MAP — Oryza sativa Indica Group

Summary

BGIOSGA020742 (OiMAP, MAP) on chromosome 6 of Indica rice encodes a Rab-GAP TBC domain-containing protein with GTPase-activating protein (GAP) activity. The gene is associated with the retromer complex, endosome membrane, Golgi complex, cytoplasm, and nucleus, and is linked to retrograde transport from endosome to Golgi, the MAPK cascade, cell division, and salinity response. In this species, OiMAP has been connected to root number, grain length, grain size, and salinity tolerance. Studies of related genes in other species link the family to traits including leaf temperature, root dry weight, water use efficiency, stripe rust, seed dormancy, germination rate, plant height, grain yield, and oxidative stress response.
