Hypothetical model for the possible involvement of ononitol in the accumulation of stachyose and sucrose in IMT transgenic canola. (A) Hypothetical production of stachyose and ononitol via galactosylononitol in B. napus; (B) Hypothetical production of stachyose and sucrose via raffinose:raffinose galactosyltransferase in B. napus. Dotted arrows indicate reduced biosynthesis. Dashed arrows indicate possible alternate routes. Dash-dotted arrows indicate probable direct galactosyl-residue transfer from raffinose. On, ononitol; Ins, myo-inositol; IMT, myo-inositol methyltransferase; UDP-gal, uridine diphosphate galactose.
