FT1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0617730 (HvFT1) on barley chromosome 6H encodes a protein of the XG_FTase family with alpha-1,2-fucosyltransferase activity, xyloglucan 6-xylosyltransferase activity, fucosyltransferase activity, UDP-galactosyltransferase activity, cellulose synthase activity, UDP-xylosyltransferase activity, hexosyltransferase activity, transglycosidase activity, sugar binding, protein homodimerization activity, and protein binding. The protein localizes to the Golgi membrane and endomembrane system. HvFT1 is associated with photoperiodism, floral organ development, pollen wall assembly, root hair elongation, cell wall biogenesis, regulation of cellular respiration, protein O-linked glycosylation, fucose anabolism, arabinogalactan protein metabolism, cellular respiration, xyloglucan anabolism, endomembrane organization, glycan biosynthesis, pollen tube development, root hair cell development, and glycoprotein anabolism. It is linked to flowering time, anthesis time, daylength sensitivity, grain number, tiller number, plant height, leaf size, root system morphology, seed set, aluminum response, salt tolerance, disease tolerance, and other traits. Studies of related genes in other species link the family to xyloglucan fucosylation, cell wall composition, and arabinogalactan protein glycosylation.
