GRP1 — Sorghum bicolor

Summary

SORBI_3001G036200 (SbGRP1) encodes a glycine-rich protein (GRP) family member. The gene is associated with immune response, defense response, and innate immunity, and its product localizes to the nucleus and binds proteins. SbGRP1 has been connected to drought stress response, cell elongation, and spikelet development. Studies of related genes in other species link the GRP family to grain thickness, grain width, grain weight, grain size, and grain quality, as well as to lignin content, anthocyanin content, cold tolerance, drought tolerance, plant growth and development, and root morphology traits.
