GS2 — Oryza sativa Japonica

Summary

OsGS2 (Os02g0735200) encodes a glutamine synthetase (EC 6.3.1.2). In rice, this gene is associated with responses to salt, drought, osmotic stress, and aluminium toxicity, as well as with abiotic and biotic stress tolerance. It is linked to numerous grain and yield traits, including grain size, shape, thickness, weight, amylose content, spikelet number, panicle number, tiller number, and grain filling period. Associations also extend to photosynthetic rate, chlorophyll content, leaf senescence, root length, lateral root length, nitrogen content, sucrose content, and flowering time. The encoded protein is predicted to localize to the chloroplast thylakoid, stroma, and envelope, as well as to the cytosol and apoplast, and is linked to processes such as photorespiration, the TCA cycle, and ammonium assimilation.
