MAP — Oryza sativa Japonica

Summary

Rice gene OS08G0518100, designated MAP on chromosome 8, encodes a protein with a Rab-GAP TBC domain and GAP activity. The gene is associated with ferroptosis, invasive growth, appressorium formation, anther development, response to hydrogen peroxide and salt stress, MAPK cascade, cell cycle modulation, cell wall organization, embryogenesis, and regulation of gene expression. It localizes to the retromer complex, endosome membrane, Golgi complex, cytoplasm, and nucleus. MAP is linked to salinity tolerance and grain yield. Studies of related genes in other species connect the family to additional traits such as grain length, grain size, plant height, root dry weight, water use efficiency, seed dormancy, germination rate, and responses to oxidative stress and stripe rust.
