CS1 — Oryza sativa Indica Group

Summary

BGIOSGA026644 (CS1, OiCS1) in Indica rice 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 cellular oxidant detoxification, ROS metabolism, H2O2-mediated signaling, chloroplast-nucleus signaling, and cell cycle G2/M phase transition. It has been linked to traits such as bacterial blight disease resistance, plant reproduction, viral disease response, vegetative to reproductive phase transition, shoot meristem development, aphid response, cadmium concentration, plant morphology, adventitious rootless, inflorescence morphology, cell growth and development, seed viability, plant tissue development, floral organ identity, cell cycle, chloroplast development, leaf morphology, jasmonic acid content, days to flowering, stomatal complex closure time, leaf composition, seedling growth and development, low temperature stress response, photosynthetic rate, leaf senescence, flowering time, root length, disease tolerance, and plant growth and development. Localization evidence connects the product to the chloroplast thylakoid, peroxisome membrane, and stress granules. Related genes in other species link the family to salt, heat, and oxidative stress tolerance, as well as hydrogen peroxide accumulation and root growth.
