In most angiosperms, the inheritance of the plastid takes place in a typical maternal manner. However, very less information is available about if the existence of structural variations or not in plastid genomes (plastomes) between maternal parents and their progenies. In order to find the answer, the plastomes of a stable rice backcross inbred line (BIL) population developed by us in precious study were analyzed. Although the genomic structure of plastomes were stable, repeat-mediated recombination, gene expression, and RNA-editing were extensively varied among maternal line and BILs. These novel findings unraveled an unusual mystery of the maternal inheritance in plastomes. The current piece of work will greatly develop our understanding of the plant nucleo-cytoplasmic interaction and their potential role in plant growth and developmental processes.
