MAP — Triticum turgidum subsp. durum

Summary

TRITD7AV1G097460 (symbol MAP, preferred name TtMAP) on durum wheat chromosome 7A encodes a Rab-GAP TBC domain-containing protein with 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. Associations with plant height and salt tolerance (SALTTL) have been noted. Studies of related genes in other species link the family to grain length, grain size, grain yield, seed dormancy, germination rate, salinity tolerance, stripe rust, water use efficiency, root dry weight, root number, leaf temperature, lignin content, proline content, stomatal opening, photochemical quenching, and oxidative stress response.
