GILT — Oryza sativa Japonica

Summary

OsGILT (OS03G0295800) in rice encodes a protein with a gamma-interferon-inducible lysosomal thiol reductase (GILT) domain and redox activity. This gene is associated with meristem development, maintenance, initiation, and determinacy, periclinal cell division, shoot regeneration, floral meristem determinacy, integument development, hormone metabolism, gibberellin and auxin biosynthesis, phytoalexin biosynthesis, nuclear import, and hypersensitivity. Associations with traits include culm number, panicle number, grain number, grain weight, grain size, grain shape, seed weight, seed dormancy, plant height, stem elongation, leaf angle, rachis length, inflorescence branching, floral organ number, plastochron, anthesis time, and tolerances to submergence, salinity, and cold. The protein localizes to secretory vesicles, the plant-type vacuole, and extracellularly. Studies of related genes in other species link the family to seed viability, seed size, and heterosis.
