子囊菌Fusarium oxysporumf.sp.cubenserace 4（Foc TR4）引起香蕉（Musaspp.）在本研究中，研究了SGE 1在调节Foc TR 4的生长、分生孢子和致病性中的作用。SGE 1基因的缺失不影响Foc TR4的营养生长，但影响其产孢。SGE 1缺失突变体对香蕉苗的致病性基本丧失。显微镜下观察表明，SGE 1缺失突变体的渗透和定殖过程严重受损。蛋白质组学分析表明，SGE1调控Foc TR4的一系列蛋白质的产生。综上所述，我们的研究结果表明，SGE1在真菌病原菌Foc TR4的分生孢子形成和致病性中起着重要的作用。
The ascomycete fungusFusarium oxysporumf.sp.cubenserace 4 (Foc TR4) causes vascular wilt diseases in banana (Musaspp.). In the present study, the role of SGE1 in regulating growth, conidiation, and pathogenicity of Foc TR4 was investigated. Deletion ofSGE1did not influence vegetative growth but impaired the conidiation of Foc TR4. Besides, theSGE1deletion mutant basically lost pathogenicity on banana plantlets. Observation under the microscope indicated that the penetration and colonization processes were severely impaired in theSGE1deletion 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.
