MODULATING THE CONTENT OF REDUCING SUGAR IS ONE PLANT

Are disclosed in the present description an plant cell which comprising: (i) one that polynucleotide comprising， that consists or consists essentially in that sequence which has one to the Less one of identity of 95 % with the sequence SEQ ID no: 1 or SEQ ID no: 3 or the the SEQ ID no: 9 or SEQ ID no: 11 or the the SEQ ID no: 17 or SEQ ID no: 19 or the the SEQ ID no: 21 or SEQ ID no: 23 the; Or one which polynucleotide comprising， that consists or consists essentially in that sequence that one has to the less one of identity of 80 % with the sequence SEQ ID No 5 or the SEQ ID no: 7 or SEQ ID no: 13 or the the SEQ ID no: 15; (ii) one polypeptide encoded by the polynucleotide is exposed (i); (iii) one polypeptide that comprising， That consists or consists essentially in that sequence that one has to the less one of identity of 94 % with the sequence SEQ ID no: 2; or to the less 93 % of Of identity with the sequence SEQ ID no: 4; or to the less of identity of 95 % with the sequence SEQ ID no: 6; or to the less of identity of 96 % with the sequence SEQ ID no: 8; Or less to the of 93 % of identity with the sequence SEQ ID no: 10 or the SEQ ID no: 12; or to the less of identity of 95 % with the sequence SEQ ID no: 14; or to the less 96 % of Of identity with the sequence SEQ ID no: 16; or to the less of identity of 89 % with the sequence SEQ ID no: 18; or to the less of identity of 92 % with the sequence SEQ ID no: 20; Or less to the of 93 % of identity with the sequence SEQ ID no: 22; or to the less of identity of 94 % with the sequence SEQ ID no: 24; or (iv) one construct， or vector of expression vector comprising the isolated polynucleotide that is exposed (i)， where said cell is Plant comprising less one to the modification that modulates expression or activity of the polynucleotide or the polypeptide in comparison with one control plant cell in which the expression or activity of the polynucleotide or the polypeptide are not been modified.
