Methyl salicylate is a critical mobile signal for plant systemic acquired resistance.

Science (New York, N.Y.) - 5 Oct 2007

Abstract excerpt

In plants, the mobile signal for systemic acquired resistance (SAR), an organism-wide state of enhanced defense to subsequent infections, has been elusive. By stimulating immune responses in mosaic tobacco plants created by grafting different genetic backgrounds, we showed that the methyl salicylate (MeSA) esterase activity of salicylic acid-binding protein 2 (SABP2), which converts MeSA into salicylic acid (SA),...
