ERF and infection: The most abundant clone rescued from the Pa bio-panning encoded for the defence-related protein ATERF-1 (At4g17500), a member of the AP2/ERF-family of transcription factors which is highly induced upon infection with different pathogens [30]–[32]; the ATERF-1 fusion to T7-10B (amino acids 176 to 268) comprises the DNA-binding and defence-related domains.
