7.3.2.1 ABC-type phosphate transporterIUBMB Comments
An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the high affinity uptake of phosphate anions. Unlike P-type ATPases, it does not undergo phosphorylation during the transport process.

upon phosphate starvation, these low-affinity phosphate transporters, e.g. Pho87 and Pho90, are endocytosed and targeted to the vacuole. For Pho87, this process strictly depends on SPL2, another Pho4-dependent gene that encodes a protein known to interact with the N-terminal SPX domain of the transporter. In contrast, the vacuolar targeting of Pho90 upon phosphate starvation is independent of both Pho4 and Spl2, although it still requires its SPX domain. Both Pho87 and Pho90 are also targeted to the vacuole upon carbon-source starvation or upon treatment with rapamycin, which mimics nitrogen starvation, responses are independent of PHO pathway signalling requiring only the transporter N-terminal SPX domain. Spl2 mediates phosphate-starvation-induced vacuolar targeting of Pho87, but not of Pho90

Pht1;5-defective mutants show reduced phosphate allocation to shoots and elevated transcript levels for several phosphate starvation-response genes under low-phosphate conditions, under phosphate-replete conditions, pht1;5-1 has higher shoot phosphate content compared to the wild-type but has reduced phosphate content in roots. Overexpression of Pht1;5 affects the distribution and remobilization of phosphate between source and sink. Constitutive overexpression of Pht1;5 has the opposite effect on phosphate distribution: namely, lower phosphate levels in shoots and higher phosphate content in roots compared to the wild-type. Pht1;5 overexpression also results in altered phosphate remobilization, as evidenced by a greater than 2fold increase in the accumulation of phosphate in siliques, premature senescence, and an increase in transcript levels of genes involved in phosphate scavenging. Furthermore, Pht1;5 overexpressors exhibit increased root hair formation and reduced primary root growth that could be rescued by the application of silver nitrate, an ethylene perception inhibitor, or aminoethoxyvinylglycine, an ethylene biosynthesis inhibitor, respectively. Ethylene signaling in modulating the primary root and root hair phenotypes of Pht1;5 overexpression lines, overview

phosphate transporter mechanism in the plant cell, overview. When the supply of phosphate is limited, plants grow more roots, increase the rate of phosphate uptake by roots from soil solution, retranslocate phosphate from older leaves, and deplete the vacuolar stores of phosphate. There is also significant retranslocation of phosphate in the phloem from older leaves to the growing shoot and from the shoot to the root

the enzyme is involved in arbuscular mycorrhizal, AM, symbiosis,. During arbuscular mycorrhizal symbiosis, the AM fungus colonizes the root cortical cells where it forms branched hyphae called arbuscules that function in nutrient exchange with the plant. Each arbuscule is enveloped in a plant membrane, the periarbuscular membrane, that contains a unique set of proteins including phosphate transporters such as MtPT4 that are essential for symbiotic phosphate transport
metabolism
-
upon phosphate starvation, these low-affinity phosphate transporters, e.g. Pho87 and Pho90, are endocytosed and targeted to the vacuole. For Pho87, this process strictly depends on SPL2, another Pho4-dependent gene that encodes a protein known to interact with the N-terminal SPX domain of the transporter

LITERATURE
1.3 kb promoter of TaPHT1.2 contains a number of phosphate-starvation responsive elements, including P1BS, WRKY-binding W-box, and helix-loop-helix-binding elements. Reporter gene expression analysis using this 1.3 kb promoter of TaPHT1.2 shows that the reporter gene is specifically induced by Pi-starvation and predominantly expressed in the roots
-
circadian expression of phosphate transporter gene pht4;1 is dependent on the protein circadian clock associated 1
-
enzyme expression is triggered in phosphate-starved mycorrhizal roots
expression of isoform PT13 is induced by 0.01 and 0.1 mM As(V) treatment, while isoforms PT5 and PT10 are induced only by 0.1 mM As(V)
-
in gametophytes, Pht1;3 transcript levels increase in response to phosphate deficiency and arsenate exposure
-
in roots, expression of isoform PT2 and PT3 is strongly inhibited by 0.01 and 0.1 mM As(V) treatment
-
OsPT1 expression is strongly enhanced by mutation of phosphate over-accumulator 2, OsPHO2, but not by phosphate starvation response 2, OsPHR2. OsPT8 and OsPT4 are significantly and moderately upregulated, respectively, in OsPT1 overexpressing plants
-
PHO84, encoding the high-affinity H+/phosphate symporter, expression is activated by the Pho4 transcription factor in phosphate-starved cells as part of the PHO signalling pathway
Pht1;9 is induced by phosphate starvation
the Pht1;4 induction by phosphate deficiency is dependent on the existence of sugar
-
transcription of PHO87 and PHO90, encoding the low-affinity H+/phosphate transport system, is independent of phosphate status
PHO84, encoding the high-affinity H+/phosphate symporter, expression is activated by the Pho4 transcription factor in phosphate-starved cells as part of the PHO signalling pathway
