Fosp9, a Novel Secreted Protein, Is Essential for the Full Virulence of Fusarium oxysporum f. sp. cubense on Banana (Musa spp.).

ABSTRACT: The banana vascular wilt pathogen, Fusarium oxysporum f. sp. cubense, delivers a number of different secreted proteins into host plant tissues during infection. Until now, only a few of the secreted proteins from this fungus have been shown to be virulence effectors. Here, the product of fosp9, which is a gene in this pathogen, was found to be a novel virulence effector. The fosp9 gene encodes a hypothetical 185-amino-acid protein which has a functional signal peptide but contains no known motifs or domains. The fosp9 disruptants displayed a significant reduction in producing wilt symptoms on bananas, indicating that fosp9 is essential for the full virulence of this pathogen for banana. These disruptants did not exhibit a change in either saprophytic grow
