Mass spectrometry analysis results of GNP2 phosphorylation of Gnp4 in rice

The number of grains per panicle is one of the important factors affecting rice yield. In this study, we found that GNP2 can phosphorylate Gnp4, a factor influencing grain number per panicle in rice. Therefore, we conducted a mass spectrometry analysis of the phosphorylation sites of Gnp4.
