PHO1 — Hordeum vulgare subsp. vulgare
Summary
HORVU.MOREX.R3.5HG0511800, designated HvPHO1 (also known as PHS1), encodes a protein with 1,4-alpha-oligoglucan phosphorylase activity (EC 2.4.1.1), pyridoxal phosphate binding, and transglycosidase activity, and belongs to the glycosyltransferase family 35. The gene is associated with starch breakdown and metabolism, glycogenolysis, phosphate homeostasis, seed development, programmed cell death, and response to thermal stimulus. Its product localises to the amyloplast, chloroplast stroma, plastid, and cytosol. HvPHO1 is linked to growth and shoot phenotypes, as well as reproductive period. Studies of related genes in other species connect the family to grain weight, yield, size, colour, starch content, seed dormancy and germination, sprouting tolerance, plant height, stem diameter, anthesis time, phosphorus uptake, and photochemical quenching.
