PHO1 — Triticum aestivum
Summary
TRAESCS5D02G404500 (TaPHO1, also known as TaPHS1) on wheat chromosome 5D encodes a 1,4-alpha-oligoglucan phosphorylase (glycogen phosphorylase) with pyridoxal phosphate binding and transglycosidase activity. The gene is associated with pre-harvest sprouting, seed dormancy, seed germination, and sprouting tolerance, as well as starch metabolism, glycogenolysis, and Pi homeostasis. It has been linked to grain yield, grain color, starch content, seed viability, anthesis time, and reproductive period. The product localizes to the amyloplast, plastid, chloroplast stroma, and cytosol. Studies of related genes in other species connect the family to starch biosynthesis, endosperm development, phosphorus uptake, grain weight, plant height, and stem diameter.
