Impact of plant type and plant induction on concentration of terpenoids in cotton. Terpenoid levels (μg/mg ± SE) in the youngest leaves collected from conventional cotton (Coker 312) and two ULGCS cotton lines (RNAi 1: 66-49B and RNAi 2: 66–274). A) Cotton plants were untreated. B) Cotton plants had been exposed to three 2nd instar S. littoralis. C) Cotton plants were treated with jasmonic acid (4.8 μmol). Within induction treatments, different letters over the same chemical compound indicate a significantly difference between plant types (upper case letter: hemigossypolone; upper case letter italics: heliocide H1 + H4; lower case letter: gossypol) (Tukey HSD test), n = 20–25
