PHO1 — Solanum tuberosum

Summary

PGSC0003DMG400025127, designated StPHO1 on potato chromosome 5, encodes a protein with SPX, EXS and Znf_DNL-type domains that exhibits phosphate transmembrane transporter activity, inositol hexakisphosphate (IP6) binding, ubiquitin-protein transferase activity, zinc binding and protein binding. The gene is associated with phosphate ion transport, intracellular phosphate homeostasis, regulation of phosphate membrane transport, cellular response to phosphate starvation, polyphosphate and starch anabolism, sucrose breakdown, glutathione metabolism, fatty acid anabolism, nitric oxide storage and signal transduction. It is linked to wound healing, phosphate content, phosphorus uptake, starch content and structure, low temperature stress response, leaf senescence, flowering time, phosphate starvation response, phosphate deficiency response, phosphate transport, phosphate translocation, stomatal response to abscisic acid, phosphate acquisition, shoot phosphate content, shoot growth, phosphate uptake, inorganic phosphate uptake, phosphate efflux, root allometry, plant growth, phosphate export, phosphorus utilization, and reduced growth and impaired root-to-shoot phosphate transfer. The protein localises to the plasma membrane, endoplasmic reticulum, Golgi, trans-Golgi network, mitochondria, nucleus and protoplasm.
