•In SL ovules, low expressions of MCM complex, etc. led to abnormal DNA replication.•The expressions of PARP2, etc. implied the accumulation of DNA DSBs.•SL ovules failed to repair the DNA damage, and the PCD occurred.•The deficiency of ETF-QO hindered the progress of FNMM.•FNMM stopped, which resul...
