Research Abstract |
NPR1 protein is the key transcription coactivator in salicylic acid (SA) signaling. Although the formation of NPR1 oligomer is prerequisite for its activation, the molecular mechanism is not fully elucidated. Here we have identified EF-Tu as a member of NPR1 complex in planta. We found that EF-Tu is involved in the stabilization of NPR1 oligomer, and disease resistance against Pseudomonas syringae. It is strongly suggested that EF-Tu is a positive regulator of SA-mediated signaling.
