Abstract A fungal effector that is toxic to plant cells was identified in Verticillium dahliae. The effector contains a non-canonical Common in several Fungal Extracellular Membrane proteins (CFEM) domain, a tandem repeat region consisting of four 14-amino acid repeats rich in proline, and a C-terminal region, thus is designated V. dahliae tetrapeptide repeat protein (VdTRP). The membrane targeting of VdTRP is vital for its cell toxicity. CFEM mediates the membrane targeting and the tandem repeat region exerts the toxic function upon cell membrane. The chitinase-like 1 (CTL1), an essential apoplastic protein of cotton, can redirect VdTRP from cell membrane to apoplast. Transgenic cotton overexpressing CTL1 greatly enhances cotton resistance to V. dahliae without affecting cotton growth and development, implicating its potential application in breeding cotton with high wilt resistance. Our data demonstrates that genetic manipulation of effector target constitutes potential strategy for improving crop resistance to fungal pathogens. |
