Abstract	Protein phosphorylation is an important post-translational modification that can regulate the protein function. The current knowledge on the phosphorylation status of plant oil body (OB) proteins is inadequate. This present study identifies the distinct physiological substrates of Arabidopsis serine/threonine/tyrosine protein kinase (STYK) and its role in seed oil accumulation; the role of Arabidopsis OLE1, a major seed OB protein has also been elucidated. In vitro kinase assay followed by massspectrometry identifies residue that are phosphorylated by STYK. Further, co-expression of OLE1 and STYK in yeast cells increases the cellular lipid levels and reduces the total lipid when OLE1 was replacedwith OLE1T166A. Moreover, in vivo experiments with OB isolated from wild-type and styk knock-outlines show the ability of STYK to phosphorylate distinct OB proteins. OLE1T166A mutant and Arabidopsisstyk mutant demonstrate the significant reduction of its substrate phosphorylation. styk mutant line significantly reduces the amount of total seed oil as compared to wild-type seeds. Together, our results provide the evidences that Arabidopsis At 2G24360 (STYK) is phosphorylating oil body proteins and the phosphorylation regulates the oil content in Arabidopsis seeds.
