Phytic Acid 14-25 inositol-tetrakisphosphate 1-kinase 1 Zea mays 33-37 12586875-3 2003 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 74-85 inositol-tetrakisphosphate 1-kinase 1 Zea mays 86-90 12586875-6 2003 The ZmIpk mRNA is expressed in the embryo, the organ where phytic acid accumulates in maize seeds. Phytic Acid 59-70 inositol-tetrakisphosphate 1-kinase 1 Zea mays 4-9 12586875-8 2003 In the ZmIpk Mu insertion mutants, seed phytic acid content is reduced approximately 30%, and inorganic phosphate is increased about 3-fold. Phytic Acid 40-51 inositol-tetrakisphosphate 1-kinase 1 Zea mays 7-12 12586875-12 2003 These results provide evidence that ZmIpk is one of the kinases responsible for phytic acid biosynthesis in developing maize seeds. Phytic Acid 80-91 inositol-tetrakisphosphate 1-kinase 1 Zea mays 36-41
