METHOD FOR MODULATING THE LEVEL OF PHOSPHORYLATION OF STARCH IN A PLANT LINE, METHOD FOR SELECTING A PLANT OR PART THEREOF, INCLUDING A SEED AND TUBER, AND USE THEREOF

摘要

The invention relates to method for modulating the degree of phosphorylation of starch in plants by changing the allele composition of the alpha-glucan water dikinase (GWD) gene. A decrease in the amount (dosage) of the A allele and/or an increase in the amount (dosage) of the C and/or H allele infer an increase of phosphate content of the starch. The shifts in allele composition can be established by means of breeding, such as introgression, or by transgenic means, such as homologous recombination.
