PHO1 — Solanum tuberosum
Summary
PGSC0003DMG400017163, designated PHO1 on potato chromosome 9, encodes a protein with an SPX domain and an EXS domain that exhibits inositol hexakisphosphate binding, phosphate transmembrane transporter activity, and ubiquitin-protein transferase activity. The gene is associated with phosphate ion transport, intracellular phosphate homeostasis, cellular response to phosphate starvation, and regulation of phosphate membrane transport. It has been linked to wound healing, as well as to phosphate content, phosphorus uptake, starch content, starch structure, leaf senescence, flowering time, and stomatal response to abscisic acid. Additional associations include shoot growth, root allometry, plant growth, and traits related to phosphorus utilization and acquisition. The protein localizes to the endomembrane system, plasma membrane, endoplasmic reticulum, Golgi complex, mitochondria, and nucleus.
