Function
Acts as a transcriptional activator. Binds to the GCC-box pathogenesis-related promoter element. Activates plants defense genes. Can confer resistance to Pseudomonas syringae tomato by potentiating the transcription of a set of pathogenesis related genes, downstream to a defense signaling pathway involving PTO and PRF, but probably independent of ethylene, jasmonate and salicylic acid.
