PCT No. PCT/NL96/00012 Sec. 371 Date Aug. 25, 1997 Sec. 102(e) Date Aug. 25, 1997 PCT Filed Jan. 8, 1996 PCT Pub. No. WO96/21023 PCT Pub. Date Jul. 11, 1996A DNA fragment is disclosed having a nucleotide sequence SEQ ID NO. 1 as shown in FIG. 4A or a homologous sequence having a similarity of at least 70% encoding 1-sucrose:sucrose fructosyltransferase. Another DNA fragment that is disclosed is a DNA fragment having a nucleotide sequence SEQ ID NO. 3 as shown in FIG. 4B or a homologous sequence having a similarity of at least 70% encoding 1-fructan:fructan fructosyltransferase. This invention also discloses a recombinant DNA comprising one or more of said DNA fragments, or comprising said DNA fragment(s) in the inverted orientation. Transformed organisms showing a modified fructan profile can be produced using said fragments.
