Priming defense genes and metabolites in hybrid poplar by the green leaf volatile cis-3-hexenyl acetate

ABSTRACT: • Herbivore-induced plant volatiles (HIPVs), in addition to attracting natural enemies of herbivores, can serve a signaling function within plants by acting as wound signals that induce or prime defenses. However, particularly in woody plants, which compounds within HIPV blends are capable of acting as signaling molecules are largely unknown. • Leaves of hybrid poplar (Populus deltoides x nigra) saplings were exposed in vivo to naturally wound-emitted concentrations of the green leaf volatile (GLV) cis-3-hexenyl acetate (z3HAC) and then subsequently fed upon by gypsy moth larvae (Lymantria dispar L.). Volatiles were collected throughout the experiments, and leaf tissue was collected to measure phytohormone levels and expression of defense-related genes. • Relative to controls, z
