PHO1 — Oryza sativa Japonica
Summary
OsPHO1 (OS01G0110100) on rice chromosome 1 encodes a protein containing SPX and EXS domains with phosphate transmembrane transporter activity, IP6 binding, and ubiquitin-protein transferase activity. The gene is associated with regulation of phosphate membrane transport, intracellular Pi homeostasis, and cellular response to phosphate starvation. It is linked to seed development and endosperm development, regulation of seed size, starch metabolism, and grain yield. Additional associations include panicle length, flowering time, leaf senescence, low temperature stress response, and reproductive period. The protein localizes to multiple cellular compartments including the plasma membrane, nucleus, endoplasmic reticulum, Golgi, and mitochondria. Related genes in other species are linked to phosphate loading to xylem and arsenic accumulation.
