| Research Abstract |
Fusarium oxysporum f. sp. cepae (FOC) secretes proteins (NIP8 and NIP8-S) that can induce necrosis of the suspension-cultured host cells when the fungus is treated with antifungal compounds from the host roots. The present study was performed to clarify the roles of these proteins in the pathogenicity of FOC. NIP8 was proved to be a degraded protein fragment of hydrophobin and unrelated to the pathogenicity of FOC. NIP8-S was a basic protein (pI=9.4) of unknown function with three deduced disulfide bridges. Recombinant NIP8-S produced by Escherichia coli induced wilting on the host plants, suggesting that NIP8-S plays a role for causing the symptoms of Fusarium wilt.
