RP1 — Sorghum bicolor

Summary

SbRP1 (SORBI_3002G324700) on sorghum chromosome 2 encodes a protein with the PPDK_reg domain, with phosphotransferase, protein serine/threonine kinase, and protein phosphatase activities, and is localized to the chloroplast stroma and cytosol. This gene is associated with regulation of pyruvate, phosphate dikinase. Studies of related genes in other species link the family to biomass yield, water use efficiency, photochemical quenching, drought tolerance, and root morphology traits, as well as to stem rust and iron concentration.
