FT1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0663790 (FT1) on barley chromosome 7H encodes a protein of the XG_FTase family with alpha-1,2-fucosyltransferase activity, xyloglucan 6-xylosyltransferase activity, UDP-galactosyltransferase activity, and cellulose synthase activity. The protein localises to the Golgi membrane and endomembrane system. FT1 is associated with photoperiodism, floral organ development, pollen wall assembly, root hair development, cell wall biogenesis, xyloglucan and glycan biosynthesis, and regulation of cellular respiration. The gene has been linked to flowering time, anthesis time, daylength sensitivity, grain number, tiller number, plant height, leaf size, seed set, root morphology, aluminium response, salt tolerance, and disease tolerance. Studies of related genes in other species connect the family to xyloglucan fucosylation, arabinogalactan-protein glycosylation, and cell wall composition.
