Until recently jasmonic acid (JA) and its fragrant methyl ester, methyl jasmonate (MeJA), had been studied only modestly since their discovery in plants over 30 years ago. Early research focused primarily on their potential role in plant growth and development. However, after jasmonate was shown to increase the expression of genes involved in plant defense, there was a surge in activity aimed at clarifying the function of these potentially important signaling molecules. Although considerable work remains, increasing evidence supports the hypothesis that jasmonate is involved in signaling stress responses in plants.
