Comparison of volatiles from Anoplophora glabripennis (Motsch.) and methyl jasmonate (MeJA)-applied Acer mono Maxim to identify wound signal transduction pathways

Given that the behaviors of Anoplophora glabripennis (Motsch.) and methyl jasmonate (MeJA)-applied Acer mono Maxim were similar in their damage of Acer mono Maxim we asked whether the volatiles from the plants after two treatments would be similar. To find out, compounds in the profiles of volatiles from the species were identified and quantified by GC-MS equipped with a CP-4020 TCT device; and nine volatiles that were not found in the undamaged plant (acetic acid butyl ester, ethyl acetate, 2-Nonanol, hexanol, trans-2-hexenol, ethylhexanol, 1-Octene, caryophyllene and farnesene) were induced. Terpenes, aldehydes and alcohols were also induced or their relative concentrations increased. The results of the effect of the two treatments on the temporal variation of the volatiles showed some compounds such as 3-hexenyl acetate, acetic acid butyl ester, 1-hexanol, (Z)-3-hexenol, ocimene and farnesene were similar too. We concluded that jasmonic acid (JA) was involved in the signal transduction of the defense pathway induced by the feeding damage of Anoplophora glabripennis.
