ITPK1 is an InsP <sub>6</sub> /ADP phosphotransferase that controls systemic phosphate homeostasis in Arabidopsis

2020-05-19

Abstract excerpt

<h4>ABSTRACT</h4> In plants, phosphate (P i ) homeostasis is regulated by the interaction of P i starvation response transcription factors (PHRs) with stand-alone SPX proteins, which act as sensors for inositol pyrophosphates (PP-InsPs). Recently, ITPK1 was shown to generate the PP-InsP InsP 7 from InsP 6 in vitro , but the importance of this activity in P i signaling remained unknown. Here, we show that unc...
