CS1 — Oryza sativa Indica Group

Summary

BGIOSGA023662 (CS1, also known as OiCS1) on chromosome 7 of Indica rice encodes a haem peroxidase of the Ccp1-like family, with L-ascorbate peroxidase activity (EC 1.11.1.11). The gene is associated with diverse biological processes including cellular oxidant detoxification, ROS metabolism, H2O2-mediated signaling, chloroplast-nucleus signaling, and auxin metabolism. It is linked to traits such as bacterial blight disease resistance, drought stress, photosynthesis, plant growth and architecture, seed viability, flowering time, leaf senescence, and root development. The encoded protein localizes to the chloroplast thylakoid membrane, peroxisome membrane, and stress granules. Studies of related genes in other species connect the family to oxidative stress tolerance, heat and salt stress responses, and chloroplast retrograde signalling.
