1 The maize low-phytic acid mutant lpa2 is caused by mutation in an inositol phosphate kinase gene. Phytic Acid inositol-tetrakisphosphate 1-kinase 1 Zea mays
2 Using a reverse genetics approach, we found that the maize (Zea mays) low-phytic acid lpa2 mutant is caused by mutation in an inositol phosphate kinase gene. Phytic Acid inositol-tetrakisphosphate 1-kinase 1 Zea mays
3 The ZmIpk mRNA is expressed in the embryo, the organ where phytic acid accumulates in maize seeds. Phytic Acid inositol-tetrakisphosphate 1-kinase 1 Zea mays
4 In the ZmIpk Mu insertion mutants, seed phytic acid content is reduced approximately 30%, and inorganic phosphate is increased about 3-fold. Phytic Acid inositol-tetrakisphosphate 1-kinase 1 Zea mays
5 These results provide evidence that ZmIpk is one of the kinases responsible for phytic acid biosynthesis in developing maize seeds. Phytic Acid inositol-tetrakisphosphate 1-kinase 1 Zea mays
