Abstract A soluble extract from pea (Pisum sativum L.) roots, when incubated with ATP and inositol 1,4,5-trisphosphate, produced an inositol tetrakisphosphate. The chromatographic properties of this inositol tetrakisphosphate, and of the products formed by its chemical degradation, identify it as inositol 1,4,5,6-tetrakisphosphate. No evidence was obtained for a 3-phosphorylation of inositol 1,4,5-trisphosphate. The importance of these observations with respect to inositol phosphates and calcium signalling in higher plants, is discussed.
