| |
| - | <p align="justify">Plant resistance to biotrophic pathogens is classically thought to be mediated through SA signalling. Salicylic acid (SA), a phenolic phytohormone, is involved in many functions such as mediating in plant defence against pathogens. SA induces the production of pathogenesis-related (PR) proteins and is involved in the systemic acquired resistance (SAR), which is a "whole-plant" resistance response that occurs following an earlier localised exposure to a pathogen. SAR is analogous to the innate immune system found in animals. The resistance observed following induction of SAR is effective against a wide range of pathogens and the activation of SAR requires the accumulation of endogenous SA. SA modifications such as methylation and amino acid conjugation provide biological specificity in plant defence responses (Loake et al. 2007).

| |
| - | Methyl salicylate (MeSA), a volatile ester, is normally absent in plants but is dramatically induced upon pathogen infection. It acts as a mobile or volatile inducer of SAR by carrying this ‘under attack’ signal to neighbouring plants, following hydrolysis by methyl esterase in it’s immediate surrounding. MeSA is synthesised by SA carboxyl methyltransferase (SAMT).
