We previously reported the identification of 29 putative substrates of Mitogen-activated Protein Kinase3 (AtMPK3), AtMPK4 and AtMPK6, based on a solid-phase phosphorylation screening using a lambda phage expression library in Arabidopsis thaliana. In this study, a putative MPK substrate, AtERF72 (At3g16770), was strongly phosphorylated by AtMPK6 on the serine residue at position 151 (Ser151). AtERF72 binds to the GCC box (AGCCGCC) in the promoters of several pathogenesis-related (PR) genes and activates their transcription. We also show that the DNA-binding activity of AtERF72 is enhanced upon phosphorylation by AtMPK6 in vitro. In addition, transient co-expression experiments in Arabidopsis protoplasts revealed that effector constructs expressing a mutant variant of AtERF72, AtERF72S151D (carrying a Ser to aspartic acid [Asp] substitution at amino acid position 151) showed higher expression of the β-glucuronidase (GUS) reporter gene driven by the GCC box element than effector constructs expressing the wild-type AtERF72. Furthermore, yeast two-hybrid assays revealed that the interaction between AtERF72S151D and TGA4/OBF4 was stronger than that between wild-type AtERF72 and TGA4/OBF4. Since AtERF72S151D is equivalent to AtERF72 phosphorylated by AtMPK6 at Ser151, these results suggest that the phosphorylation of AtERF72 by AtMPK6 triggers an event of transcriptional regulation from defence signalling in Arabidopsis."xsd:string |
