The impact of cell cycle on plant immunity was indicated by the enhancement of disease resistance with overexpressing  OSD1  and  UVI4  genes that are negative regulators of cell cycle controller APC (anaphase promoting complex).  CPR5  is another gene that is implicated in cell cycle regulation and plant immunity, but its mode of action is not known. Here we report the analysis of genetic requirement for the function of  UVI4  and  OSD1  in cell cycle progression control and in particular the involvement of  CPR5  in this regulation. We show that the APC activator CCS52A1 partially mediates the function of  OSD1  and  UVI4  in female gametophyte development. We found that the  cpr5  mutation suppresses the endoreduplication defect in the  uvi4  single mutant and partially rescued the gametophyte development defect in the  osd1 uvi4  double mutant while the  uvi4  mutation enhances the  cpr5  defects in trichome branching and plant disease resistance. In addition, cyclin B1 genes  CYCB1;1 ,  CYCB1;2 , and  CYCB1;4  are upregulated in  cpr5 . Therefore,  CPR5  has a large role in cell cycle regulation and this role has a complex interaction with that of  UVI4  and  OSD1 . This study further indicates an intrinsic link between plant defense responses and cell cycle progression.
