Key Findings
- Researchers at Hebei Agricultural University identified two effectors, AsCEP19 and AsCEP20, that contribute to the virulence of the fungus A. solani, which causes early blight in potatoes and tomatoes
- Deleting AsCEP19 and AsCEP20 genes in A. solani led to abnormal conidial development, indicating these effectors influence fungal reproduction
- The deletion mutants of AsCEP19 and AsCEP20 showed significantly reduced virulence on potato and tomato plants, highlighting their essential role in the fungus's pathogenicity
