DNA SEQUENCES ENCODING CARBOHYDRATE POLYMER SYNTHESIZING ENZYMES AND METHOD FOR PRODUCING TRANSGENIC PLANTS

摘要

A DNA fragment is disclosed having a nucleotide sequence SEQ ID No. 1 as shown in Figure 4A or a homologous sequence having a similarity of at least 70 % encoding 1-sucrose:sucrose fructosyltransferase. Also disclosed is a DNA fragment having a nucleotide sequence SEQ ID No. 2 as shown in Figure 4B or a homologous sequence having a similarity of at least 70 % encoding 1-fructan:fructan fructosyltransferase. Further this invention discloses a recombinant DNA comprising one or more of said DNA fragments, or comprising said DNA fragment(s) in the inverted orientation. Using said fragments transformed organisms can be produced showing a modified fructant profile.
