MAP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0739270, designated HvMAP on barley chromosome 7H, encodes a protein with a Rab-GAP TBC domain and GTPase-activating protein (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 agronomically important traits including grain length and size, grain yield, plant height, root dry weight and number, water use efficiency, salinity tolerance, stripe rust resistance, seed dormancy and germination, leaf temperature, lignin and proline content, stomatal opening, and oxidative stress response.
