Apoplastic peroxidases are required for salicylic acid-mediated defense against Pseudomonas syringae

[Display omitted] •Arabidopsis plants deficient in expression of peroxidases are impaired in salicylic acid signaling.•NPR1, a key regulator of SA-mediated responses, fails to monomerize in peroxidase deficient plants.•Peroxidase deficient plants exhibit defects in some but not all aspects of patter...
