Source	Description
UniProt	Transcription factor involved in phosphate starvation signaling (PubMed:11511543, PubMed:17927693, PubMed:26586833). Binds as a dimer to P1BS, an imperfect palindromic sequence 5'-GNATATNC-3', to promote the expression of inorganic phosphate (Pi) starvation-responsive genes (PubMed:11511543, PubMed:20838596, PubMed:26586833). SPX1 is a competitive inhibitor of this DNA-binding (PubMed:25271326). PHR1 binding to its targets is low Pi-dependent (PubMed:25271326). Regulates the expression of miR399 (PubMed:20838596). Regulates the expression of IPS1 (At3g09922), a non-coding RNA that mimics the target of miR399 to block the cleavage of PHO2 under Pi-deficient conditions (PubMed:17643101). Regulates lipid remodeling and triacylglycerol accumulation during phosphorus starvation (PubMed:25680792). Required for the shoot-specific hypoxic response (PubMed:24753539). Regulates FER1 expression upon phosphate starvation, linking iron and phosphate homeostasis (PubMed:23788639). Contributes to the homeostasis of both sulfate and phosphate in plants under phosphate deficiency (PubMed:21261953). Required for adaptation to high light and retaining functional photosynthesis during phosphate starvation (PubMed:21910737). Involved in the coregulation of Zn and Pi homeostasis (PubMed:24420568). {ECO:0000269\|PubMed:11511543, ECO:0000269\|PubMed:17643101, ECO:0000269\|PubMed:17927693, ECO:0000269\|PubMed:20838596, ECO:0000269\|PubMed:21261953, ECO:0000269\|PubMed:21910737, ECO:0000269\|PubMed:23788639, ECO:0000269\|PubMed:24420568, ECO:0000269\|PubMed:24753539, ECO:0000269\|PubMed:25271326, ECO:0000269\|PubMed:25680792, ECO:0000269\|PubMed:26586833}.
