ITPK1 is an InsP6/ADP phosphotransferase that controls systemic phosphate homeostasis in Arabidopsis

E. Riemer, D. Laha, R. K. Harmel, P. Gaugler, V. Pries, M. Frei, M. R. Hajirezaei, N. P. Laha, L. Krusenbaum, R. Schneider, H. J. Jessen, A. Saiardi, D. Fiedler, G. Schaaf, R. F. H. Giehl

This study shows ITPK1 generates PP-InsPs from InsP6 and regulates phosphate homeostasis in Arabidopsis by controlling InsP7 and InsP8 synthesis.

Inositol pyrophosphates promote the interaction of SPX domains with the coiled-coil motif of PHR transcription factors to regulate plant phosphate homeostasis.

M. K. Ried, R. Wild, J. Zhu, L. Broger, R. K. Harmel, L. A. Hothorn, D. Fiedler, M. Hothorn

The paper shows that InsP8 binds to SPX domains, altering PHR transcription factors' oligomeric state and DNA binding, thus regulating phosphate homeostasis in plants.

Two bifunctional inositol pyrophosphate kinases/phosphatases control plant phosphate homeostasis.

J. Zhu, K. Lau, R. K. Harmel, R. Puschmann, L. Broger, A. K. Dutta, H. J. Jessen, L. A. Hothorn, D. Fiedler, M. Hothorn

This study identifies VIH1 and VIH2 as bifunctional enzymes regulating phosphate homeostasis in Arabidopsis by modulating PP-InsP levels in response to ATP concentration changes.
