FT1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.4HG0358820 (HvFT1) on barley chromosome 4H encodes a xyloglucan fucosyltransferase (XG_FTase) with alpha-1,2-fucosyltransferase, xyloglucan 6-xylosyltransferase, and UDP-galactosyltransferase activities. The protein localises to the Golgi membrane and endomembrane system. HvFT1 is associated with photoperiodism, floral organ development, pollen wall assembly, root hair elongation, and cell wall biogenesis. It has been linked to flowering time, daylength sensitivity, grain number, tiller number, plant height, leaf size, root system morphology, seed set, disease tolerance, and salt tolerance. Studies of related genes in other species connect the family to arabinogalactan-protein fucosylation and cell wall composition, and to heading time, spikelet number, and grain yield.
