MAP — Triticum turgidum subsp. durum

Summary

TRITD7BV1G206120, designated TtMAP on durum wheat chromosome 7B, encodes a Rab-GAP TBC domain-containing protein with 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 is associated with plant height and SALTTL, as well as auxin, shoot, meristem, and transcription factor. 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.
