Cis-Jasmone and lipopolysaccharides (LPS) mediate direct and indirect defense in corn

Plants under herbivore attack synthesize and emit mixtures of volatile organic compounds (VOCs) that directly repel herbivores and or indirectly attract natural enemies of herbivores. The role of Cis-jasmone and lipopolysaccharides (LPS) in interacting or repelling insect herbivores and their natural enemies has been reported.  However, the mechanism underlying these plant-insect interactions is not well understood. The hypothesis that exogenous application of Cis-Jasmone and LPS will elicit emission of corn VOCs was tested in this study.
