    摘要: PROBLEM TO BE SOLVED: To provide a method for improving the nutrient content of a plant, particularly of corn by decreasing the level of phytic acid and increasing the level of non-phytic acid phosphorus.SOLUTION: Methods are provided for producing newly identified polynucleotides and polypeptides in phytic acid biosynthetic pathways, variants and derivatives of the same, polynucleotides, polypeptides, variants, derivatives and antagonists. In particular, polynucleotides encoding inositol polyphosphate 2-kinase (IPP2-K) and polypeptides exhibiting such activity are provided to modulate the phytic acid biosynthesis in such a way as to decrease phytic acid and/or to increase non-phytic acid phosphorus, particularly in corn or soy animal feedstuff.
