| Outline of Final Research Achievements |
Mitochondria and chloroplast are deeply involved in the important activities in the cell through the complex interaction between nuclear genome. To examine the evolutionary stability of the plasmon, we evaluated the molecular variation in chloroplast and mitochondrial genome between the alloplasmic wheat line with an alien cytoplasm and the donor line of the cytoplasm. This alloplasmic line has been maintained for more than 60 generation by repeated backcrossing. No variation was identified between the alloplasmic line and the donor line, indicated the evolutionary stable nature of the plasmon in wheat. In addition, we found that the intramolecular recombination in mitochondrial genome occurs in almost all of the tissues, although the frequency is very low as well as variable among tissues.
