Functional Description ? help Back to Top
Source	Description
UniProt	Transcription repressor of phosphate (Pi) starvation-induced genes. Regulates negatively Pi starvation responses via the repression of gibberellic acid (GA) biosynthesis and signaling. Modulates root architecture, phosphatase activity, and Pi uptake and accumulation. {ECO:0000269\|PubMed:19529828}.

Regulation -- Description ? help Back to Top
Source	Description
UniProt	INDUCTION: Slightly induced by salicylic acid (PubMed:16463103). Induced reversibly in response to phosphate (Pi) deficiency but repressed in the presence of Pi, specifically in the leaves. Availability of Pi increases with decreased levels (PubMed:19529828). {ECO:0000269\|PubMed:16463103, ECO:0000269\|PubMed:19529828}.
