Annexins are Ca2+-dependent phospholipids-binding proteins constituting evolutionary conserved multigene family that widely distributed throughout animals and plants. OsANN4 is a member of rice annexin protein family. However, the functions and mechanisms of OsANN4 in stress responses and signal pathways remain unclear. GUS staining assay and quantitative RT-PCR indicated that the expression of OsANN4 is tissue-specific. In this study, OsANN4 expression was high at seedling stage. The plants which knocking down OsANN4 through RNA interference were more sensitive to ABA at the seeds germination stage comparing to wild type. It suggested that OsANN4 was involved in response to ABA signaling under abiotic stress. Furthermore, yeast two-hybrid assays demonstrated that OsANN4 interacted with OsCDPK24. This may provide potential regulation cross-talk in the abiotic stress response.
