PHO1 — Hordeum vulgare subsp. vulgare
Summary
HORVU.MOREX.R3.6HG0627940 (HvPHO1) encodes a protein with SPX and EXS domains, annotated with phosphate transmembrane transporter activity, inositol hexakisphosphate (IP6) binding, ubiquitin-protein transferase activity, and protein binding. HvPHO1 is associated with phosphate ion transport, intracellular phosphate homeostasis, polyphosphate anabolism, and cellular response to phosphate starvation. It is also linked to regulation of seed and endosperm development, seed size, starch metabolism, red/far-red light signaling, cellular zinc ion homeostasis, and upregulation of cell size. The gene has been connected to traits including phosphorus uptake, flowering time, leaf senescence, low temperature stress response, and reproductive period. The encoded protein localizes to multiple cellular compartments including the plasma membrane, nucleus, endoplasmic reticulum, Golgi, endosomes, and mitochondria.
