PHO1 — Triticum aestivum
Summary
TRAESCS5A02G395200, designated TaPHO1 (also known as TaPHS1-5A) on bread wheat chromosome 5A, encodes a glycogen phosphorylase (EC 2.4.1.1) with 1,4-alpha-oligoglucan phosphorylase activity and pyridoxal phosphate binding. The product localises to amyloplasts, plastids, chloroplast stroma, and cytosol. TaPHO1 is associated with pre-harvest sprouting, seed dormancy, seed germination, starch metabolism, and grain yield. It is linked to grain color, starch content, seed viability, anthesis time, reproductive period, and sprouting tolerance. The gene is associated with growth, plant growth, and shoot phenotypes, as well as response to thermal stimulus and response to thirst. Studies of related genes in other species connect the family to starch biosynthesis, endosperm development, phosphorus homeostasis, and grain weight.
