Phosphate transporter PHO1; Inositol polyphosphate sensor that associates with transcription factors to regulate inorganic phosphate (Pi) starvation responses. Probably acts by binding inositol polyphosphate via its SPX domain. Acts as a Pi exporter, mediating efflux of Pi out of cells. Transfers Pi from the epidermal and cortical cells to the root xylem vessels. Involved in the transfer of Pi from roots to shoots. Involved in abscisic acid (ABA) induction of stomatal closure and ABA repression of stomatal opening. Belongs to the SYG1 (TC 2.A.94) family.

Protein PHOSPHATE STARVATION RESPONSE 1; Transcription factor involved in phosphate starvation signaling. Binds as a dimer to P1BS, an imperfect palindromic sequence 5'-GNATATNC-3', to promote the expression of inorganic phosphate (Pi) starvation- responsive genes. SPX1 is a competitive inhibitor of this DNA-binding. PHR1 binding to its targets is low Pi-dependent. Regulates the expression of miR399. 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. Regulates lipid remodeling and [...]

E3 SUMO-protein ligase SIZ1; E3 SUMO protein ligase involved in regulation processes. Mediates SUMO/ attachment to PHR1, a MYB transcriptional activator controlling the phosphate deficiency responses. Functions as an upstream negative regulator of salicylic acid (SA) accumulation and subsequent SA-mediated systemic acquired resistance (SAR) signaling. Probably not involved in jasmonic acid (JA)-mediated defense response. Participates in abiotic stress-induced sumoylation. Controls heat shock-induced SUMO1 and SUMO2 conjugation and facilitates basal thermotolerance. Involved in freezing [...]
