Accumulation of phenylacetic acid, L-aspartic acid, and L-asparagine in herbivore-damaged and undamaged Populus trichocarpa leaves. Methanol extracts made from L. dispar-damaged leaves (herb) and undamaged control leaves (ctr) were analyzed via LC-MS/MS. Means and SE are shown (n = 10 biological replicates). Phenylacetic acid, p = 0.066; Asp, p = 0.247; Asn, p = 0.121. DW, dry weight; FW, fresh weight
