CSD1 — Sorghum bicolor

Summary

SORBI_3001G453800 (SbCSD1) on sorghum chromosome 1 encodes a protein with a copper/zinc superoxide dismutase domain and is annotated with copper binding and superoxide dismutase activity (EC 1.15.1.1). The gene is associated with cellular responses to ozone, high light intensity, UV-B, sucrose, and copper, as well as water homeostasis, gene silencing by miRNA, and removal of superoxide radicals. It is linked to thylakoid, chloroplast stroma, apoplast, and plasmalemma localisation. SbCSD1 is associated with drought tolerance, salt stress tolerance, thermotolerance, bacterial blight disease resistance, photosynthetic rate, proline content, and heavy-metal stress responses. Studies of related genes in other species link the family to oxidative stress tolerance, aluminum tolerance, fungal immunity, and seed and growth traits such as seed weight, seedling vigor, and leaf chlorophyll content.
