Fructan formation in transgenic white clover expressing a fructosyltransferase from Streptococcus salivarius.

White clover (Trifolium repens L.) is an important pasture legume that does not normally accumulate fructan as a storage carbohydrate. We have generated transgenic white clover plants that accumulate fructan, by expressing the fructosyltransferase (Ftf) enzyme from the bacterium Streptococcus salivarius under the control of the cauliflower mosaic virus (CaMV) 35S promoter.
