RT transporter4 mutants is dependent on the ammonium transporter 2 family

CC -!- FUNCTION: Involved in ammonium transport (By similarity). Required for
CC arbuscular mycorrhizal (AM) symbiosis with AM fungi (e.g. Glomus
CC versiforme and G.intraradices) in low nitrogen conditions
CC (PubMed:25841038). {ECO:0000250|UniProtKB:Q9M6N7,
CC ECO:0000269|PubMed:25841038}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:25841038};
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 (e.g. Glomus
CC versiforme). {ECO:0000269|PubMed:25841038}.
CC -!- TISSUE SPECIFICITY: Mostly expressed in mycorrhizal roots
CC (PubMed:25841038). Also observed in the cortex and endodermis of non-
CC mycorrhizal roots (PubMed:25841038). {ECO:0000269|PubMed:25841038}.
CC -!- DEVELOPMENTAL STAGE: Expressed in cortical cells containing arbuscules
CC of mycorrhizal roots upon arbuscular mycorrhizal (AM) symbiosis with AM
CC fungi (e.g. Glomus intraradices). {ECO:0000269|PubMed:25841038}.
CC -!- INDUCTION: Accumulates in roots during colonization by arbuscular
CC mycorrhizal (AM) fungi (e.g. Glomus versiforme).
CC {ECO:0000269|PubMed:25841038}.
CC -!- DISRUPTION PHENOTYPE: Normal arbuscular mycorrhizal (AM) symbiosis with
CC AM fungi (PubMed:25841038). Plants missing both PT4 and AMT2-3 fail to
CC establish AM symbiosis with AM fungi in high nitrogen conditions,
CC leading to premature arbuscule degeneration (PAD); these phenotypes are
CC not suppressed in nitrogen-deprived conditions (PubMed:25841038).
CC {ECO:0000269|PubMed:25841038}.
CC -!- SIMILARITY: Belongs to the ammonia transporter channel (TC 1.A.11.2)
CC family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=RHN41914.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=RHN41915.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
