Moreover, our result showed that the C16:0,C18:0, C18:1 and C18:2 FAs were significantly reduced after down regulation of OsLTPL36 (Table 2). It was reported that 16:0 and 18:0 FAs are involved in multiple biological processes, including production of glycerol lipids and phospholipids that are important in cell signaling for embryo development [36]. Thus, it is possible that OsLTPL36 might transfer lipid molecules for embryo development cell signaling although further studies are needed to dissect the molecular mechanism.
