CS1 — Oryza sativa Japonica

Summary

OsCS1 (OS12G0178200) encodes a haem peroxidase with L-ascorbate peroxidase activity (EC 1.11.1.11), belonging to the Ccp1-like and peroxidase_I families. The gene is associated with diverse biological processes including the ascorbate-glutathione cycle, cellular oxidant detoxification, chloroplast-nucleus signaling, and aerenchyma formation. In rice, it has been linked to plant growth, architecture, leaf and seed traits, height, senescence, and responses to abiotic stresses such as salt, cold, and blast disease, as well as gall midge resistance and thousand kernel weight. The encoded protein localizes to the peroxisome membrane, chloroplast outer membrane, thylakoid, and stress granules. Additional associations include traits such as aluminum tolerance, bacterial blight resistance, carotenoid content, tiller angle, and seed viability.
