FT1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0617710 (HvFT1) on barley chromosome 6H encodes a xyloglucan fucosyltransferase (XG_FTase family) 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 is linked to flowering time, daylength sensitivity, grain number, tiller number, plant height, anthesis time, leaf size, stem elongation, root system morphology, seed set, and disease tolerance. Additional associations include salt tolerance, aluminium response, stomatal opening, and leaf senescence. Studies of related genes in other species link the fucosyltransferase family to cell wall composition, xyloglucan fucosylation, and arabinogalactan protein glycosylation.
