Fig. 3.

The levels of gossypol and related terpenoids in terminal buds, bracts, floral organs, bolls, and roots of transgenic progeny from RNAi lines are not reduced. The levels of terpenoids in various organs of wild-type control plants (red), T₁ transgenic progeny from RNAi line LCT66-2 (light green), and T₁ transgenic progeny from RNAi line LCT66-32 (dark green). The results shown are mean (±SEM) terpenoid values in tissue samples taken from three individual plants in each category. Note that in petals, gossypol was the only terpenoid detected and in the root tissue, the terpenoids detected were: gossypol (G), gossypol-6-methyl ether (MG), gossypol-6,6′-dimethyl ether (DMG), hemigossypol (HG), desoxyhemigossypol (dHG), hemigossypol-6-methyl ether (MHG), and desoxyhemigossypol-6,6′-methyl ether (dMHG).
