Model for role of PAP5 during Pst DC3000 infection. When plants are infected with virulent Pst DC3000, PAP5 is required for activation of defense responsive genes including PR1 and ICS1. Recognition of Pst DC3000, induce expression of PAP5 only during the early stages of infection (6 h) and triggers ROS synthesis which subsequently activates other defense related signals down stream for complete resistance.
