated a higher basal
level of glycerol than the wild-type progenitor. Quantitative rea
