Previously, we identified a soluble salicylic acid (SA)-binding protein (SABP) in tobacco whose properties suggest that it may play a role in transmitting the SA signal during plant defense responses. This SA-binding activity has been purified 250-fold by conventional chromatography and was found to copurify with a 280-kDa protein. Monoclonal antibodies capable of immunoprecipitating the SA-binding activity also immunoprecipitated the 280-kDa protein, indicating that it was responsible for… CONTINUE READING
