Mutation of Inositol 1,3,4-trisphosphate 5/6-kinase6 Impairs Plant Growth and Phytic Acid Synthesis in Rice
Inositol 1,3,4-trisphosphate 5/6-kinase (ITPK) is encoded by six genes in rice (OsITPK1-6).A previous study had shown that nucleotide substitutions of OsITPK6 could significantly lower the phytic acid content in rice grains.In the present study, the possibility of establishing a genome editing-based method for breeding low-phytic acid cultivars in
