MAP — Oryza sativa Indica Group

Summary

BGIOSGA029008 (OiMAP, MAP) on chromosome 8 of Indica rice encodes a Rab-GAP TBC domain-containing protein with GAP activity. The gene is associated with the MAPK cascade, retrograde transport from endosome to Golgi, and cell division. It localises to the retromer complex, endosome membrane, Golgi complex, cytoplasm and nucleus. OiMAP is linked to grain length, grain size, root number and salinity tolerance. Related genes in other species connect the family to additional traits such as plant height, grain yield, seed dormancy, germination rate, water use efficiency, leaf temperature, root dry weight, lignin content, proline content, stomatal opening, photochemical quenching, oxidative stress response and stripe rust resistance.
