Costunolide production in planta.
LC-QTOF-MS analysis of non-volatiles metabolites from Nicotiana benthamiana leaves agro-infiltrated with empty vector, TcGAS, TcGAS+TcGAO, and TcGAS+TcGAO+TcCOS. The MS spectrum of the two new peaks (peak 22.21 and peak 22.66) in leaves agro-infiltrated with pyrethrum GAS+GAO+COS and their respective parent ions ([m/z]− 352.1613 and 538.2184, respectively) are shown.
