The ascomycete fungus Fusarium oxysporum f.sp. cubense race 4 (Foc TR4)causes vascular wilt diseases in banana (Musa spp.). In the present study, the role of SGE1 in regulating growth, conidiation, and pathogenicity of Foc TR4 was investigated. Deletion of SGE1 did not influence vegetative growth but impaired the conidiation of Foc TR4. Besides, the SGE1 deletion mutant basically lost pathogenicity on banana plantlets. Observation under the microscope indicated that the penetration and colonization processes were severely impaired in the SGE1 deletion mutant. Proteomics analysis suggested that SGE1 regulated the production of a series of proteins of Foc TR4. Taken together, our results suggest that SGE1 plays an important role in regulating conidiation and pathogenicity in fungal pathogen Foc TR4.
