CS1 — Oryza sativa Indica Group

Summary

BGIOSGA026526 (CS1, also known as OiATAPX01) in indica rice encodes a haem peroxidase family protein 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 has been linked to traits such as bacterial blight disease resistance, plant reproduction, shoot meristem development, seed viability, flowering time, leaf senescence, and root length. The encoded protein localizes to the chloroplast thylakoid membrane, peroxisome membrane, and stress granules. Related genes in other species are linked to salt, heat, and oxidative stress tolerance, as well as root growth and hydrogen peroxide accumulation.
