GILT — Oryza sativa Indica Group

Summary

BGIOSGA010926 (GILT, OiGILT) on Indica rice chromosome 3 encodes a protein with an interferon-induced GILT domain and oxidoreductase activity acting on a sulfur group of donors with disulfide as acceptor, along with redox activity. The gene is associated with heterosis, grain number, and grain yield, as well as with sulfur deficiency-responsive gene expression and O-acetyl-L-serine accumulation. Its product localises to secretory vesicles, the plant-type vacuole, and the extracellular space. Studies of related genes in other species link the GILT family to a wide range of traits including grain size, grain weight, seed dormancy, seed viability, submergence tolerance, salinity tolerance, cold tolerance, plant height, panicle number, culm number, leaf angle, stem elongation, inflorescence branching, floral organ number, meristem identity, plastochron, rachis length, and anthesis time.
