Protein

Inorganic phosphate transporter 1-4

Gene

PHT1-4

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

High-affinity transporter for external inorganic phosphate. Acts as a H+:phosphate symporter in both low- and high-Pi conditions. Confers sensitivity to arsenate.3 Publications

Miscellaneous

Although related to the sugar transporter family, it does not transport sugars.

Expressioni

Tissue specificityi

Mostly expressed in roots, in tissues connecting the lateral roots to the primary root. Also present in flowers, in senescing anther filaments and in the abscission zone at the base of siliques. Expressed in hydathodes and axillary buds, and in some senescing leaves. After Pi starvation, localized in all cells of undifferentiated root segments, including root tips and root hairs, and in the epidermis, cortex and stellar regions of mature root segments.5 Publications

Inductioni

In roots by phosphate starvation. Repressed by the Pi analog phosphite (Phi).6 Publications
