【Objective】Cucumber Fusarium wilt, caused by Fusarium oxysporum f. sp. cucumerinum, is an important disease in cucumber(Cucumis sativus L.) and can result in serious economic loss. The objective of this study is to investigate the functions of phospholipase C4(PLC4) in F. oxysporum.【Method】Chromosomal location of the FoPLC4 and structure of FoPLC4 were analyzed by bioinformatics methods. Based on the F. oxysporum f. sp. lycopersici genome database, the FoPLC4 was cloned using specific primers. The gene repl...
