Jasmonic acid (JA) is an important hormonelike signaling molecule that is apparently distributed throughout the plant kingdom. It functions as an intermediate in defense response pathways against both pathogens and insects. JA was first identified as the methyl ester form (MeJA), which is a volatile fragrance component of jasmine and other flowers and fruits. As a naturally occurring plant chemical, JA might provide as more ecologically acceptable method of controlling microbial growth on plant food products, both before and after their harvest.
