PHO1 — Oryza sativa Japonica
Summary
Os06g0493600, designated PHO1 in rice (Oryza sativa Japonica) on chromosome 6, encodes a protein containing SPX and EXS domains and is associated with phosphate transmembrane transporter activity, IP6 binding, ubiquitin-protein transferase activity, and protein binding. The gene is linked to the regulation of phosphate membrane transport, intracellular Pi homeostasis, polyphosphate anabolism, and cellular zinc ion homeostasis. It is associated with seed development and size regulation, endosperm development, starch metabolism, and the red/far-red light signaling pathway. Associations also include grain yield, panicle length, phosphorus uptake, flowering time, leaf senescence, low temperature stress response, and reproductive period. The protein localizes to the nucleus, cytosol, plasmalemma, endoplasmic reticulum, Golgi, endosome, and mitochondria. Related genes in other species are linked to phosphate loading to xylem and arsenic accumulation.
