MAP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0682020 (HvMAP) on barley chromosome 7H encodes a Rab-GAP TBC domain-containing protein with GAP activity. The gene is associated with regulation of signal transduction, retrograde transport from endosome to Golgi, protein maturation, and secondary metabolism. Its product localises to the retromer complex, endosome membrane, Golgi complex, cytosol, cytoplasm, and nucleus. HvMAP is associated with auxin, shoot, meristem, and transcription factor. Studies of related genes in other species connect the family to grain length, grain size, grain yield, plant height, root dry weight, root number, water use efficiency, salinity tolerance, stripe rust, seed dormancy, germination rate, stomatal opening, leaf temperature, lignin content, proline content, photochemical quenching, and oxidative stress response.
