PHO1 — Triticum aestivum

Summary

TRAESCS5B02G400000, symbol TaPHO1 (also known as TaPHS1), encodes a protein with 1,4-alpha-oligoglucan phosphorylase activity, glycogen phosphorylase activity, transglycosidase activity, identical protein binding, and pyridoxal phosphate binding, and localizes to the amyloplast, plastid, chloroplast stroma, cytosol, and cytoplasm. The gene is associated with pre-harvest sprouting, seed dormancy, seed germination, starch metabolism and content, grain yield, grain color, anthesis time, reproductive period, and sprouting tolerance. It has also been linked to glycogenolysis, Pi homeostasis, meiosis, response to thermal stimulus, and plant growth. Studies of related genes in other species link the family to starch biosynthesis in the endosperm and seed, and to Pi homeostasis.
