CC -!- FUNCTION: Low-affinity transporter for external inorganic phosphate
CC (Pi) probably involved in the acquisition of phosphate released by
CC arbuscular mycorrhizal (AM) fungi (e.g. Rhizophagus irregularis and
CC Glomus intraradices) during AM symbiosis (Probable). Acts as a Pi-
CC sensing machinery at the root tip level, independently of AM fungi,
CC involved in the regulation of early root branching and lateral roots
CC formation (By similarity). {ECO:0000250|UniProtKB:B5RHV8,
CC ECO:0000305|PubMed:18315538}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+)(in) + phosphate(in) = H(+)(out) + phosphate(out);
CC Xref=Rhea:RHEA:29939, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474;
CC Evidence={ECO:0000250|UniProtKB:Q8GSG4};
CC PhysiologicalDirection=right-to-left; Xref=Rhea:RHEA:29941;
CC Evidence={ECO:0000250|UniProtKB:Q8GSG4};
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q8GSG4};
CC Multi-pass membrane protein {ECO:0000255}. Note=Present on the
CC periarbuscular membrane in cells containing arbuscules during
CC arbuscular mycorrhizal (AM) symbiosis with AM fungi.
CC {ECO:0000250|UniProtKB:Q8GSG4}.
CC -!- INDUCTION: Regulated positively by RAM1 during arbuscular mycorrhiza
CC (AM) formation after inoculation with AM fungi (e.g. Rhizophagus
CC irregularis and Glomus intraradices). {ECO:0000269|PubMed:18315538,
CC ECO:0000269|PubMed:25971550}.
CC -!- MISCELLANEOUS: Although related to the sugar transporter family, it
CC does not transport sugars. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily.
CC Phosphate:H(+) symporter (TC 2.A.1.9) family. {ECO:0000305}.
