The Influence Of Dose Of A Plant-Derived Volatile Cue On Arabidopsis Thaliana Resistance Against Insect Herbivores, Sarah Bissmeyer, Grace Freundlich, Christopher Frost

Kentucky Journal of Undergraduate Scholarship

Green leaf volatiles (GLVs) are plant-derived volatile organic compounds (VOCs) known to affect plant-plant communication. Specifically, GLVs can facilitate “priming”, whereby plants initiate a faster and stronger defensive response to a subsequent stress. The stress-induced GLV cis-3-hexenyl acetate (z3HAC) is a known priming cue, yet whether the concentration of the z3HAC affects plant defenses is unknown. Here, we tested the hypothesis that z3HAC concentration of would influence Arabidopsis thaliana resistance against a specialist (Trichoplusia ni) and generalist (Spodoptera exigua) herbivore. Our z3HAC treatments ranged from 0-100 ng/hr, which spanned the …
