GILT — Oryza sativa Indica Group

Summary

BGIOSGA004729 (GILT, OiGILT) on chromosome 1 of Indica rice encodes a protein with oxidoreductase activity acting on a sulfur group of donors with disulfide as acceptor, belonging to the interferon-induced GILT domain family and possessing redox activity. The gene is associated with heterosis, grain number, and grain yield, as well as sulfur deficiency-responsive gene expression and O-acetyl-L-serine accumulation. Its product localizes to secretory vesicles, plant-type vacuoles, and the extracellular space. Studies of related genes in other species link the GILT family to a wide range of traits including grain size, weight, shape, seed dormancy, germination, viability, plant height, panicle number, culm number, leaf angle, stem elongation, inflorescence branching, floral organ number, plastochron, rachis length, anthesis time, and tolerance to submergence, salinity, and cold.
