MAP — Brachypodium distachyon

Summary

BdMAP (BRADI_3G40590V3) on chromosome 3 of Brachypodium distachyon 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, stomatal closure, ribosome biogenesis, and signal transduction. Its product localises to the retromer complex, endosome membrane, Golgi complex, cytosol, cytoplasm, and nucleus. BdMAP has been linked to water use efficiency and oxidative stress response. Studies of related genes in other species connect the family to traits including grain length, grain size, grain yield, plant height, root dry weight, root number, leaf temperature, lignin content, proline content, salinity tolerance, stripe rust, germination rate, seed dormancy, stomatal opening, and photochemical quenching.
