| Abstract: | "Recent investigations showed that the model plant Arabidopsis thaliana specifically responds to herbivory-associated molecular patterns by activating a sophisticated signaling network. The lipase activity of insect oral secretions was shown to elevate oxylipin levels when applied to puncture wounds in leaves. The results also demonstrated that the oral secretions of the generalist Schistocerca gregaria contained other, probably non-proteinous, elicitors of plant defense responses which induced mitogen-activated protein kinases, calcium signaling and ethylene levels. This addendum presents data on the levels of additional phytohormones that are elevated after application of S. gregaria oral secretion to wounded leaves. Abscisic acid and salicylic acid levels are significantly elevated after elicitation with S. gregaria oral secretions, adding another layer of complexity to the herbivory-induced response of A. thaliana" |
