Development of SAR requires the translocation of one or more mobile signals from the site of infection through the vascular system to distal (systemic) tissues. MeSA esterase activity is required in distal, healthy tissue of pathogen-infected plants to hydrolyze MeSA, which functions as a long-distance, phloem-mobile SAR signal; this hydrolysis releases the biologically active. The difference in structures between methyl salicylate and salicylic acid is a single functional group. Start studying CHEM-CH 14 HW. That leaves C.
