To characterize the role of the phytotoxin mimic 6-substituted indanoyl isoleucine conju- gate1in plant secondary metabolism, tobacco (Nicotiana tabacumL. K326) was treated with compound1. The volatile compounds of tobacco leaves were analyzed by GC-MS. In contrast to the control, three compounds, farnesene (2), santalol (3) and tetradecanal (4), were in- duced by treatment with 1 mmof compound1. Concurrently other volatile compounds were also regulated.
