MAP — Triticum turgidum subsp. durum

Summary

TRITD7AV1G256140, designated TtMAP on durum wheat chromosome 7A, encodes a protein with a Rab-GAP TBC domain and GTPase-activating protein (GAP) activity. The gene is associated with retrograde transport from endosome to Golgi, the HOG response, protein phosphorylation, and cell death. Its product localises to the retromer complex, endosome membrane, Golgi complex, cytoplasm, and nucleus. TtMAP has been linked to plant height and salt tolerance. Studies of related genes in other species connect the family to grain length, grain size, grain yield, seed dormancy, germination rate, root dry weight, root number, water use efficiency, salinity tolerance, stripe rust, leaf temperature, lignin content, proline content, stomatal opening, photochemical quenching, and oxidative stress response.
