The endogenous phosphorylation pattern of the extract prepared from rice young panicle has been examined. The extract was phosphorylated in vitro by incubating with [gamma-32p] ATP, and then analyzed by SDS-PAGE and autoradiography. At least eight major phosphoproteins with apparent molecular weights of 70, 60, 52, 40, 33, 30, 20, 16 and 15 kd were detected in the crude extract of rice young panicle. The pp70 which represents the major phosphoprotein in the crude extract of young panicle of rice is a cytosolic protein. Photoaffinity labeling with 8-azido-ATP revealed that a major protein with molecular weight 42,000 dalton but not pp70 can be specifically bound ATP. This suggests that pp70 is not a protein kinase itself, but a substrate of protein kinase. The in vitro phosphorylation of the pp70 occurs at a serine or threonine residue and is time and temperature dependent. The phosphorylation of pp70 does not depend by exogenous Ca++ or cAMP, suggesting that pp70 is a major substrate of an Ca++ or cAMP independent protein kinase in rice young panicle.
