Formation of a series ofmyo-inositol phosphates during growth of rice plant cells in suspension culture

摘要

A series ofmyo-inositol phosphates includingmyo-inositol mono- to hexa-phosphates was observed during growth of cultured rice plant cells. We also found that32Pi andmyo-[2-3H] inositol were incorporated into all thesemyo-inositol phosphates.myo-Inositol phosphorylating activity, which depended on ATP and Mg2+, was detected in the soluble fraction from the cells, and the reaction product was identified asmyo-inositol-2-phosphate.
