Implication

Randomized trial identifies four candidate effector proteins that enhance pathogenicity in oil tea, suggesting new fungicide targets.

Key Points

  • This study aims to identify potential targets for fungicide development to combat oil tea anthracnose caused by Colletotrichum spp.
  • Identified 20 highly expressed candidate effector proteins (CfCEPs) from Colletotrichum fructicola.
  • Conducted yeast secretion tests, transient overexpression assays, and gene deletion analyses to assess CfCEP function.
  • Performed qRT-PCR and subcellular localization analysis to evaluate expression and functional sites of CfCEPs.
  • Four CfCEPs (CfCEP1, CfCEP2, CfCEP7, CfCEP8) directly promote pathogen infection and are suitable targets for fungicide development.
  • These proteins are upregulated during the infection phase and mainly function in the plasma membrane and cytoplasm.
  • Phylogenetic analysis indicates that these CfCEPs are conserved within the Colletotrichum genus.
