RP1 — Sorghum bicolor

Summary

SORBI_3002G324400 (SbRP1) on sorghum chromosome 2 encodes a protein belonging to the PPDK_reg and Pyrv_Pi_dikinase_reg_chlpt domain families, with enzyme activities including 2.7.4.27, 2.7.11.32, phosphotransferase, protein phosphatase, and protein serine/threonine kinase activity, and binds ATP. The product is associated with the chloroplast stroma and cytosol. Studies of related genes in other species link the family to stem rust, iron concentration, biomass yield, water use efficiency, photochemical quenching, root morphology, and drought tolerance.
