To identify the phosphorylation site of ZmRR1 by ZmMPK8 in vitro, 10 µg GST-ZmRR1 and 1 µg His-ZmMPK8 purified proteins were incubated in 20 µl of protein kinase reaction buffer containing 20 mM MgCl2, 50 mM Tris-HCl pH 7.5, 1 mM DTT, and 50 µM ATP, at 30°C for 30 min. The reaction products were red...
