Plastome-genome interactions affect plastid transmission in Oenothera

The influence of nuclear genomes on plastid inheritance in Oenothera was determined. The transmission of four Oenothera plastom types was simultaneously compared in different nuclear backgroud. Results of the genetic crosses showed that the plastome-genome interactions affected the plastid transmission by lowering the efficiency of plastid multiplication after fertilization. In addition, parental traits which influence fertilization also affected plastid transmission.
